rk808.txt: Add device tree bindings for rockchip's rk808 pmic. Signed-off-by: Chris Zhong <zyw@xxxxxxxxxxxxxx> --- Changes in v4: Adviced by doug - add "clock-output-names" propertiey - add a header file "rockchip,rk808.h" Changes in v3: - fix compile err Changes in v2: Adviced by javier.martinez - separated from rtc-rk808.c Documentation/devicetree/bindings/mfd/rk808.txt | 133 +++++++++++++++++++++++ 1 file changed, 133 insertions(+) create mode 100644 Documentation/devicetree/bindings/mfd/rk808.txt diff --git a/Documentation/devicetree/bindings/mfd/rk808.txt b/Documentation/devicetree/bindings/mfd/rk808.txt new file mode 100644 index 0000000..a9368fc --- /dev/null +++ b/Documentation/devicetree/bindings/mfd/rk808.txt @@ -0,0 +1,133 @@ +RK808 Power Management Integrated Circuit + +Required properties: +- compatible: "rockchip,rk808" +- reg: I2C slave address +- interrupt-parent: The parent interrupt controller. +- interrupts: the interrupt outputs of the controller. +- pinctrl-names: Should contain only one value - "default". +- pinctrl-0: Should specify pin control groups used for this controller. +- regulators: This is the list of child nodes that specify the regulator + initialization data for defined regulators.
