+	  the GPU, we allow the innocent contexts also on the system to quiesce.
+	  It is then less likely for a hanging context to cause collateral
+	  damage as the system is reset in order to recover. The corollary is
+	  that the reset itself may take longer and so be more disruptive to
+	  interactive or low latency workloads.

+	default 1 # milliseconds
+	help
+	  When two user batches of equal priority are executing, we will
+	  alternate execution of each batch to ensure forward progress of
+	  all users. This is necessary in some cases where there may be
+	  an implicit dependency between those batches that requires
+	  concurrent execution in order for them to proceed, e.g. they
+	  interact with each other via userspace semaphores. Each context
+	  is scheduled for execution for the timeslice duration, before
+	  switching to the next context.
+
+	  May be 0 to disable timeslicing.

+/**
+ * DOC: RC6
+ *
+ * RC6 is a special power stage which allows the GPU to enter an very
+ * low-voltage mode when idle, using down to 0V while at this stage.  This
+ * stage is entered automatically when the GPU is idle when RC6 support is
+ * enabled, and as soon as new workload arises GPU wakes up automatically as
+ * well.
+ *
+ * There are different RC6 modes available in Intel GPU, which differentiate
+ * among each other with the latency required to enter and leave RC6 and
+ * voltage consumed by the GPU in different states.
+ *
+ * The combination of the following flags define which states GPU is allowed
+ * to enter, while RC6 is the normal RC6 state, RC6p is the deep RC6, and
+ * RC6pp is deepest RC6. Their support by hardware varies according to the
+ * GPU, BIOS, chipset and platform. RC6 is usually the safest one and the one
+ * which brings the most power savings; deeper states save more power, but
+ * require higher latency to switch to and wake up.

+/**
+ * DOC: GuC
+ *
+ * The GuC is a microcontroller inside the GT HW, introduced in gen9. The GuC is
+ * designed to offload some of the functionality usually performed by the host
+ * driver; currently the main operations it can take care of are:
+ *
+ * - Authentication of the HuC, which is required to fully enable HuC usage.
+ * - Low latency graphics context scheduling (a.k.a. GuC submission).
+ * - GT Power management.
+ *
+ * The enable_guc module parameter can be used to select which of those
+ * operations to enable within GuC. Note that not all the operations are
+ * supported on all gen9+ platforms.
+ *
+ * Enabling the GuC is not mandatory and therefore the firmware is only loaded
+ * if at least one of the operations is selected. However, not loading the GuC
+ * might result in the loss of some features that do require the GuC (currently
+ * just the HuC, but more are expected to land in the future).

- * DOC: HuC Firmware
- *
- * Motivation:
- * GEN9 introduces a new dedicated firmware for usage in media HEVC (High
- * Efficiency Video Coding) operations. Userspace can use the firmware
- * capabilities by adding HuC specific commands to batch buffers.
- *
- * Implementation:
- * The same firmware loader is used as the GuC. However, the actual
- * loading to HW is deferred until GEM initialization is done.
- *
- * Note that HuC firmware loading must be done before GuC loading.

-/**
- * DOC: RC6
- *
- * RC6 is a special power stage which allows the GPU to enter an very
- * low-voltage mode when idle, using down to 0V while at this stage.  This
- * stage is entered automatically when the GPU is idle when RC6 support is
- * enabled, and as soon as new workload arises GPU wakes up automatically as well.
- *
- * There are different RC6 modes available in Intel GPU, which differentiate
- * among each other with the latency required to enter and leave RC6 and
- * voltage consumed by the GPU in different states.
- *
- * The combination of the following flags define which states GPU is allowed
- * to enter, while RC6 is the normal RC6 state, RC6p is the deep RC6, and
- * RC6pp is deepest RC6. Their support by hardware varies according to the
- * GPU, BIOS, chipset and platform. RC6 is usually the safest one and the one
- * which brings the most power savings; deeper states save more power, but
- * require higher latency to switch to and wake up.

