Subject: [PATCH v10 0/4] MAX9286 GMSL Support (+RDACM20)

This series provides a pair of drivers for the GMSL cameras on the R-Car ADAS
platforms.

These drivers originate from Cogent Embedded, and have been refactored to split
the MAX9286 away from the RDACM20 drivers which were once very tightly coupled.

The MAX9286 is capable of capturing up to 4 streams simultaneously, and while
the V4L2-Multiplexed streams series is not available, this works purely on the
assumption that the receiver will correctly map each of the 4 VCs to separate
video nodes, as the RCar-VIN does.

This driver along with a camera driver for the RDACM20 and the
associated platform support for the Renesas R-Car Salvator-X, and the Eagle-V3M
can be found at:

  git://git.kernel.org/pub/scm/linux/kernel/git/kbingham/rcar.git gmsl/v10

This latest v10 cleans up the DT bindings validation, and several comments
from Sakari's review in v9.

It has been successfully tested to capture from all 4 inputs simultaneously.

We're very much hoping that we can aim to get the max9286 into the next
merge-window. Please let us know if there are any issues blocking this.
