Subject: [PATCH v5 1/5] dt-bindings: Add RK808 device tree bindings document
Add device tree bindings documentation and a header file
for rockchip's RK808 pmic.
Signed-off-by: Chris Zhong <zyw@...k-chips.com>
---
Changes in v5:
Adviced by doug
- add some error checking in probe
- move "rockchip,rk808.h" into the patch about dt-bindings
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

+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. Not all regulators for the given
+ device need to be present. The definition for each of these nodes is defined
+ using the standard binding for regulators found at
+ Documentation/devicetree/bindings/regulator/regulator.txt.
+- #clock-cells: the value should be 1
+- The following are the names of the regulators that the rk808 pmic block
+ supports. Note: The 'n' below represents the number as per the datasheet:
+
+ - DCDC_REGn
+ - valid values for n are 1 to 4.
+ - LDO_REGn
+ - valid values for n are 1 to 8.
+ - SWITCH_REGn
+ - valid values for n are 1 to 2.
+
+Optional properties:
+- clock-output-names : From common clock binding to override the
+ default output clock name
+- rockchip,system-power-controller: Telling whether or not this pmic is controlling
+ the system power.
+
+Example:

+ compatible = "rockchip,rk808";