+	 *    practice since Rockchip PLLs are controlled by tables and
+	 *    even if there is a divider in the middle I wouldn't expect PLL
+	 *    rates in the table that are just a few kHz different.
+	 *
+	 * 2. Get the clock framework to round the rate for us to tell us

+	 * likely to be allocated beyond the 32-bit boundary if sufficient
+	 * system memory is available. This is problematic on earlier Tegra
+	 * generations where host1x supports a maximum of 32 address bits in
+	 * the GATHER opcode. In this case, unless host1x is behind an IOMMU
+	 * as well it won't be able to process buffers allocated beyond the
+	 * 32-bit boundary.
+	 *
+	 * The DMA API will use bounce buffers in this case, so that could
+	 * perhaps still be made to work, even if less efficient, but there
+	 * is another catch: in order to perform cache maintenance on pages
+	 * allocated for discontiguous buffers we need to map and unmap the
+	 * SG table representing these buffers. This is fine for something
+	 * small like a push buffer, but it exhausts the bounce buffer pool
+	 * (typically on the order of a few MiB) for framebuffers (many MiB
+	 * for any modern resolution).
+	 *
+	 * Work around this by making sure that Tegra DRM clients only use
+	 * an IOMMU if the parent host1x also uses an IOMMU.
+	 *
+	 * Note that there's still a small gap here that we don't cover: if
+	 * the DMA API is backed by an IOMMU there's no way to control which
+	 * device is attached to an IOMMU and which isn't, except via wiring
+	 * up the device tree appropriately. This is considered an problem
+	 * of integration, so care must be taken for the DT to be consistent.

+ * AB8500 General Purpose ADC driver. The AB8500 uses reference voltages:

+ * battery voltages, AC (mains) voltage, USB cable voltage, as well as voltages
+ * representing the temperature of the chip die and battery, accessory
+ * detection by resistance measurements using relative voltages and GSM burst
+ * information.
+ *
+ * Some of the voltages are measured on external pins on the IC, such as
+ * battery temperature or "ADC aux" 1 and 2. Other voltages are internal rails
+ * from other parts of the ASIC such as main charger voltage, main and battery
+ * backup voltage or USB VBUS voltage. For this reason drivers for other
+ * parts of the system are required to obtain handles to the ADC to do work
+ * for them and the IIO driver provides arbitration among these consumers.

+ * Some PHY devices need to know what the actual card clock is.  In order for

+ * for them to query.
+ *
+ * Note: without seriously re-architecting SDHCI's clock code and testing on
+ * all platforms, there's no way to create a totally beautiful clock here
+ * with all clock ops implemented.  Instead, we'll just create a clock that can
+ * be queried and set the CLK_GET_RATE_NOCACHE attribute to tell common clock
+ * framework that we're doing things behind its back.  This should be sufficient
+ * to create nice clean device tree bindings and later (if needed) we can try
+ * re-architecting SDHCI if we see some benefit to it.
+ *
+ * @sdhci_arasan:	Our private data structure.
+ * @clk_xin:		Pointer to the functional clock
+ * @dev:		Pointer to our struct device.

+/* The schedule engine and the PTP clock are driven by the same oscillator, and

+ * time-of-day, the schedule engine is only running in 'ticks' (25 ticks make
+ * up a delta, which is 200ns), and wrapping around at the end of each cycle.
+ * The schedule engine is started when the PTP clock reaches the PTPSCHTM time
+ * (in PTP domain).
+ * Because the PTP clock can be rate-corrected (accelerated or slowed down) by
+ * a software servo, and the schedule engine clock runs in parallel to the PTP
+ * clock, there is logic internal to the switch that periodically keeps the
+ * schedule engine from drifting away. The frequency with which this internal
+ * syntonization happens is the PTP clock correction period (PTPCLKCORP). It is
+ * a value also in the PTP clock domain, and is also rate-corrected.
+ * To be precise, during a correction period, there is logic to determine by
+ * how many scheduler clock ticks has the PTP clock drifted. At the end of each
+ * correction period/beginning of new one, the length of a delta is shrunk or
+ * expanded with an integer number of ticks, compared with the typical 25.
+ * So a delta lasts for 200ns (or 25 ticks) only on average.
+ * Sometimes it is longer, sometimes it is shorter. The internal syntonization
+ * logic can adjust for at most 5 ticks each 20 ticks.
+ *
+ * The first implication is that you should choose your schedule correction
+ * period to be an integer multiple of the schedule length. Preferably one.
+ * In case there are schedules of multiple ports active, then the correction
+ * period needs to be a multiple of them all. Given the restriction that the
+ * cycle times have to be multiples of one another anyway, this means the
+ * correction period can simply be the largest cycle time, hence the current
+ * choice. This way, the updates are always synchronous to the transmission
+ * cycle, and therefore predictable.
+ *
+ * The second implication is that at the beginning of a correction period, the
+ * first few deltas will be modulated in time, until the schedule engine is
+ * properly phase-aligned with the PTP clock. For this reason, you should place
+ * your best-effort traffic at the beginning of a cycle, and your
+ * time-triggered traffic afterwards.
+ *
+ * The third implication is that once the schedule engine is started, it can
+ * only adjust for so much drift within a correction period. In the servo you
+ * can only change the PTPCLKRATE, but not step the clock (PTPCLKADD). If you
+ * want to do the latter, you need to stop and restart the schedule engine,
+ * which is what the state machine handles.

