From 1fc61ed04d309b0b8b3562acf701ab988eee12de Mon Sep 17 00:00:00 2001 From: Markus Reichl Date: Mon, 6 Jan 2020 22:16:28 +0100 Subject: [PATCH] arm64: dts: rockchip: Enable mp8859 regulator on rk3399-roc-pc The rk3399-roc-pc uses a MP8859 DC/DC converter for 12V supply. This supplies 5V only in default state after booting. Now we can control the output voltage via I2C interface. Add a node for the driver to reach 12V.
