RK817 Power Management Integrated Circuit
Required properties:
- compatible: "rockchip,rk817"
- reg: I2C slave address
- interrupt-parent: The parent interrupt controller.
- interrupts: the interrupt outputs of the controller.
- #clock-cells: from common clock binding; shall be set to 1 (multiple clock
outputs). See <dt-bindings/clock/rockchip,rk808.h> for clock IDs.
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.
- vcc1-supply: The input supply for DCDC_REG1
- vcc2-supply: The input supply for DCDC_REG2
- vcc3-supply: The input supply for DCDC_REG3
- vcc4-supply: The input supply for DCDC_REG4
- vcc5-supply: The input supply for LDO_REG1, LDO_REG2, LDO_REG3
- vcc6-supply: The input supply for LDO_REG4, LDO_REG5, LDO_REG6
- vcc7-supply: The input supply for LDO_REG7, LDO_REG8, LDO_REG9
- vcc8-supply: The input supply for BOOST
- vcc9-supply: The input supply for OTG_SWITCH
Regulators: All the regulators of RK817 to be instantiated shall be
listed in a child node named 'regulators'. Each regulator is represented
by a child node of the 'regulators' node.
regulator-name {
/* standard regulator bindings here */
};
Following regulators of the RK817 PMIC block are supported. Note that
the 'n' in regulator name, as in DCDC_REGn or LDOn, represents the DCDC or LDO
number as described in RK808 datasheet.
- DCDC_REGn
- valid values for n are 1 to 4.
- LDO_REGn
- valid values for n are 1 to 9.
There are three pins needed config, named "gpio_ts" "gpio_gt" "gpio_slp".
The gpio_gt and gpio_ts pins support the gpio function.
For using a gpio function, dtsi need the following info:
pinctrl-names = "default";
pinctrl-0 = <&rk817_ts_gpio1>, <&rk817_gt_gpio2>;
gpios = <&pinctrl_rk8xx 1 GPIO_ACTIVE_HIGH>,
<&pinctrl_rk8xx 2 GPIO_ACTIVE_HIGH>;
The gpio_slp pin is for controlling the pmic states, as below:
reset
power down
sleep
Standard regulator bindings are used inside regulator subnodes. Check
Documentation/devicetree/bindings/regulator/regulator.txt
for more details
