-/**
- * fw_pm_notify - notifier for suspend/resume
- * @notify_block: unused
- * @mode: mode we are switching to
- * @unused: unused
- *
- * Used to modify the firmware_class state as we move in between states.
- * The firmware_class implements a firmware cache to enable device driver
- * to fetch firmware upon resume before the root filesystem is ready. We
- * disable API calls which do not use the built-in firmware or the firmware
- * cache when we know these calls will not work.
- *
- * The inner logic behind all this is a bit complex so it is worth summarizing
- * the kernel's own suspend/resume process with context and focus on how this
- * can impact the firmware API.
- *
- * First a review on how we go to suspend::
- *
- *	pm_suspend() --> enter_state() -->
- *	sys_sync()
- *	suspend_prepare() -->
- *		__pm_notifier_call_chain(PM_SUSPEND_PREPARE, ...);
- *		suspend_freeze_processes() -->
- *			freeze_processes() -->
- *				__usermodehelper_set_disable_depth(UMH_DISABLED);
- *				freeze all tasks ...
- *			freeze_kernel_threads()
- *	suspend_devices_and_enter() -->
- *		dpm_suspend_start() -->
- *				dpm_prepare()
- *				dpm_suspend()
- *		suspend_enter()  -->
- *			platform_suspend_prepare()
- *			dpm_suspend_late()
- *			freeze_enter()
- *			syscore_suspend()
- *
- * When we resume we bail out of a loop from suspend_devices_and_enter() and
- * unwind back out to the caller enter_state() where we were before as follows::
- *
- * 	enter_state() -->
- *	suspend_devices_and_enter() --> (bail from loop)
- *		dpm_resume_end() -->
- *			dpm_resume()
- *			dpm_complete()
- *	suspend_finish() -->
- *		suspend_thaw_processes() -->
- *			thaw_processes() -->
- *				__usermodehelper_set_disable_depth(UMH_FREEZING);
- *				thaw_workqueues();
- *				thaw all processes ...
- *				usermodehelper_enable();
- *		pm_notifier_call_chain(PM_POST_SUSPEND);
- *
- * fw_pm_notify() works through pm_notifier_call_chain().

+ * The Basic Flash Parameter Table is the main and only mandatory table as

+ * It provides us with the total size (memory density) of the data array and

+ * commands.
+ * For Fast READ commands, it also gives the number of mode clock cycles and
+ * wait states (regrouped in the number of dummy clock cycles) for each
+ * supported instruction op code.
+ * For Page Program, the page size is now available since JESD216 rev A, however
+ * the supported instruction op codes are still not provided.
+ * For Sector Erase commands, this table stores the supported instruction op
+ * codes and the associated sector sizes.
+ * Finally, the Quad Enable Requirements (QER) are also available since JESD216
+ * rev A. The QER bits encode the manufacturer dependent procedure to be
+ * executed to set the Quad Enable (QE) bit in some internal register of the
+ * Quad SPI memory. Indeed the QE bit, when it exists, must be set before
+ * sending any Quad SPI command to the memory. Actually, setting the QE bit
+ * tells the memory to reassign its WP# and HOLD#/RESET# pins to functions IO2
+ * and IO3 hence enabling 4 (Quad) I/O lines.

+ * For the reader path, the real_dev->rx_handler_data is called in the TX / RX
+ * path. We only need rcu_read_lock() for these scenarios. In these cases,
+ * the rcu_read_lock() is held in __dev_queue_xmit() and
+ * netif_receive_skb_internal(), so readers need to use rcu_dereference_rtnl()
+ * to get the relevant information. For dev list reading, we again acquire
+ * rcu_read_lock() in rmnet_dellink() for netdev_master_upper_dev_get_rcu().
+ * We also use unregister_netdevice_many() to free all rmnet devices in

+    help
+      Say 'Y' here to add support for MediaTek T-PHY driver,
+      it supports multiple usb2.0, usb3.0 ports, PCIe and
+	  SATA, and meanwhile supports two version T-PHY which have
+	  different banks layout, the T-PHY with shared banks between
+	  multi-ports is first version, otherwise is second veriosn,
+	  so you can easily distinguish them by banks layout.

