This is a preparation for a change to the type of v4l2 timestamps.
v4l2_get_timestamp() is a helper function that reads the monotonic
time and stores it into a 'struct timeval'. Multiple drivers implement
the same thing themselves for historic reasons.
Changing them all to use v4l2_get_timestamp() is more consistent
and reduces the amount of code duplication, and most importantly
simplifies the following changes.

The exynos4 fimc capture driver claims to use monotonic
timestamps but calls ktime_get_real_ts(). This is both
an incorrect API use, and a bad idea because of the y2038
problem and the fact that the wall clock time is not reliable
for timestamps across suspend or settimeofday().
This changes the driver to use the normal v4l2_get_timestamp()
function like all other drivers.

The V4L2_COLORSPACE_470_SYSTEM_M (aka NTSC 1953) colorspace has a different
whitepoint (C) compared to Rec. 709 (D65). The Bradford method is the
recommended method to compensate for that when converting a Rec. 709 color
to an NTSC 1953 color.
See http://www.brucelindbloom.com/index.html?Eqn_ChromAdapt.html for more
details on the Bradford method.
This patch updates the Rec. 709 to NTSC 1953 matrix so that it includes the
chromatic adaptation as calculated by the Bradford method, and it recalculates
the tpg_csc_colors table accordingly.

Every time compat32 encounters an unknown ioctl it will call pr_warn.
However, that's very irritating since it is perfectly normal that this
happens. For example, applications often try to call an ioctl to see if
it exists, and if that's used with an older kernel where compat32 doesn't
support that ioctl yet, then it starts spamming the kernel log.
So replace pr_warn by pr_debug.

rcar_vin_set_fmt() defaults to PAL when the subdevice's querystd() method call
fails (e.g. due to I2C error). This doesn't work very well when a camera being
used outputs NTSC which has different order of fields and resolution. Let us
stop pretending and return the actual error except when the querystd() method
is not implemented, in which case we'll have to set the 'field' variable to
V4L2_FIELD_NONE.

This change modifies gen_pool_get() and devm_gen_pool_create() client
interfaces adding one more argument "name" of a gen_pool object.
Due to implementation gen_pool_get() is capable to retrieve only one
gen_pool associated with a device even if multiple gen_pools are created,
fortunately right at the moment it is sufficient for the clients, hence
provide NULL as a valid argument on both producer devm_gen_pool_create()
and consumer gen_pool_get() sides.
Because only one created gen_pool per device is addressable, explicitly
add a restriction to devm_gen_pool_create() to create only one gen_pool
per device, this implies two possible error codes returned by the
function, account it on client side (only misc/sram). This completes
client side changes related to genalloc updates.

