[PATCH 0/2] drm/sun4i: dw-hdmi: Improve CEC support

[Jernej Skrabec]

It turns out that additional logic between HDMI CEC controller and
pins on PHY on some Allwinner SoCs prevents proper communication.
It might be possible to fix it, but it's much easier and less error
prone to just directly drive pins using software implementation of
CEC protocol.

Let me know what do you think.

Best regards,
Jernej