+	---help---
+	  Say Y here if you want to build support for the IrDA (TM) protocols.
+	  The Infrared Data Associations (tm) specifies standards for wireless
+	  infrared communication and is supported by most laptops and PDA's.
+
+	  To use Linux support for the IrDA (tm) protocols, you will also need
+	  some user-space utilities like irattach.  For more information, see
+	  the file <file:Documentation/networking/irda.txt>.  You also want to
+	  read the IR-HOWTO, available at
+	  <http://www.tldp.org/docs.html#howto>.
+
+	  If you want to exchange bits of data (vCal, vCard) with a PDA, you
+	  will need to install some OBEX application, such as OpenObex :
+	  <http://sourceforge.net/projects/openobex/>
+
+	  To compile this support as a module, choose M here: the module will
+	  be called irda.

+	  Ultra allows to exchange data over IrDA with really simple devices
+	  (watch, beacon) without the overhead of the IrDA protocol (no handshaking,
+	  no management frames, simple fixed header).
+	  Ultra is available as a special socket : socket(AF_IRDA, SOCK_DGRAM, 1);

+	help
+	  Say Y here if you want IrLMP to cache the last LSAP used.  This
+	  makes sense since most frames will be sent/received on the same
+	  connection.  Enabling this option will save a hash-lookup per frame.
+
+	  If unsure, say Y.
+
+config IRDA_FAST_RR
+	bool "Fast RRs (low latency)"
+	depends on IRDA
+	---help---
+	  Say Y here is you want IrLAP to send fast RR (Receive Ready) frames
+	  when acting as a primary station.
+	  Disabling this option will make latency over IrDA very bad. Enabling
+	  this option will make the IrDA stack send more packet than strictly
+	  necessary, thus reduce your battery life (but not that much).
+
+	  Fast RR will make IrLAP send out a RR frame immediately when
+	  receiving a frame if its own transmit queue is currently empty. This
+	  will give a lot of speed improvement when receiving much data since
+	  the secondary station will not have to wait the max. turn around
+	  time (usually 500ms) before it is allowed to transmit the next time.
+	  If the transmit queue of the secondary is also empty, the primary will
+	  start backing-off before sending another RR frame, waiting longer
+	  each time until the back-off reaches the max. turn around time.
+	  This back-off increase in controlled via
+	  /proc/sys/net/irda/fast_poll_increase
+
+	  If unsure, say Y.
+

+	help
+	  Say Y here if you want the IrDA subsystem to write debug information
+	  to your syslog. You can change the debug level in
+	  /proc/sys/net/irda/debug .
+	  When this option is enabled, the IrDA also perform many extra internal
+	  verifications which will usually prevent the kernel to crash in case of
+	  bugs.
+
+	  If unsure, say Y (since it makes it easier to find the bugs).

+ *     Linux-IrDA now supports four different types of IrDA sockets:
+ *
+ *     o SOCK_STREAM:    TinyTP connections with SAR disabled. The
+ *                       max SDU size is 0 for conn. of this type
+ *     o SOCK_SEQPACKET: TinyTP connections with SAR enabled. TTP may
+ *                       fragment the messages, but will preserve
+ *                       the message boundaries
+ *     o SOCK_DGRAM:     IRDAPROTO_UNITDATA: TinyTP connections with Unitdata
+ *                       (unreliable) transfers
+ *                       IRDAPROTO_ULTRA: Connectionless and unreliable data
+ *

+	help
+	  Say Y here if you want to build support for the IrLAN protocol.
+	  To compile it as a module, choose M here: the module will be called
+	  irlan.  IrLAN emulates an Ethernet and makes it possible to put up
+	  a wireless LAN using infrared beams.
+
+	  The IrLAN protocol can be used to talk with infrared access points
+	  like the HP NetbeamIR, or the ESI JetEye NET.  You can also connect
+	  to another Linux machine running the IrLAN protocol for ad-hoc
+	  networking!

