From: Elaine Zhang <zhangqing@rock-chips.com>
Add support for the rk805 regulator. The regulator module consists
of 4 DCDCs, 3 LDOs.
The output voltages are configurable and are meant to supply power
to the main processor and other components.

The RK805 chip is a Power Management IC (PMIC) for multimedia and handheld
devices. It contains the following components:
- Regulators
- RTC
- Clocking
Both RK808 and RK805 chips are using a similar register map,
so we can reuse the RTC and Clocking functionality.

RK805 is one of Rockchip PMICs family, it has 2 output only GPIOs.
This driver is also designed for other Rockchip PMICs to expend.
Different PMIC maybe have different pin features, for example,
RK816 has one pin which can be used for TS or GPIO(input/out).
The mainly difference between PMICs pins are pinmux, direction
and output value, that is 'struct rk805_pin_config'.

+Pincontrol driver for RK805 Power management IC.
+
+RK805 has 2 pins which can be configured as GPIO output only.
+
+Please refer file <devicetree/bindings/pinctrl/pinctrl-bindings.txt>
+for details of the common pinctrl bindings used by client devices,
+including the meaning of the phrase "pin configuration node".
+
+Optional Pinmux properties:
+--------------------------
+Following properties are required if default setting of pins are required
+at boot.
+- pinctrl-names: A pinctrl state named per <pinctrl-binding.txt>.
+- pinctrl[0...n]: Properties to contain the phandle for pinctrl states per
+ <pinctrl-binding.txt>.
+
+The pin configurations are defined as child of the pinctrl states node. Each
+sub-node have following properties:
+
+Required properties:
+------------------
+- #gpio-cells: Should be two. The first cell is the pin number and the
+ second is the GPIO flags.
+
+- gpio-controller: Marks the device node as a GPIO controller.
+
+- pins: List of pins. Valid values of pins properties are: gpio0, gpio1.
+
+First 2 properties must be added in the RK805 PMIC node, documented in
+Documentation/devicetree/bindings/mfd/rk808.txt
+
+Optional properties:
+-------------------
+Following are optional properties defined as pinmux DT binding document
+<pinctrl-bindings.txt>. Absence of properties will leave the configuration
+on default.
+ function,
+ output-low,
+ output-high.
+
+Valid values for function properties are: gpio.
+
+Theres is also not customised properties for any GPIO.
+
+Example:
+--------
+rk805: rk805@18 {
+ compatible = "rockchip,rk805";
+ ...
+ gpio-controller;
+ #gpio-cells = <2>;
+
+ pinctrl-names = "default";
+ pinctrl-0 = <&pmic_int_l>, <&rk805_default>;
+
+ rk805_default: pinmux {
+ gpio01 {
+ pins = "gpio0", "gpio1";
+ function = "gpio";
+ output-high;
+ };
+ };
