This series includes feature rework, feature additions and bug fixes for the
atmel-isc driver.
It applies only on top of my previous patchset:
media: atmel: atmel-isc: removed ARGB32 added ABGR32 and XBGR32
media: atmel: atmel-isc: reworked driver and formats
available at:
https://git.linuxtv.org/hverkuil/media_tree.git/commit/?h=for-v5.2b&id=03ef1b56cba6ad17f6ead13c85a81e0e80fbc9d1

One open question is regarding the WHITE_BALANCE error returns: it would seem
logical to return EAGAIN or EBUSY, but this is not compliant with
v4l2-compliance.
Does it make sense to return success on every occasion? even if the
DO_WHITE_BALANCE does nothing?
In this series I used the return EAGAIN or EBUSY from the v4l2-ctrls, but I
can change if always success is a better way of returning (even if normally
a return value serves this exact purpose - return some code )