+/************************** DOCUMENTATION ***************************/
+/*
+ * What is IrNET
+ * -------------
+ * IrNET is a protocol allowing to carry TCP/IP traffic between two
+ * IrDA peers in an efficient fashion. It is a thin layer, passing PPP
+ * packets to IrTTP and vice versa. It uses PPP in synchronous mode,
+ * because IrTTP offer a reliable sequenced packet service (as opposed
+ * to a byte stream). In fact, you could see IrNET as carrying TCP/IP
+ * in a IrDA socket, using PPP to provide the glue.
+ *
+ * The main difference with traditional PPP over IrCOMM is that we
+ * avoid the framing and serial emulation which are a performance
+ * bottleneck. It also allows multipoint communications in a sensible
+ * fashion.
+ *
+ * The main difference with IrLAN is that we use PPP for the link
+ * management, which is more standard, interoperable and flexible than
+ * the IrLAN protocol. For example, PPP adds authentication,
+ * encryption, compression, header compression and automated routing
+ * setup. And, as IrNET let PPP do the hard work, the implementation
+ * is much simpler than IrLAN.
+ *
+ * The Linux implementation
+ * ------------------------
+ * IrNET is written on top of the Linux-IrDA stack, and interface with
+ * the generic Linux PPP driver. Because IrNET depend on recent
+ * changes of the PPP driver interface, IrNET will work only with very
+ * recent kernel (2.3.99-pre6 and up).
+ *
+ * The present implementation offer the following features :
+ *	o simple user interface using pppd
+ *	o efficient implementation (interface directly to PPP and IrTTP)
+ *	o addressing (you can specify the name of the IrNET recipient)
+ *	o multipoint operation (limited by IrLAP specification)
+ *	o information in /proc/net/irda/irnet
+ *	o IrNET events on /dev/irnet (for user space daemon)
+ *	o IrNET daemon (irnetd) to automatically handle incoming requests
+ *	o Windows 2000 compatibility (tested, but need more work)
+ * Currently missing :
+ *	o Lot's of testing (that's your job)
+ *	o Connection retries (may be too hard to do)
+ *	o Check pppd persist mode
+ *	o User space daemon (to automatically handle incoming requests)
+ *
+ * The setup is not currently the most easy, but this should get much
+ * better when everything will get integrated...
+ *
+ * Acknowledgements
+ * ----------------
+ * This module is based on :
+ *	o The PPP driver (ppp_synctty/ppp_generic) by Paul Mackerras
+ *	o The IrLAN protocol (irlan_common/XXX) by Dag Brattli
+ *	o The IrSock interface (af_irda) by Dag Brattli
+ *	o Some other bits from the kernel and my drivers...
+ * Infinite thanks to those brave souls for providing the infrastructure
+ * upon which IrNET is built.
+ *
+ * Thanks to all my colleagues in HP for helping me. In particular,
+ * thanks to Salil Pradhan and Bill Serra for W2k testing...
+ * Thanks to Luiz Magalhaes for irnetd and much testing...
+ *
+ * Thanks to Alan Cox for answering lot's of my stupid questions, and
+ * to Paul Mackerras answering my questions on how to best integrate
+ * IrNET and pppd.
+ *
+ * Jean II
+ *
+ * Note on some implementations choices...
+ * ------------------------------------
+ *	1) Direct interface vs tty/socket
+ * I could have used a tty interface to hook to ppp and use the full
+ * socket API to connect to IrDA. The code would have been easier to
