Regulators: All the regulators of RK8XX to be instantiated shall be
listed in a child node named 'regulators'. Each regulator is represented

regulator-name {
/* standard regulator bindings here */
};
Following regulators of the RK805 PMIC regulators are supported. Note that
the 'n' in regulator name, as in DCDC_REGn or LDOn, represents the DCDC or LDO
number as described in RK805 datasheet.
- DCDC_REGn
- valid values for n are 1 to 4.
- LDO_REGn
- valid values for n are 1 to 3
Following regulators of the RK808 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 8.
- SWITCH_REGn
- valid values for n are 1 to 2
Following regulators of the RK809 and RK817 PMIC blocks are supported. Note that
the 'n' in regulator name, as in DCDC_REGn or LDOn, represents the DCDC or LDO
number as described in RK809 and RK817 datasheets.

It is necessary to configure three pins for both the RK809 and RK817, the three
pins are "gpio_ts" "gpio_gt" "gpio_slp".
The gpio_gt and gpio_ts pins support the gpio function.
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
