-Regulators: All the regulators of RK8XX 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 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
-for more details
