[PATCH 7/9] ARM: dts: sun9i: a80-optimus: Add AXP806 PMIC device node and regulators

Chen-Yu Tsai wens at csie.org
Sat Aug 20 19:11:23 PDT 2016


The AXP806 PMIC is the secondary 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.