+ * maintain, and maybe the code would have been smaller...
+ * Instead, we hook directly to ppp_generic and to IrTTP, which make
+ * things more complicated...
+ *
+ * The first reason is flexibility : this allow us to create IrNET
+ * instances on demand (no /dev/ircommX crap) and to allow linkname
+ * specification on pppd command line...
+ *
+ * Second reason is speed optimisation. If you look closely at the
+ * transmit and receive paths, you will notice that they are "super lean"
+ * (that's why they look ugly), with no function calls and as little data
+ * copy and modification as I could...
+ *
+ *	2) irnetd in user space
+ * irnetd is implemented in user space, which is necessary to call pppd.
+ * This also give maximum benefits in term of flexibility and customability,
+ * and allow to offer the event channel, useful for other stuff like debug.
+ *
+ * On the other hand, this require a loose coordination between the
+ * present module and irnetd. One critical area is how incoming request
+ * are handled.
+ * When irnet receive an incoming request, it send an event to irnetd and
+ * drop the incoming IrNET socket.
+ * irnetd start a pppd instance, which create a new IrNET socket. This new
+ * socket is then connected in the originating node to the pppd instance.
+ * At this point, in the originating node, the first socket is closed.
+ *
+ * I admit, this is a bit messy and waste some resources. The alternative
+ * is caching incoming socket, and that's also quite messy and waste
+ * resources.
+ * We also make connection time slower. For example, on a 115 kb/s link it
+ * adds 60ms to the connection time (770 ms). However, this is slower than
+ * the time it takes to fire up pppd on my P133...
+ *
+ *
+ * History :
+ * -------
+ *
+ * v1 - 15.5.00 - Jean II
+ *	o Basic IrNET (hook to ppp_generic & IrTTP - incl. multipoint)
+ *	o control channel on /dev/irnet (set name/address)
+ *	o event channel on /dev/irnet (for user space daemon)
+ *
+ * v2 - 5.6.00 - Jean II
+ *	o Enable DROP_NOT_READY to avoid PPP timeouts & other weirdness...
+ *	o Add DISCONNECT_TO event and rename DISCONNECT_FROM.
+ *	o Set official device number alloaction on /dev/irnet
+ *
+ * v3 - 30.8.00 - Jean II
+ *	o Update to latest Linux-IrDA changes :
+ *		- queue_t => irda_queue_t
+ *	o Update to ppp-2.4.0 :
+ *		- move irda_irnet_connect from PPPIOCATTACH to TIOCSETD
+ *	o Add EXPIRE event (depend on new IrDA-Linux patch)
+ *	o Switch from `hashbin_remove' to `hashbin_remove_this' to fix
+ *	  a multilink bug... (depend on new IrDA-Linux patch)
+ *	o fix a self->daddr to self->raddr in irda_irnet_connect to fix
+ *	  another multilink bug (darn !)
+ *	o Remove LINKNAME_IOCTL cruft
+ *
+ * v3b - 31.8.00 - Jean II
+ *	o Dump discovery log at event channel startup
+ *
+ * v4 - 28.9.00 - Jean II
+ *	o Fix interaction between poll/select and dump discovery log
+ *	o Add IRNET_BLOCKED_LINK event (depend on new IrDA-Linux patch)
+ *	o Add IRNET_NOANSWER_FROM event (mostly to help support)
+ *	o Release flow control in disconnect_indication
+ *	o Block packets while connecting (speed up connections)
+ *
+ * v5 - 11.01.01 - Jean II
+ *	o Init self->max_header_size, just in case...
+ *	o Set up ap->chan.hdrlen, to get zero copy on tx side working.
+ *	o avoid tx->ttp->flow->ppp->tx->... loop, by checking flow state
