From 5c04c4edf7218c16d34735f2e5916d6aab6d61ba Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Ond=C5=99ej=20Jirman?= Date: Tue, 26 Oct 2021 01:25:46 +0200 Subject: [PATCH 185/484] 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.
