From 84d678e330f80376456c764fe1f9c27d9b79610c Mon Sep 17 00:00:00 2001 From: Chen-Yu Tsai Date: Mon, 12 Jan 2015 12:34:09 +0800 Subject: [PATCH 6/7] ARM: dts: sun4i: cubieboard: add axp209 regulator nodes Origin: https://git.kernel.org/linus/ce124f7a18c5ebc9dc93aaec15aaef779c8708ae 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.