Core changes:
- Root out the wrapper devm_gpiod_get() and gpiod_get() etc
versions of the descriptor calls that did not use the flags
argument on the end. This was around for too long and eventually
Uwe Kleine-König took the time to clean it out and the last
users are removed along with the macros in this tag. In several
cases the use of flags simplifies the code. For this reason we
have (ACKed) patches hitting in DRM, IIO, media, NFC, USB+PHY
up until we hammer in the nail with removing the macros.
- Add a fat document describing how much ready-made GPIO stuff
we have i the kernel to discourage people from reinventing
a square wheel in userspace, as so often happens.
- Create a separate lockdep class for each instance of a GPIO
IRQ chip instead of using one class for all chips, as the current
code will not work with systems with several GPIO chips doing
lockdep debugging.
- Protect against driver unloading also when a GPIO line is only
used as IRQ for the GPIOLIB_IRQCHIP helpers.
- If the GPIO chip has no designated owner, assign the parent
device driver owner as owner.
- Consolidation of chained IRQ handler install/remove replacing
all call sites where irq_set_handler_data() and
irq_set_chained_handler() were done in succession with a
combined call to irq_set_chained_handler_and_data(). This
series was created by Thomas Gleixner after the problem was
observed by Russell King.
- Tglx also made another series of patches switching
__irq_set_handler_locked() for irq_set_handler_locked() which
is way cleaner.
- Tglx and Jiang Liu wrote a good bunch of patches to make use of
irq_desc_get_xxx() accessors and avoid looking up irq_descs
from IRQ numbers. The goal is to get rid of the irq number
from the handlers in the IRQ flow which is nice.
- Rob Herring killed off the set_irq_flags() for all GPIO
drivers. This was an ARM specific function that is replaced
with the generic irq_modify_status() where special flags
are actually needed.
- When an OF node has a pin range for its GPIOs, return
-EPROBE_DEFER if the pin controller isn't available.
Pretty logical, yet needed to be fixed.
- If a driver using GPIOLIB_IRQCHIP has its own
irq_*_resources call back, then call these instead of the
defaults provided by the GPIOLIB.
- Fix an undocumented ABI hole: named GPIOs were not
properly documented.
Driver improvements:
- Add get_direction() support to the generic GPIO driver, it's
strange that we didn't have that before.
- Make it possible to have input-only GPIO chips using the
generic GPIO driver.
- Clean out platform data support from the Emma Mobile (EM)
driver
- Finegrained runtime PM support for the RCAR driver.
- Support r8a7795 (R-car H3) in the RCAR driver.
- Support interrupts on GPIOs 16 thru 31 in the DaVinci driver.
- Some consolidation and new support in the MPC8xxx driver,
we now support MPC5125.
- Preempt-RT-friendly patches: the OMAP, MPC8xxx, drivers uses raw
spinlocks making it work better with the realime patches.
- Interrupt support for the EXTRAXFS GPIO driver.
- Make the ETRAXFS GPIO driver support also ARTPEC-3.
- Interrupt and wakeup support for the BRCMSTB driver, also for
wakeup from S5 cold boot.
- Mask MXC IRQs during suspend.
- Improve OMAP2 GPIO set_debounce() to work according to spec.
- The VF610 driver handles IRQs properly.
New drivers:
- ZTE ZX GPIO driver.

Merge tag 'gpio-v4.3-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio
Pull GPIO updates from Linus Walleij:
"This is the bulk of GPIO changes for the v4.3 kernel cycle.
There is quite a lot going on in the GPIO subsystem this merge window,
so the main matter is decribed below.
The hits in other subsystems when making the GPIO flags optional are
all ACKed by their respective subsystem maintainers.
Core changes:
- Root out the wrapper devm_gpiod_get() and gpiod_get() etc versions
of the descriptor calls that did not use the flags argument on the
end. This was around for too long and eventually Uwe Kleine-König
took the time to clean it out and the last users are removed along
with the macros in this tag. In several cases the use of flags
simplifies the code. For this reason we have (ACKed) patches
hitting in DRM, IIO, media, NFC, USB+PHY up until we hammer in the
nail with removing the macros.
- Add a fat document describing how much ready-made GPIO stuff we
have i the kernel to discourage people from reinventing a square
wheel in userspace, as so often happens.
- Create a separate lockdep class for each instance of a GPIO IRQ
chip instead of using one class for all chips, as the current code
will not work with systems with several GPIO chips doing lockdep
debugging.
- Protect against driver unloading also when a GPIO line is only used
as IRQ for the GPIOLIB_IRQCHIP helpers.
- If the GPIO chip has no designated owner, assign the parent device
driver owner as owner.
- Consolidation of chained IRQ handler install/remove replacing all
call sites where irq_set_handler_data() and
irq_set_chained_handler() were done in succession with a combined
call to irq_set_chained_handler_and_data().
This series was created by Thomas Gleixner after the problem was
observed by Russell King.
- Tglx also made another series of patches switching
__irq_set_handler_locked() for irq_set_handler_locked() which is

LIBELF_32 is not defined in Kconfig, and is left over legacy
which is not required in the upstream driver, so remove it.
