At least on NVT6779D clearing the wake fifo works in learning mode only
(although this condition is not mentioned in the chip spec).
Setting the clear fifo bit has no effect in wake up mode.
Even if clearing the wake fifo should work in wake up mode on other
chips this workaround doesn't hurt.
If needed the caller of nvt_clear_cir_wake_fifo has to take care
of locking.

The two EFM ioports are accessed by drivers for other parts of the Nuvoton
Super-IO chips too. Therefore access to these ioports needs to be
protected by using request_muxed_region (like it's implemented e.g. in
hwmon/nct6775 already).

The ov2659 driver performs device detection and initialization in the
following way:
- send reset command REG_SOFTWARE_RESET
- load array of predefined register's setting (~150 values)
- read device version REG_SC_CHIP_ID_H/REG_SC_CHIP_ID_L
- check version and exit if invalid.
As result, for not connected device there will be >~150 i2c transactions
executed before device version checking and exit (there are no
failures detected because ov2659 declared as I2C_CLIENT_SCCB and NACKs
are ignored in this case).
Let's fix that by checking the chip version first and start
initialization only if it's supported.

The data type "int" was used by the variable "ret" in the
gsc_m2m_poll() function despite of the aspect that the type "unsigned int"
will usually be needed for the return value from a call of the

Passing a physical address to free_pages() is a bad idea.
config_params->fault_pxl.fpc_table_addr is set to virt_to_phys()
of __get_free_pages() return value; what we should pass to free_pages()
is its phys_to_virt(). ccdc_close() does that properly, but

changeset 460b6c0831cb ("tvp5150: Add s_stream subdev operation
support") broke for em28xx-based devices with uses tvp5150. On those
devices, touching the TVP5150_MISC_CTL register causes em28xx to stop
streaming.
I suspect that it uses the 27 MHz clock provided by tvp5150 to feed
em28xx. So, change the logic to do nothing on s_stream if the tvp5150 is
not set up to work with V4L2_MBUS_PARALLEL.
Tested with Hauppauge WinTV USB 2 model 42012 Rev. C186

The FIFO is used for ir_raw_event records, however for some historic
reason the FIFO is used on a per byte basis. IMHO this adds unneeded
complexity. Therefore set up the FIFO for ir_raw_event records.
This also allows to define the FIFO statically as part of
ir_raw_event_ctrl instead of having to allocate the FIFO dynamically.
In addition:
- When writing into the FIFO and it's full return ENOSPC instead of
ENOMEM thus making it easier to tell between "FIFO full" and
"Dynamic memory allocation failed" when the error is propagated to
a higher level.
Also add an error message.
- When reading from the FIFO check whether it's empty.
This is not strictly needed here but kfifo_out is annotated
"must check" anyway.
Successfully tested it with the nuvoton-cir driver.

After power-up, the tvp5150 decoder is in a unknown state until the
RESETB pin is driven LOW which reset all the registers and restarts
the chip's internal state machine.
The init sequence has some timing constraints and the RESETB signal
can only be used if the PDN (Power-down) pin is first released.
So, the initialization sequence is as follows:
1- PDN (active-low) is driven HIGH so the chip is power-up
2- A 20 ms delay is needed before sending a RESETB (active-low) signal.
3- The RESETB pulse duration is 500 ns.
4- A 200 us delay is needed for the I2C client to be active after reset.

