[PATCH 08/11] ARM: dts: sun9i: a80-optimus: Add AXP809 PMIC device node and regulators

From: Chen-Yu Tsai <hidden>
Date: 2016-02-02 10:29:22
Also in: linux-arm-kernel, lkml
Subsystem: the rest · Maintainer: Linus Torvalds

The AXP809 PMIC is the primary PMIC. It provides various supply voltages
for the SoC and other peripherals. The PMIC's interrupt line is
connected to NMI pin of the SoC.