 ffsSetAttr() is just dangling in the breeze, not wired up at all...

+Convert global mutexes to a per-superblock mutex.

+exfat_remount does exactly one thing.  Fix to actually deal with remount
+options, particularly handling R/O correctly.  For that matter, allow

+		with  the arrows, or backspacing etc. speakup says the incorrect
+		characters. Set this to a higher value to adjust for the delay
+		and better synchronisation between cursor position and speech.

+What:		/sys/accessibility/speakup/keymap
+KernelVersion:	2.6
+Contact:	speakup@linux-speakup.org
+Description:	Speakup keymap remaps keys to Speakup functions.
+		It uses a binary

+		textual  keymap into the binary format which is then loaded into
+		/sys/accessibility/speakup/keymap.
+
+What:		/sys/accessibility/speakup/no_interrupt
+KernelVersion:	2.6
+Contact:	speakup@linux-speakup.org
+Description:	Controls if typing interrupts output from speakup. With

+		speakup if for example
+		the say screen command is used before the
+		entire screen  is read.
+		With no_interrupt set to one, if the say

+
+What:		/sys/accessibility/speakup/punc_level
+KernelVersion:	2.6
+Contact:	speakup@linux-speakup.org
+Description:	Controls the level of punctuation spoken as the screen is
+		displayed, not reviewed. Levels range from zero no punctuation,
+		to four, all punctuation. One corresponds to punc_some, two
+		corresponds to punc_most, and three as well as four both
+		correspond to punc_all. Some hardware synthesizers may have
+		different levels each corresponding to  three and four for
+		punc_level. Also note that if punc_level is set to zero, and
+		key_echo is set to one, typed punctuation is still spoken as it
+		is typed.
+
+What:		/sys/accessibility/speakup/punc_most

+
+What:		/sys/accessibility/speakup/reading_punc
+KernelVersion:	2.6
+Contact:	speakup@linux-speakup.org
+Description:	Almost the same as punc_level, the differences being that
+		reading_punc controls the level of punctuation when reviewing
+		the screen with speakup's screen review commands. The other
+		difference is that reading_punc set to three speaks punc_all,
+		and reading_punc set to four speaks all punctuation, including
+		spaces.
+
+What:		/sys/accessibility/speakup/repeats
+KernelVersion:	2.6
+Contact:	speakup@linux-speakup.org
+Description:	A list of characters speakup repeats. Normally, when there are
+		more than three characters in a row, speakup
+		just reads three of
+		those characters. For example, "......" would be read as dot,
+		dot, dot. If a . is added to the list of characters in repeats,
+		"......" would be read as dot, dot, dot, times six.
+
+What:		/sys/accessibility/speakup/say_control
+KernelVersion:	2.6
+Contact:	speakup@linux-speakup.org
+Description:	If set to one, speakup speaks shift, alt and control when those

+
+What:		/sys/accessibility/speakup/synth
+KernelVersion:	2.6
+Contact:	speakup@linux-speakup.org
+Description:	Gets or sets the synthesizer driver currently in use. Reading
+		synth returns the synthesizer driver currently in use. Writing
+		synth switches to the given synthesizer driver, provided it is
+		either built into the kernel, or already loaded as a module.
+
+What:		/sys/accessibility/speakup/synth_direct
+KernelVersion:	2.6
+Contact:	speakup@linux-speakup.org
+Description:	Sends whatever is written to synth_direct
+		directly to the speech synthesizer in use, bypassing speakup.
+		This could be used to make the synthesizer speak
+		a string, or to
+		send control sequences to the synthesizer to change how the
+		synthesizer behaves.

