Commit e93e7fd9f5a3fffec7792dbcc4c3574653effda7 ("v4l2: uvcvideo: Allow
using larger buffers") reworked the buffer size sanity check at buffer
completion time to use the frame size instead of the allocated buffer
size. However, it introduced two bugs in doing so:
- it assigned the allocated buffer size to the frame_size field, instead
of assigning the correct frame size
- it performed the assignment in the S_FMT handler, resulting in the
frame_size field being uninitialized if the userspace application
doesn't call S_FMT.
Fix both issues by removing the frame_size field and validating the
buffer size against the UVC video control dwMaxFrameSize.

The random_line buffer must be twice the maximum width, but it only allocated
the maximum width, so it was only half the size it needed to be.
Surprisingly I never saw the kernel fail on this, but the same TPG code used in
qv4l2 crashed and valgrind helped me track this bug down.

The cpufreq-dt driver tries to get a regulator for each CPU. This
regulator is optional, but when not present, a scary message "failed
to get cpuX regulator" is displayed. To solve this, we reduce the
severity of the message from dev_warn() to dev_dbg() and we reword the
message to not be as scary.

This commit extends the cpufreq-dt driver to take a platform_data

share the same clock or whether each CPU has a separate clock.

This commit extends the cpufreq_driver structure with an additional
'void *driver_data' field that can be filled by the ->probe() function
of a cpufreq driver to pass additional custom information to the
driver itself.
A new function called cpufreq_get_driver_data() is added to allow a
cpufreq driver to retrieve those driver data, since they are typically
needed from a cpufreq_policy->init() callback, which does not have
access to the cpufreq_driver structure. This function call is similar
to the existing cpufreq_get_current_driver() function call.

This patch adds support for the watchdog hardware found in A31 and
newer SoCs. This new hardware has registers at different offsets, and
the system reset control has been split out of the "mode" register
into a new "configuration" register.

lines for each watchdog, instead of sharing an interrupt line and
registers with the timer block.
