The AXP209 PMIC is used with some Allwinner SoCs. This patch adds a dtsi file listing all the regulator nodes. The regulators are initialized based on their device node names. Signed-off-by: Chen-Yu Tsai <wens@csie.org> --- changes since v1: - Moved interrupt controller properties to this patch - Added default names for all the regulators - Removed needless comment above regulators section --- arch/arm/boot/dts/axp209.dtsi | 97 +++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 97 insertions(+) create mode 100644 arch/arm/boot/dts/axp209.dtsi