+What:		/sys/accessibility/speakup/i18n/ctl_keys
+KernelVersion:	2.6
+Contact:	speakup@linux-speakup.org
+Description:	Here, you will find names of control keys.  These are used with
+		Speakup's say_control feature.
+
+What:		/sys/accessibility/speakup/i18n/function_names
+KernelVersion:	2.6
+Contact:	speakup@linux-speakup.org
+Description:	Here, you will find a list of names for Speakup functions.
+		These are used by the help system.  For example, suppose that
+		you have activated help mode, and you pressed
+		keypad 3.  Speakup
+		says: "keypad 3 is character, say next."
+		The message "character, say next" names a Speakup function, and
+		it comes from this function_names file.
+
+What:		/sys/accessibility/speakup/i18n/states
+KernelVersion:	2.6
+Contact:	speakup@linux-speakup.org
+Description:	This file contains names for key states.
+		Again, these are part of the help system.  For instance, if you
+		had pressed speakup + keypad 3, you would hear:
+		"speakup keypad 3 is go to bottom edge."
+		The speakup key is depressed, so the name of the key state is
+		speakup.
+		This part of the message comes from the states collection.
+
+What:		/sys/accessibility/speakup/i18n/characters
+KernelVersion:	2.6
+Contact:	speakup@linux-speakup.org
+Description:	Through this sys entry, Speakup gives you the ability to change
+		how Speakup pronounces a given character. You could, for
+		example, change how some punctuation characters are spoken. You
+		can even change how Speakup will pronounce certain letters. For
+		further details see '12.  Changing the Pronunciation of
+		Characters' in Speakup User's Guide (file spkguide.txt in
+		source).
+
+What:		/sys/accessibility/speakup/i18n/colors
+KernelVersion:	2.6
+Contact:	speakup@linux-speakup.org
+Description:	When you use the "say attributes" function, Speakup says the
+		name of the foreground and background colors.  These names come
+		from the i18n/colors file.
+
+What:		/sys/accessibility/speakup/i18n/formatted
+KernelVersion:	2.6
+Contact:	speakup@linux-speakup.org
+Description:	This group of messages contains embedded formatting codes, to
+		specify the type and width of displayed data.  If you change
+		these, you must preserve all of the formatting codes, and they
+		must appear in the order used by the default messages.
+
+What:		/sys/accessibility/speakup/i18n/key_names
+KernelVersion:	2.6
+Contact:	speakup@linux-speakup.org
+Description:	Again, key_names is used by Speakup's help system.  In the
+		previous example, Speakup said that you pressed "keypad 3."
+		This name came from the key_names file.
+
+What:		/sys/accessibility/speakup/<synth-name>/
+KernelVersion:	2.6
+Contact:	speakup@linux-speakup.org
+Description:	In `/sys/accessibility/speakup` is a directory corresponding to
+		the synthesizer driver currently in use (E.G) `soft` for the
+		soft driver. This directory contains files which control the
+		speech synthesizer itself,
+		as opposed to controlling the speakup
+		screen reader. The parameters in this directory have the same
+		names and functions across all
+		supported synthesizers. The range
+		of values for freq, pitch, rate, and vol is the same for all
+		supported synthesizers, with the given range being internally
+		mapped by the driver to  more or less fit the range of values
+		supported for a given parameter by the individual synthesizer.
+		Below is a description of values and  parameters for soft
+		synthesizer, which is currently the most commonly used.
+
+What:		/sys/accessibility/speakup/soft/caps_start
+KernelVersion:	2.6
