2780168859 [media] OMAP_VOUT: CLEANUP: Remove redundant code from omap_vout_isr
Currently, there is a lot of redundant code is between DPI and VENC panels, this
can be made common by moving out field/interlace specific code to a separate
function called omapvid_handle_interlace_display(). There is no functional
change made.

d06db7ec90 [media] OMAP_VOUT: Fix check in reqbuf for buf_size allocation
The commit 383e4f6987 makes reqbuf prevent
requesting a larger size buffer than what is allocated at kernel boot during
omap_vout_probe.

In omap_vout_buffer_setup callback API, the requested size is compared with
vout->buffer_size, this isn't correct as vout->buffer_size is later set to the
size requested in reqbuf. When the video device is opened the next time, this
check will prevent us to allocate a buffer which is larger than what we requested
the last time.

Don't use vout->buffer_size, always check with the parameters video1_bufsize
or video2_bufsize.

If "i" is 2 then when we call cx25821_video_mux() we'd end up going
past the end of the cx25821_boards[dev->board]->input[].

The INPUT() macro obfuscates what's going on in that function so it's
a bit hard to follow.  And as Mauro points out the hard coded 2 is
not very helpful.

The Kconfig symbol RADIO_TEA5764_XTAL is unused. The code does use a
RADIO_TEA5764_XTAL macro, but does that rather peculiar. But there seems
to be a way to keep both. (The easiest way out would be to rip out both
the Kconfig symbol and the macro.)

Note there's also a module parameter 'use_xtal' to influence all this.

V4L2_CID_POWER_LINE_FREQUENCY control allows applications to instruct
a driver what is the power line frequency so an appropriate filter
can be used by the device to cancel flicker by compensating the light
intensity ripple. Currently in the menu we have entries for 50 Hz and
60 Hz and for entirely disabling the anti-flicker filter.
However some devices are capable of automatically detecting the
frequency, so add V4L2_CID_POWER_LINE_FREQUENCY_AUTO entry for them.

2f0babb7e4 [media] V4L: soc-camera: make (almost) all client drivers re-usable outside of the framework
The most important change in this patch is direct linking to struct
soc_camera_link via the client->dev.platform_data pointer. This makes most
of the soc-camera client drivers also usable outside of the soc-camera
framework. After this change all what is needed for these drivers to
function are inclusions of soc-camera headers for some convenience macros,
suitably configured platform data, which is anyway always required, and
loaded soc-camera core module for library functions. If desired, these
library functions can be made generic in the future and moved to a more
neutral location.

The only two client drivers, that still depend on soc-camera are:

mt9t031: it uses struct video_device for its PM. Since no hardware is
available, alternative methods cannot be tested.

ov6650: it uses struct soc_camera_device to pass its sense data back to
the bridge driver. A generic v4l2-subdevice approach should be developed
to perform this.

7b9d8c3c4c [media] V4L: soc-camera: call subdevice .s_power() method, when powering up or down
Currently soc-camera can use power regulators and platform specific
methods to power clients up and down. Additionally, client drivers can
provide their own subdevice .s_power() methods, acting directly on the
device. This patch adds calls to this method, when external power
supplies are on.

fff96b6685 [media] V4L: soc_camera_platform: do not leave dangling invalid pointers
The life-time of soc-camera device objects can be longer, than the
time, it is attached to a client driver, therefore all references to
the driver own data have to be cleared, when the driver is detached.
