[PATCH v2 08/10] ARM: dts: sun9i: cubieboard4: Add AXP809 PMIC device node and regulators

From: Chen-Yu Tsai
Date: Mon Feb 15 2016 - 05:32:47 EST

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.
