Subject[PATCH v2 5/5] media: atmel-isc: Rework the format list
Date
To improve the readability of code, split the format array into two,
one for the format description, other for the register configuration.
Meanwhile, add the flag member to indicate the format can be achieved
from the sensor or be produced by the controller, and rename members
related to the register configuration.

Also add more formats support: GREY, ARGB444, ARGB555 and ARGB32.

Signed-off-by: Wenyou Yang <wenyou.yang@microchip.com>

Changes in v2:
- Add the new patch to remove the unnecessary member from
isc_subdev_entity struct.
- Rebase on the patch set,
[PATCH 0/6] [media] Atmel: Adjustments for seven function implementations
