From 193b199a925b04e2d9bc9dde8bb63f6d55483b7d Mon Sep 17 00:00:00 2001 From: Icenowy Zheng Date: Mon, 9 Sep 2024 00:47:17 +0300 Subject: [PATCH] arm64: dts: sun50i-a64-pinephone: Add AF8133J to PinePhone New batches of PinePhones switched the magnetometer to AF8133J from LIS3MDL because lack of ST components. Both chips use the same PB1 pin, but in different modes. LIS3MDL uses it as an gpio input to handle interrupt. AF8133J uses it as an gpio output as a reset signal. It wasn't possible at runtime to enable both device tree nodes and detect supported sensor at probe time, because both drivers try to acquire the same gpio in different modes. Device tree fixup will be done in firmware without introducing new board revision and new dts.
