When updating the crop rectangle during streaming, the IRQ handler will
reprogram the resizer after the current frame. A race condition
currently exists between the set selection operation and the IRQ
handler: if the set selection operation is called twice in a row and the
IRQ handler runs only during the second call, it could reprogram the
hardware with partially updated values. Use a spinlock to protect
against that.

The resizer_set_input_size() function prints a debugging message with
the input width and height values. As the function is called from
interrupt context, printing that message to the serial console could
slow down the interrupt handler and cause it to miss the start of the
next frame, causing image corruption.
Fix this by reorganizing the resizer debug messages. The driver now
prints the input size, the crop rectangle and the output size in the set
selection handler instead of scattering debug messages in various
places.

In BT.656 mode the synchronization signals are generated by the CCDC
from the embedded sync codes. The VD0 and VD1 interrupts are thus only
triggered when the CCDC is enabled, unlike external sync mode where the
line counter runs even when the CCDC is stopped. We can't disable the
CCDC at VD1 time, as no VD0 interrupt would be generated for a short
frame, which would result in the CCDC being stopped and no VD interrupt
generated anymore. The CCDC is stopped from the VD0 interrupt handler
instead for BT.656.

Add initial support for OF based soc-camera devices that may be used
by any of the soc-camera drivers. The driver itself will need converting
to use OF.
These changes allow the soc-camera driver to do the connecting of any
async capable v4l2 device to the soc-camera driver. This has currently
been tested on the Renesas Lager board.
It currently only supports one input device per driver as this seems
to be the standard connection for these devices.

On some hardware (au0828/au8522), the hardware is broken with
regards to the initial pulse detection. So, the driver needs to
produce a fake start pulse. That limits the acceptable protocols,
as it is not possible to produce a fake pulse that would cover
all supported protocols.
So, allow the driver to explicitly set the allowed protocols.
If the driver doesn't specify, keep the old behavior.

Commits 21dc61d3c0 and 7a1dd50b89 reduced the board I2C
speed to 20 MHz by default, due to a I2C stretch issue:
while xc5000 uses i2c stretch when a command is sent to it,
au0828 doesn't support this feature.
However, this is needed only for Xceive tuners. The other
I2C devices can work at the max speed.
So, revert the workarounds at board level, handling it at
I2C level, only when talking with xc5000.

Commit 958c7c7e65 ("[media] v4l2-ctrls: fix corner case in round-to-range code") broke
controls that use a negative range.
The cause was a s32/u32 mixup: ctrl->step is unsigned while all others are signed. So
the result type of the expression '(ctrl)->maximum - ((ctrl)->step / 2)' became unsigned,
making 'val >= (ctrl)->maximum - ((ctrl)->step / 2)' true, since '((u32)-128) > 128'
(if val = -128, maximum = 128 and step = 1).
So carefully cast (step / 2) to s32.
There was one cast of step to s32 where it should have been u32 because both offset and
step are unsigned, so casting to signed makes no sense there. You do need a cast to u32
there, because otherwise architectures that have no 64-bit division start complaining
(step is a u64).

Some vendors have their on keymap table that are used on
all (or almost all) models for that vendor.
So, instead of specifying the keymap table per USB ID,
let's use the Vendor ID's table by default.
At the end, this will mean less code to be added when newer
devices for those vendors are added.
Of course, if rc_map is specified per board, it takes
precedence.
