[PATCH v2 0/4] media: allegro: move driver out of staging

[Michael Tretter <m.tretter@pengutronix.de>]

Hello,

With the V4L2 stateful encoder spec being finished, the Allegro encoder driver
is ready to be moved from staging to mainline.

While not directly related, I used the opportunity to convert the dt-binding
to YAML, to remove the custom draining state handling from the driver and to
rename a badly named field in the MCU messages.

v2 fixes the reported warnings in the YAML dt-bindings.

There are no functional changes in the actual driver since v1, but I am
sending the updated v4l2-compliance result anyway.

Michael
