From e53568caa25c530a0fc4e3c2e1c275119fba7f91 Mon Sep 17 00:00:00 2001 From: Ondrej Jirman Date: Fri, 3 Jul 2020 21:48:41 +0200 Subject: [PATCH] arm64: dts: allwinner: Add support for PinePhone revision 1.2 Revision 1.2 should be the final production version of the PinePhone. It has most of the known HW quirks fixed. Interrupt to the magnetometer is routed correctly, in this revision. The bulk of the changes are in how modem and the USB-C HDMI bridge chip is powered and where the signals from the modem are connected. Also backlight intensity seemingly behaves differently, than on the 1.1 and 1.0 boards, and the PWM duty cycle where backlight starts to work is 10% (as tested on 2 1.2 PinePhones I have access to).
