From 40df91a894e9298d0f052acb6960f12ace5bee24 Mon Sep 17 00:00:00 2001 From: Tobias Schramm Date: Tue, 14 Apr 2020 18:39:51 +0200 Subject: [PATCH] arm64: dts: rockchip: fix inverted headphone detection on Pinebook Pro On the Pinebook Pro the headphone jack is dual use. It can be used either as a normal headphone jack or as a debug serial connection. This functionality is controlled via a small hardware switch on the mainboard. Unfortunately flipping this switch biases the headphone detection switch inside the headphone jack at 3.3 V if in `debug UART` position but to GND when in `headphone out` position. This results in an inversion of the headphone detection logic depending on the switch position. Since the headphone jack can only be used for audio when in `headphone out` position this commit changes the headphone detect GPIO logic to be correct for that case rather than for the debug UART.
