From 6eeb4180d4b9887b6bc8bbe0a22c1ce3634417f0 Mon Sep 17 00:00:00 2001 From: Chen-Yu Tsai Date: Wed, 26 Sep 2018 21:23:39 +0800 Subject: [PATCH] ARM: dts: sunxi: h3-h5: Add Bananapi M2+ v1.2 device trees Bananapi released an updated revision of the H3/H5 based Bananapi M2+. Version 1.2 enables voltage control for the CPU's regulator by using a GPIO line to toggle a MOSFET that can change the effective resistance value in the regulator's feedback network. This patch adds a common .dtsi file for this new revision, which includes the original common sunxi-bananapi-m2-plus.dtsi file, and adds the GPIO-controlled regulator and a cpu-supply reference. H3 and H5 variant dts files are added as well.
