[PATCH v13 0/6] Add Synopsys DesignWare HDMI RX Controller

[Tim Surber]

Hi Dmitry,

I did some more testing. That the Apple TV did not work was a bit 
misleading.

It was just, that the Apple TV defaulted to 4:4:4 Chroma which does not 
work at all for me. (The same happens using the vendor driver).

When I changed the EDID to match the vendor driver the HDMI handshake 
happened with 4:2:0 chroma, where I could verify even 4k60fps using your 
driver, nice!

So the remaining problems I see are:
- 4:4:4 chroma not working in any resolution
- 4:2:2 and RGB not working in 4k60fps (is this a hardware limitation?)

A possible workaround could be to disable these non supported formats in 
the default EDID.

Best regards,
TIm
