Subject: [PATCH 107/391] arm64: dts: sun50i-a64-pinephone: Workaround broken
|
|
HDMI HPD signal
|
|
|
|
HDMI HPD signal from ANX7688 to SoC's HDMI PHY is wrongly level
|
|
shifted and does not register most of the time at the SoC's input.
|
|
|
|
We need to do the signalling in software. Link anx7688 to hdmi
|
|
driver via extcon interface.