+Contact:	speakup@linux-speakup.org
+Description:	This is the string that is sent to the synthesizer to cause it
+		to start speaking uppercase letters. For the soft synthesizer
+		and most others, this causes the pitch of the voice to rise
+		above the currently set pitch.
+
+What:		/sys/accessibility/speakup/soft/caps_stop
+KernelVersion:	2.6
+Contact:	speakup@linux-speakup.org
+Description:	This is the string sent to the synthesizer to cause it to stop
+		speaking uppercase letters. In the case of the soft synthesizer
+		and most others, this returns the pitch of the voice
+		down to the
+		currently set pitch.
+
+What:		/sys/accessibility/speakup/soft/delay_time
+KernelVersion:	2.6
+Contact:	speakup@linux-speakup.org
+Description:	TODO:
+
+What:		/sys/accessibility/speakup/soft/direct
+KernelVersion:	2.6
+Contact:	speakup@linux-speakup.org
+Description:	Controls if punctuation is spoken by speakup, or by the
+		synthesizer.
+		For example, speakup speaks ">" as "greater", while
+		the espeak synthesizer used by the soft driver speaks "greater
+		than". Zero lets speakup speak the punctuation. One lets the
+		synthesizer itself speak punctuation.
+
+What:		/sys/accessibility/speakup/soft/freq
+KernelVersion:	2.6
+Contact:	speakup@linux-speakup.org
+Description:	Gets or sets the frequency of the speech synthesizer. Range is
+		0-9.
+
+What:		/sys/accessibility/speakup/soft/full_time
+KernelVersion:	2.6
+Contact:	speakup@linux-speakup.org
+Description:	TODO:
+
+What:		/sys/accessibility/speakup/soft/jiffy_delta
+KernelVersion:	2.6
+Contact:	speakup@linux-speakup.org
+Description:	This controls how many jiffys the kernel gives to the
+		synthesizer. Setting this too high can make a system unstable,
+		or even crash it.
+
+What:		/sys/accessibility/speakup/soft/pitch
+KernelVersion:	2.6
+Contact:	speakup@linux-speakup.org
+Description:	Gets or sets the pitch of the synthesizer. The range is 0-9.
+
+What:		/sys/accessibility/speakup/soft/punct
+KernelVersion:	2.6
+Contact:	speakup@linux-speakup.org
+Description:	Gets or sets the amount of punctuation spoken by the
+		synthesizer. The range for the soft driver seems to be 0-2.
+		TODO: How is this related to speakup's punc_level, or
+		reading_punc.
+
+What:		/sys/accessibility/speakup/soft/rate
+KernelVersion:	2.6
+Contact:	speakup@linux-speakup.org
+Description:	Gets or sets the rate of the synthesizer. Range is from zero
+		slowest, to nine fastest.
+
+What:		/sys/accessibility/speakup/soft/tone
+KernelVersion:	2.6
+Contact:	speakup@linux-speakup.org
+Description:	Gets or sets the tone of the speech synthesizer. The range for
+		the soft driver seems to be 0-2. This seems to make no
+		difference if using espeak and the espeakup connector.
+		TODO: does espeakup support different tonalities?
+
+What:		/sys/accessibility/speakup/soft/trigger_time
+KernelVersion:	2.6
+Contact:	speakup@linux-speakup.org
+Description:	TODO:
+
+What:		/sys/accessibility/speakup/soft/voice
+KernelVersion:	2.6
+Contact:	speakup@linux-speakup.org
+Description:	Gets or sets the voice used by the synthesizer if the
+		synthesizer can speak in more than one voice. The range for the
+		soft driver is 0-7. Note that while espeak supports multiple
+		voices, this parameter will not set the voice when the espeakup
+		connector is used  between speakup and espeak.
+
+What:		/sys/accessibility/speakup/soft/vol
+KernelVersion:	2.6
+Contact:	speakup@linux-speakup.org
+Description:	Gets or sets the volume of the speech synthesizer. Range is 0-9,
+		with zero being the softest, and nine being the loudest.