+ *		Thanks to Christian Gennerat for finding this bug !
+ *	---
+ *	o Declare the proper MTU/MRU that we can support
+ *		(but PPP doesn't read the MTU value :-()
+ *	o Declare hashbin HB_NOLOCK instead of HB_LOCAL to avoid
+ *		disabling and enabling irq twice
+ *
+ * v6 - 31.05.01 - Jean II
+ *	o Print source address in Found, Discovery, Expiry & Request events
+ *	o Print requested source address in /proc/net/irnet
+ *	o Change control channel input. Allow multiple commands in one line.
+ *	o Add saddr command to change ap->rsaddr (and use that in IrDA)
+ *	---
+ *	o Make the IrDA connection procedure totally asynchronous.
+ *	  Heavy rewrite of the IAS query code and the whole connection
+ *	  procedure. Now, irnet_connect() no longer need to be called from
+ *	  a process context...
+ *	o Enable IrDA connect retries in ppp_irnet_send(). The good thing
+ *	  is that IrDA connect retries are directly driven by PPP LCP
+ *	  retries (we retry for each LCP packet), so that everything
+ *	  is transparently controlled from pppd lcp-max-configure.
+ *	o Add ttp_connect flag to prevent rentry on the connect procedure
+ *	o Test and fixups to eliminate side effects of retries
+ *
+ * v7 - 22.08.01 - Jean II
+ *	o Cleanup : Change "saddr = 0x0" to "saddr = DEV_ADDR_ANY"
+ *	o Fix bug in BLOCK_WHEN_CONNECT introduced in v6 : due to the
+ *	  asynchronous IAS query, self->tsap is NULL when PPP send the
+ *	  first packet.  This was preventing "connect-delay 0" to work.
+ *	  Change the test in ppp_irnet_send() to self->ttp_connect.
+ *
+ * v8 - 1.11.01 - Jean II
+ *	o Tighten the use of self->ttp_connect and self->ttp_open to
+ *	  prevent various race conditions.
+ *	o Avoid leaking discovery log and skb
+ *	o Replace "self" with "server" in irnet_connect_indication() to
+ *	  better detect cut'n'paste error ;-)
+ *
+ * v9 - 29.11.01 - Jean II
+ *	o Fix event generation in disconnect indication that I broke in v8
+ *	  It was always generation "No-Answer" because I was testing ttp_open
+ *	  just after clearing it. *blush*.
+ *	o Use newly created irttp_listen() to fix potential crash when LAP
+ *	  destroyed before irnet module removed.
+ *
+ * v10 - 4.3.2 - Jean II
+ *	o When receiving a disconnect indication, don't reenable the
+ *	  PPP Tx queue, this will trigger a reconnect. Instead, close
+ *	  the channel, which will kill pppd...
+ *
+ * v11 - 20.3.02 - Jean II
+ *	o Oops ! v10 fix disabled IrNET retries and passive behaviour.
+ *	  Better fix in irnet_disconnect_indication() :
+ *	  - if connected, kill pppd via hangup.
+ *	  - if not connected, reenable ppp Tx, which trigger IrNET retry.
+ *
+ * v12 - 10.4.02 - Jean II
+ *	o Fix race condition in irnet_connect_indication().
+ *	  If the socket was already trying to connect, drop old connection
+ *	  and use new one only if acting as primary. See comments.
+ *
+ * v13 - 30.5.02 - Jean II
+ *	o Update module init code
+ *
+ * v14 - 20.2.03 - Jean II
+ *	o Add discovery hint bits in the control channel.
+ *	o Remove obsolete MOD_INC/DEC_USE_COUNT in favor of .owner
+ *
+ * v15 - 7.4.03 - Jean II
+ *	o Replace spin_lock_irqsave() with spin_lock_bh() so that we can
+ *	  use ppp_unit_number(). It's probably also better overall...
+ *	o Disable call to ppp_unregister_channel(), because we can't do it.

