Subject: [PATCH v2 0/2] media: Add Amlogic Meson AO CEC Controller support

The Amlogic SoC embeds a standalone CEC controller, this patch adds a driver
for such controller.
The controller does not need HPD to be active, and could support up to max
5 logical addresses, but only 1 is handled since the Suspend firmware can
make use of this unique logical address to wake up the device.

The Suspend firmware configuration will be added in an other patchset.

Changes since v1 at [1] :
 - add timeout to wait busy, with error return
 - handle busy error in all read/write operations
 - add CEC_CAP_PASSTHROUGH
 - add bindings ack
