This patch adds V4L2 sub-device driver for OV2680 image sensor.
The OV2680 is a 1/5" CMOS color sensor from Omnivision.
Supports output format: 10-bit Raw RGB.
The OV2680 has a single lane MIPI interface.
The driver exposes following V4L2 controls:
- auto/manual exposure,
- exposure,
- auto/manual gain,
- gain,
- horizontal/vertical flip,
- test pattern menu.
Supported resolution are only: QUXGA, 720P, UXGA.

The ADV7180 and ADV7182 transmit whole fields, bottom field followed
by top (or vice-versa, depending on detected video standard). So
for chips that do not have support for explicitly setting the field
mode via I2P, set the field mode to V4L2_FIELD_ALTERNATE.
I2P converts fields into frames using an edge adaptive algorithm. The
frame rate is the same as the 'field rate': e.g. X fields per second
are now X frames per second.

The use of 'DTV' is very confusing since it normally refers to Digital
TV e.g. DVB etc.
Instead use 'DV' (Digital Video), which nicely corresponds to the
DV Timings API used to configure such receivers and transmitters.
We keep an alias to avoid breaking userspace applications.
Since this alias is only available if __KERNEL__ is *not* defined
(i.e. it is only available for userspace, not kernelspace), any
drivers that use it also have to be converted to the new define.

Data about the implemented readout modes is partially stored in
imx274_formats[], the rest is scattered in several arrays. The latter
are then accessed using the mode index, e.g.:
min_frame_len[priv->mode_index]
Consolidate all these data in imx274_formats[], and store a pointer to
the selected mode (i.e. imx274_formats[priv->mode_index]) in the main
device struct. This way code to use these data becomes more readable,
e.g.:
priv->mode->min_frame_len
This removes lots of scaffolding code and keeps data about each mode
in a unique place.
Also remove a parameter to imx274_mode_regs() that is now unused.
While this adds the mode pointer to the device struct, it does not
remove the mode_index from it because mode_index is still used in two
dev_dbg() calls. This will be handled in a follow-up commit.

The current probe function calls v4l2_ctrl_handler_setup() before
initializing the format info. This triggers call paths such as:
imx274_probe -> v4l2_ctrl_handler_setup -> imx274_s_ctrl ->
imx274_set_exposure, where priv->mode_index is accessed before being
assigned.
This is wrong but does not trigger a visible bug because priv is
zero-initialized and 0 is the default value for priv->mode_index. But
this would become a crash in follow-up commits when mode_index is
replaced by a pointer that must always be valid.
Fix the bug before it shows up by initializing struct members early.

Add a v4l2 sub-device driver for the ak7375 lens voice coil.
This is a voice coil module using the i2c bus to control the
focus position.
ak7375 can write multiple bytes of data at a time. If more
data is received instead of the stop condition after receiving
one byte of data, the address inside the chip is automatically
incremented and the data is written into the next address.
The ak7375 can control the position with 12 bits value and
consists of two 8 bit registers show as below:
register 0x00(AK7375_REG_POSITION):
+---+---+---+---+---+---+---+---+
|D11|D10|D09|D08|D07|D06|D05|D04|
+---+---+---+---+---+---+---+---+
register 0x01:
+---+---+---+---+---+---+---+---+
|D03|D02|D01|D00|---|---|---|---|
+---+---+---+---+---+---+---+---+
This driver support :
- set ak7375 to standby mode once suspend and
turn it back to active if resume
- set the position via V4L2_CID_FOCUS_ABSOLUTE ctrl

The banding filter ON/OFF is controlled via bit 5 of COM8 register. It
is attempted to be enabled in ov772x_set_params() by the following line.
ret = ov772x_mask_set(client, COM8, BNDF_ON_OFF, 1);
But this unexpectedly results disabling the banding filter, because the
mask and set bits are exclusive.
On the other hand, ov772x_s_ctrl() correctly sets the bit by:
ret = ov772x_mask_set(client, COM8, BNDF_ON_OFF, BNDF_ON_OFF);
The same fix was already applied to non-soc_camera version of ov772x

The ov772x driver provides three V4L2 controls and the current value of
each control is saved as a variable in the private data structure.
We don't need to keep track of the current value by ourself, if we use
v4l2_ctrl returned from v4l2_ctrl_new_std() instead.
This is a preparatory change to avoid accessing registers under power
saving mode. This simplifies s_ctrl() by making it just return without
saving the current control value in private area when it is called under
power saving mode.

video (i.e: field is V4L2_FIELD_ALTERNATE) the height refers to the number
of lines in the field and not the number of lines in the full frame (which
is twice the field height for interlaced formats).
So the original height calculation was correct, and it shouldn't had been
