It is very similar than rc-msi-digivox-iii but new keytable is needed
as there is one existing scancode mapped to different button. Also that
one has less buttons.

Only enable this ioctl if the VIDEO_ADV_DEBUG config option is set. This
prevents abuse from both userspace and kernelspace (some bridge drivers
abuse DBG_G_CHIP_IDENT, lets prevent that from happening again with this
ioctl).

config looks like a hack that was added to tuner-core to allow some
configuration of TDA8290 tuner (it's not used by any other driver).
But with the new configuration options of tda8290 driver (no_i2c_gate
and std_map), it's no longer sufficient.
Change config to be void * instead, which allows passing tuner-dependent
config struct to drivers.
Also update saa7134 driver to reflect this change (no other driver uses this).

The FIMC-LITE output DMA allows to configure different YUV order
than the order at the camera input interface. Thus there is some
limited colorspace conversion possible. This patch makes the
color format variable be per FIMC-LITE input/output, rather than
a global per device. This also fixes incorrect behavior where
color format at the FIMC-LITE.N subdev's source pad is modified
by VIDIOC_S_FMT ioctl on the related video node.
YUV order definitions are corrected so that we use notation:
| byte3 | byte2 | byte1 | byte0

v4l2_of_parse_parallel_bus() function is now static and
EXPORT_SYMBOL() doesn't apply to it any more. Drop this
meaningless statement, which was supposed to be done in
the original merged patch.
While at it, edit the copyright notice so it is sorted in
both the v4l2-of.c and v4l2-of.h file in newest entries
on top order, and state clearly I'm just the author of

The sensor (I2C and/or SPI client) devices are instantiated by their
corresponding control bus drivers. Since the I2C client's master clock
is often provided by a video bus receiver (host interface) or other
than I2C/SPI controller device, the drivers of those client devices
are not accessing hardware in their driver's probe() callback. Instead,
after enabling clock, the host driver calls back into a sub-device
when it wants to activate them. This pattern is used by some in-tree
drivers and this patch also uses it for DT case. This patch is intended
as a first step for adding device tree support to the S5P/Exynos SoC
camera drivers. The second one is adding support for asynchronous
sub-devices registration and clock control from sub-device driver
level. The bindings shall not change when asynchronous probing support
is added.

This patch adds changes required for the main camera media device
driver corresponding to the top level 'camera' device node.
The drivers of devices corresponding to child nodes of the 'camera'
node are looked up and and registered as sub-devices to the top
level driver. The main driver's probing is deferred if any of the
sub-device drivers is not yet initialized and ready.

Simplify the debugging ioctls by creating the VIDIOC_DBG_G_CHIP_NAME ioctl.
This will eventually replace VIDIOC_DBG_G_CHIP_IDENT. Chip matching is done
by the name or index of subdevices or an index to a bridge chip. Most of this
can all be done automatically, so most drivers just need to provide get/set
register ops.
In particular, it is now possible to get/set subdev registers without
requiring assistance of the bridge driver.