+/*
+ * Notes on the concurrent access to hashbin and other SMP issues
+ * -------------------------------------------------------------
+ *	Hashbins are very often in the IrDA stack a global repository of
+ * information, and therefore used in a very asynchronous manner following
+ * various events (driver calls, timers, user calls...).
+ *	Therefore, very often it is highly important to consider the
+ * management of concurrent access to the hashbin and how to guarantee the
+ * consistency of the operations on it.
+ *
+ *	First, we need to define the objective of locking :
+ *		1) Protect user data (content pointed by the hashbin)
+ *		2) Protect hashbin structure itself (linked list in each bin)
+ *
+ *			     OLD LOCKING
+ *			     -----------
+ *
+ *	The previous locking strategy, either HB_LOCAL or HB_GLOBAL were
+ * both inadequate in *both* aspect.
+ *		o HB_GLOBAL was using a spinlock for each bin (local locking).
+ *		o HB_LOCAL was disabling irq on *all* CPUs, so use a single
+ *		  global semaphore.
+ *	The problems were :
+ *		A) Global irq disabling is no longer supported by the kernel
+ *		B) No protection for the hashbin struct global data
+ *			o hashbin_delete()
+ *			o hb_current
+ *		C) No protection for user data in some cases
+ *
+ *	A) HB_LOCAL use global irq disabling, so doesn't work on kernel
+ * 2.5.X. Even when it is supported (kernel 2.4.X and earlier), its
+ * performance is not satisfactory on SMP setups. Most hashbins were
+ * HB_LOCAL, so (A) definitely need fixing.
+ *	B) HB_LOCAL could be modified to fix (B). However, because HB_GLOBAL
+ * lock only the individual bins, it will never be able to lock the
+ * global data, so can't do (B).
+ *	C) Some functions return pointer to data that is still in the
+ * hashbin :
+ *		o hashbin_find()
+ *		o hashbin_get_first()
+ *		o hashbin_get_next()
+ *	As the data is still in the hashbin, it may be changed or free'd
+ * while the caller is examinimg the data. In those case, locking can't
+ * be done within the hashbin, but must include use of the data within
+ * the caller.
+ *	The caller can easily do this with HB_LOCAL (just disable irqs).
+ * However, this is impossible with HB_GLOBAL because the caller has no
+ * way to know the proper bin, so don't know which spinlock to use.
+ *
+ *	Quick summary : can no longer use HB_LOCAL, and HB_GLOBAL is
+ * fundamentally broken and will never work.
+ *
+ *			     NEW LOCKING
+ *			     -----------
+ *
+ *	To fix those problems, I've introduce a few changes in the
+ * hashbin locking :
+ *		1) New HB_LOCK scheme
+ *		2) hashbin->hb_spinlock
+ *		3) New hashbin usage policy
+ *
+ * HB_LOCK :
+ * -------
+ *	HB_LOCK is a locking scheme intermediate between the old HB_LOCAL
+ * and HB_GLOBAL. It uses a single spinlock to protect the whole content
+ * of the hashbin. As it is a single spinlock, it can protect the global
+ * data of the hashbin and not only the bins themselves.
+ *	HB_LOCK can only protect some of the hashbin calls, so it only lock
+ * call that can be made 100% safe and leave other call unprotected.
+ *	HB_LOCK in theory is slower than HB_GLOBAL, but as the hashbin
+ * content is always small contention is not high, so it doesn't matter
+ * much. HB_LOCK is probably faster than HB_LOCAL.
+ *
+ * hashbin->hb_spinlock :
+ * --------------------
+ *	The spinlock that HB_LOCK uses is available for caller, so that
+ * the caller can protect unprotected calls (see below).
+ *	If the caller want to do entirely its own locking (HB_NOLOCK), he
+ * can do so and may use safely this spinlock.
+ *	Locking is done like this :
+ *		spin_lock_irqsave(&hashbin->hb_spinlock, flags);
+ *	Releasing the lock :
+ *		spin_unlock_irqrestore(&hashbin->hb_spinlock, flags);
+ *
+ * Safe & Protected calls :
+ * ----------------------
+ *	The following calls are safe or protected via HB_LOCK :
+ *		o hashbin_new()		-> safe
+ *		o hashbin_delete()
+ *		o hashbin_insert()
+ *		o hashbin_remove_first()
+ *		o hashbin_remove()
+ *		o hashbin_remove_this()
+ *		o HASHBIN_GET_SIZE()	-> atomic
+ *
+ *	The following calls only protect the hashbin itself :
+ *		o hashbin_lock_find()
+ *		o hashbin_find_next()
+ *
+ * Unprotected calls :
+ * -----------------
+ *	The following calls need to be protected by the caller :
+ *		o hashbin_find()
+ *		o hashbin_get_first()
+ *		o hashbin_get_next()
+ *
+ * Locking Policy :
+ * --------------
+ *	If the hashbin is used only in a single thread of execution
+ * (explicitly or implicitely), you can use HB_NOLOCK
+ *	If the calling module already provide concurrent access protection,
+ * you may use HB_NOLOCK.
+ *
+ *	In all other cases, you need to use HB_LOCK and lock the hashbin
+ * every time before calling one of the unprotected calls. You also must
+ * use the pointer returned by the unprotected call within the locked
+ * region.
+ *
+ * Extra care for enumeration :
+ * --------------------------
+ *	hashbin_get_first() and hashbin_get_next() use the hashbin to
+ * store the current position, in hb_current.
+ *	As long as the hashbin remains locked, this is safe. If you unlock
+ * the hashbin, the current position may change if anybody else modify
+ * or enumerate the hashbin.
+ *	Summary : do the full enumeration while locked.
+ *
+ *	Alternatively, you may use hashbin_find_next(). But, this will
+ * be slower, is more complex to use and doesn't protect the hashbin
+ * content. So, care is needed here as well.
+ *
+ * Other issues :
+ * ------------
+ *	I believe that we are overdoing it by using spin_lock_irqsave()
+ * and we should use only spin_lock_bh() or similar. But, I don't have
+ * the balls to try it out.
+ *	Don't believe that because hashbin are now (somewhat) SMP safe
+ * that the rest of the code is. Higher layers tend to be safest,
+ * but LAP and LMP would need some serious dedicated love.

