Subject: [PATCH 0/2] drm: bridge: adv7511: CEC support for ADV7535

From: Alvin Šipraga <alsi@...g-olufsen.dk>

We have an ADV7535 which is nominally supported by this driver. These
two patches fix up the driver to get CEC working too.

The first adds the basic support by correcting some register offsets.

The second addresses an issue we saw with CEC RX on the ADV7535. It
hasn't been tested with the other chips (e.g. ADV7533), although it
should be compatible. I'm sending it against drm-misc-next because the
issue wasn't reported for other chips, and ADV7535 didn't have CEC
support before. But feel free to take it into -fixes instead.

Alvin Šipraga (2):
  drm: bridge: adv7511: enable CEC support for ADV7535
  drm: bridge: adv7511: use non-legacy mode for CEC RX