Pull GPIO updates from Linus Walleij:
"Here is the bulk of GPIO changes for v4.5.
Notably there are big refactorings mostly by myself, aimed at getting
the gpio_chip into a shape that makes me believe I can proceed to
preserve state for a proper userspace ABI (character device) that has
already been proposed once, but resulted in the feedback that I need
to go back and restructure stuff. So I've been restructuring stuff.
On the way I ran into brokenness (return code from the get_value()
callback) and had to fix it. Also, refactored generic GPIO to be
simpler.
Some of that is still waiting to trickle down from the subsystems all
over the kernel that provide random gpio_chips, I've touched every
single GPIO driver in the kernel now, oh man I didn't know I was
responsible for so much...
Apart from that we're churning along as usual.
I took some effort to test and retest so it should merge nicely and we
shook out a couple of bugs in -next.
Infrastructural changes:
- In struct gpio_chip, rename the .dev node to .parent to better
reflect the fact that this is not the GPIO struct device
abstraction. We will add that soon so this would be totallt
confusing.
- It was noted that the driver .get_value() callbacks was sometimes
reporting negative -ERR values to the gpiolib core, expecting them
to be propagated to consumer gpiod_get_value() and gpio_get_value()
calls. This was not happening, so as there was a mess of drivers
returning negative errors and some returning "anything else than
zero" to indicate that a line was active. As some would have bit
31 set to indicate "line active" it clashed with negative error
codes. This is fixed by the largeish series clamping values in all
drivers with !!value to [0,1] and then augmenting the code to
propagate error codes to consumers. (Includes some ACKed patches
in other subsystems.)
- Add a void *data pointer to struct gpio_chip. The container_of()
design pattern is indeed very nice, but we want to reform the
struct gpio_chip to be a non-volative, stateless business, and keep
states internal to the gpiolib to be able to hold on to the state
when adding a proper userspace ABI (character device) further down
the road. To achieve this, drivers need a handle at the internal
state that is not dependent on their struct gpio_chip() so we add
gpiochip_add_data() and gpiochip_get_data() following the pattern
of many other subsystems. All the "use gpiochip data pointer"
patches transforms drivers to this scheme.
- The Generic GPIO chip header has been merged into the general
<linux/gpio/driver.h> header, and the custom header for that
removed. Instead of having a separate mm_gpio_chip struct for
these generic drivers, merge that into struct gpio_chip,
simplifying the code and removing the need for separate and
confusing includes.
Misc improvements:
- Stabilize the way GPIOs are looked up from the ACPI legacy
specification.
- Incremental driver features for PXA, PCA953X, Lantiq (patches from
the OpenWRT community), RCAR, Zynq, PL061, 104-idi-48
New drivers:
- Add a GPIO chip to the ALSA SoC AC97 driver.
- Add a new Broadcom NSP SoC driver (this lands in the pinctrl dir,
but the branch is merged here too to account for infrastructural
changes).
- The sx150x driver now supports the sx1502"

controller next generation patches, with is the result of one year of
discussions and development. It also contains patches to enable media
controller support at the DVB subsystem.
The goal is to improve the media controller to allow proper support
for other types of Video4Linux devices (radio and TV ones) and to
extend the media controller functionality to allow it to be used by
other subsystems like DVB, ALSA and IIO.
In order to use the new functionality, a new ioctl is needed
(MEDIA_IOC_G_TOPOLOGY). As we're still discussing how to pack the
struct fields of this ioctl in order to avoid compat32 issues, I
decided to add a patch at the end of this series commenting out the
new ioctl, in order to postpone the addition of the new ioctl to the
next Kernel version (4.6).
With that, no userspace visible changes should happen at the media
controller API, as the existing ioctls are untouched. Yet, it helps
DVB, ALSA and IIO developers to develop and test the patches adding
media controller support there, as the core will contain all required
internal changes to allow adding support for devices that belong to
those subsystems"

Pull media updates from Mauro Carvalho Chehab:
"The part of patches for Kernel 4.5. There's nothing really big here:
- driver-specific headers for media devices were moved to separate
directories, in order to make clear what headers belong to the core
kABI and require documentation
- Platform data for media drivers were moved from include/media to
include/linux/platform_data/media
- add a driver for cs3308 8-channel volume control, used on some
high-end capture boards
- lirc.h kAPI header were added at include/uapi/linux
- Driver cleanups, new board additions and improvements"

There are a few discussions left with regards to this ioctl:
1) the name of the new structs will contain _v2_ on it?
2) what's the best alternative to avoid compat32 issues?
Due to that, let's postpone the addition of this new ioctl to
the next Kernel version, to give people more time to discuss it.

While mxl111sf may have multiple frontends, it has just one
tuner. Reflect that on the media graph.

Devices like mxl111sf-based WinTV Aero-m have multiple
frontends, all linked on the same demod. Currently, the
dvb_create_graph() function is not smart enough to create
multiple links. Fix it.