+For Raspbian users only
+=======================
+Since Raspbian supports device tree overlays, you may use and overlay, instead
+of editing your boards device tree.
+For using the overlay, you need to compile the file pi433-overlay.dts you can
+find aside to this documentation.
+The file needs to be compiled - either manually or by integration in your kernel
+source tree. For a manual compile, you may use a command line like the following:
+'linux/scripts/dtc/dtc -@ -I dts -O dtb -o pi433.dtbo pi433-overlay.dts'
+
+For compiling inside of the kernel tree, you need to copy pi433-overlay.dts to
+arch/arm/boot/dts/overlays and you need to add the file to the list of files
+in the Makefile over there. Execute 'make dtbs' in kernel tree root to make the
+kernel make files compile the device tree overlay for you.

+Introduction
+============
+This driver is for controlling pi433, a radio module for the Raspberry Pi
+(www.pi433.de). It supports transmission and reception. It can be opened
+by multiple applications for transmission and reception. While transmit
+jobs were queued and process automatically in the background, the first
+application asking for reception will block out all other applications
+until something gets received terminates the read request.
+The driver supports on the fly reloading of the hardware fifo of the rf
+chip, thus enabling for much longer telegrams then hardware fifo size.
+
+Discription of driver operation
+===============================
+
+a) transmission
+
+Each transmission can take place with a different configuration of the rf
+module. Therfore each application can set its own set of parameters. The driver
+takes care, that each transmission takes place with the parameterset of the
+application, that requests the transmission. To allow the transmission to take
+place in the background, a tx thread is introduced.
+The transfer of data from the main thread to the tx thread is realised by a
+kfifo. With each write request of an application, the passed in data and the
+corresponding parameter set gets written to the kfifo.
+On the other "side" of the kfifo, the tx thread continuously checks, whether the
+kfifo is empty. If not, it gets one set of config and data from the kfifo. If
+there is no receive request or the receiver is still waiting for something in
+the air, the rf module is set to standby, the parameters for transmission gets
+set, the hardware fifo of the rf chip gets preloaded and the transmission gets
+started. Upon hardware fifo threshold interrupt it gets reloaded, thus enabling
+much longer telegrams then hardware fifo size. If the telegram is send and there
+is more data available in the kfifo, the procedure is repeated. If not the
+transmission cycle ends.
+
+b) reception
+
+Since there is only one application allowed to receive data at a time, for
+reception there is only one configuration set.
+As soon as an application sets an request for receiving a telegram, the reception
+configuration set is written to the rf module and it gets set into receiving mode.
+Now the driver is waiting, that a predefined RSSI level (signal strength at the
+receiver) is reached. Until this hasn't happened, the reception can be
+interrupted by the transmission thread at any time to insert a transmission cycle.
+As soon as the predefined RSSI level is meat, a receiving cycle starts. Similar
+as described for the transmission cycle the read out of the hardware fifo is done
+dynamically. Upon each hardware fifo threshold interrupt, a portion of data gets
+read. So also for reception it is possible to receive more data then the hardware
+fifo can hold.
+
+
+Driver API
+==========
+
+The driver is currently implemented as a character device. Therefore it supports
+the calls open, ioctl, read, write and close.
+
+
+params for ioctl
+----------------
+
+There are four options:
+PI433_IOC_RD_TX_CFG - get the transmission parameters from the driver
+PI433_IOC_WR_TX_CFG - set the transmission parameters
+PI433_IOC_RD_RX_CFG - get the receiving parameters from the driver
+PI433_IOC_WR_RX_CFG - set the receiving parameters
+
+The tx configuration is transfered via struct pi433_tx_cfg, the parameterset for transmission.
+It is devided into two sections: rf parameters and packet format.
+
+rf params:
+	frequency
+		frequency used for transmission.
+		Allowed values: 433050000...434790000
+	bit_rate
+		bit rate used for transmission.
+		Allowed values: #####
+	dev_frequency
+		frequency deviation in case of FSK.
+		Allowed values: 600...500000
+	modulation
+		FSK - frequency shift key
+		OOK - On-Off-key
+	modShaping
+		shapingOff	- no shaping

