[PATCH 0/5] Add tda998x (HDMI) support to atmel-hlcdc

[Peter Rosin]

Hi!

I naively thought that since there was support for both nxp,tda19988 (in
the tda998x driver) and the atmel-hlcdc, things would be a smooth ride.
But it wasn't, so I started looking around, and found some missing
pieces in the tilcdc driver. A "stole" some things and made it work
for my use case.

During this, I found that the tda998x driver never sets the format in
the connector display_info. Thus, the atmel-hlcdc driver fails to select
output format. Since I had similar problems with ds90c185 lvds encoder
I added patches to override the atmel-hlcdc output format via a DT
property and things start to play together.

Since this series superseeds the bridge series, I have included the
leftover bindings patch for the ti,ds90c185 here. I also noticed that
the driver date for atmel-hlcdc is bonkers, and added a patch for that.

However, I don't know if the tilcdc driver is interfacing with the
tda998x driver in a sane and modern way, and I don't know if I have
missed any subtle point when I "stole" the code and componentized the
atmel-hlcdc driver. I also have not tested how this behaves if I run
with the components as modules (not targeting that).

Anyway, this series solves some real issues for my HW.

Cheers,
Peter