+The WFxxx chip series can be connected via SPI or via SDIO.
+
+SPI
+---
+
+You have to declare the WFxxx chip in your device tree.
+
+Required properties:
+ - compatible: Should be "silabs,wfx-spi"
+ - reg: Chip select address of device
+ - spi-max-frequency: Maximum SPI clocking speed of device in Hz
+ - interrupts-extended: Should contain interrupt line (interrupt-parent +
+   interrupt can also been used). Trigger should be `IRQ_TYPE_EDGE_RISING`.
+
+Optional properties:
+ - reset-gpios: phandle of gpio that will be used to reset chip during probe.
+   Without this property, you may encounter issues with warm boot.
+
+Please consult Documentation/devicetree/bindings/spi/spi-bus.txt for optional
+SPI connection related properties,
+
+Example:
+
+&spi1 {
+	wfx {
+		compatible = "silabs,wfx-spi";
+		pinctrl-names = "default";
+		pinctrl-0 = <&wfx_irq &wfx_gpios>;
+		interrupts-extended = <&gpio 16 IRQ_TYPE_EDGE_RISING>;
+		wakeup-gpios = <&gpio 12 GPIO_ACTIVE_HIGH>;
+		reset-gpios = <&gpio 13 GPIO_ACTIVE_HIGH>;
+		reg = <0>;
+		spi-max-frequency = <42000000>;
+	};
+};
+
+
+SDIO
+----
+
+The driver is able to detect a WFxxx chip on SDIO bus by matching its Vendor ID
+and Product ID. However, driver will only provide limited features in this
+case. Thus declaring WFxxx chip in device tree is strongly recommended (and may
+become mandatory in the future).
+
+Required properties:
+ - compatible: Should be "silabs,wfx-sdio"
+ - reg: Should be 1
+
+In addition, it is recommended to declare a mmc-pwrseq on SDIO host above WFx.
+Without it, you may encounter issues with warm boot. mmc-pwrseq should be
+compatible with mmc-pwrseq-simple. Please consult
+Documentation/devicetree/bindings/mmc/mmc-pwrseq-simple.txt for more
+information.
+
+Example:
+
+/ {
+	wfx_pwrseq: wfx_pwrseq {
+		compatible = "mmc-pwrseq-simple";
+		pinctrl-names = "default";
+		pinctrl-0 = <&wfx_reset>;
+		reset-gpios = <&gpio 13 GPIO_ACTIVE_LOW>;
+	};
+};
+
+&mmc1 {
+	mmc-pwrseq = <&wfx_pwrseq>;
+	#address-size = <1>;
+	#size = <0>;
+
+	mmc@1 {
+		compatible = "silabs,wfx-sdio";
+		reg = <1>;
+		pinctrl-names = "default";
+		pinctrl-0 = <&wfx_wakeup>;
+		wakeup-gpios = <&gpio 12 GPIO_ACTIVE_HIGH>;
+	};
+};
+
+Note that #address-size and #size shoud already be defined in node mmc1, but it
+is rarely the case.
+
+Common properties
+-----------------
+
+Some properties are recognized either by SPI and SDIO versions:
+ - wakeup-gpios: phandle of gpio that will be used to wake-up chip. Without
+   this property, driver will disable most of power saving features.
+ - config-file: Use an alternative file as PDS. Default is `wf200.pds`. Only
+   necessary for development/debug purpose.
+ - slk_key: String representing hexadecimal value of secure link key to use.
+   Must contains 64 hexadecimal digits. Not supported in current version.
+
+WFx driver also supports `mac-address` and `local-mac-address` as described in
+Documentation/devicetree/binding/net/ethernet.txt

+This is a list of things that need to be done to get this driver out of the
+staging directory.
+
+  - I have to take a decision about secure link support. I can:
+      - drop completely
+      - keep it in an external patch (my preferred option)
+      - replace call to mbedtls with kernel crypto API (necessitate a
+        bunch of work)
+      - pull mbedtls in kernel (non-realistic)
+
+  - mac80211 interface does not (yet) have expected quality to be placed
+    outside of staging:
+      - Some processings are redundant with mac80211 ones
+      - Many members from wfx_dev/wfx_vif can be retrieved from mac80211
+        structures
+      - Some functions are too complex

+ *
+ *          #undef xxx_name
+ *          #define xxx_name(msg) { msg, #msg },
