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
