Subject: [PATCH 4/7] ARM: dts: sun7i: cubieboard2: add axp209 regulator nodes
|
|
Origin: https://git.kernel.org/linus/ae265c801ffdbd58e4c7a83efc8dc08932de1f74
|
|
|
|
This patch adds the regulator nodes for the axp209 by including
|
|
the axp209 dtsi. As the inputs of these regulators are from the
|
|
axp209's PS output, which is basically just a mux over the 2
|
|
inputs, it is considered to be unregulated. Thus we do not provide
|
|
input supply properties for them.
|
|
|
|
The regulator names and constraints are based on the board
|
|
schematics and the SoC datasheet.
|
|
|
|
DCDC2 is used as the cpu power supply. This patch also references
|
|
it from the cpu node.
|
|
|
|
Also get rid of axp209 properties already set in axp209.dtsi.
