| 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 |
| |

| 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 |