+		ramp40		- amp ramps up in 40us
+		ramp31		- amp ramps up in 31us
+		ramp25		- amp ramps up in 25us
+		ramp20		- amp ramps up in 20us

+	tx_start_condition
+		fifoLevel	- transmission starts, if fifo is filled to
+				  threshold level
+		fifoNotEmpty	- transmission starts, as soon as there is one
+				  byte in internal fifo
+	repetitions
+		This gives the option, to send a telegram multiple times. Default: 1
+
+packet format:
+	enable_preamble
+		optionOn	- a preamble will be automatically generated
+		optionOff	- no preamble will be generated
+	enable_sync
+		optionOn	- a sync word will be automatically added to
+				  the telegram after preamble
+		optionOff	- no sync word will be added
+		Attention: While possible to generate sync without preamble, the
+		receiver won't be able to detect the sync without preamble.
+	enable_length_byte
+		optionOn	- the length of the telegram will be automatically
+				  added to the telegram. It's part of the payload
+		optionOff	- no length information will be automatically added
+				  to the telegram.

+		Attention: should be used in combination with sync, only
+	enable_address_byte
+		optionOn	- the address byte will be automatically added to the
+				  telgram. It's part of the payload
+		optionOff	- the address byte will not be added to the telegram.

+		given by the buffer, passed in with the write command. Will be
+		ignored if set to zero.
+	sync_pattern[8]
+		contains up to eight values, that are used as the sync pattern
+		on sync option
+	address_byte
+		one byte, used as address byte on address byte option.
+
+
+The rx configuration is transfered via struct pi433_rx_cfg, the parameterset for receiving. It is devided into two sections: rf parameters and packet format.
+
+rf params:
+	frequency
+		frequency used for transmission.
+		Allowed values: 433050000...434790000

+		If this value is exeeded, a reception cycle starts
+		Allowed values: 0...255
+	thresholdDecrement
+		in order to adapt to different levels of singnal strength, over
+		time the receiver gets more and more sensitive. This value
+		determs, how fast the sensitivity increases.

+		needed, if a telegram of a third party device should be received,
+		using a protocol not compatible with the packet engine of the rf69 chip.
+	sync_pattern[8]
+		contains up to eight values, that are used as the sync pattern
+		on sync option.
+		This setting must meet the configuration of the transmitting device,
+		if sync option is enabled.
+	node_address
+		one byte, used as node address byte on address byte option.

+ * It is based on the HopeRf Module RFM69CW. Therefore inside of this
+ * driver, you'll find an abstraction of the rf69 chip.
+ *
+ * If needed, this driver could be extended, to also support other
+ * devices, basing on HopeRfs rf69.
+ *
+ * The driver can also be extended, to support other modules of
+ * HopeRf with a similar interace - e. g. RFM69HCW, RFM12, RFM95, ...

+ * If needed, this driver could be extended, to also support other
+ * devices, basing on HopeRfs rf69.
+ *
+ * The driver can also be extended, to support other modules of
