| 2 | |
| 3 | This device uses two drivers: |
| 4 | - drivers/power/pmic/max77686.c (as parent I/O device) |
| 5 | - drivers/power/regulator/max77686.c (for child regulators) |
| 6 | |
| 7 | This file describes the binding info for the REGULATOR driver. |
| 8 | |
| 9 | First, please read the binding info for the pmic: |
| 10 | - doc/device-tree-bindings/pmic/max77686.txt |
| 11 | |
| 12 | Required subnode: |
| 13 | - voltage-regulators: required for the PMIC driver |
| 14 | |
| 15 | Required properties: |
| 16 | - regulator-name: used for regulator uclass platform data '.name' |
| 17 | |
| 18 | Optional: |
| 19 | - regulator-min-microvolt: minimum allowed Voltage to set |
| 20 | - regulator-max-microvolt: minimum allowed Voltage to set |
| 21 | - regulator-always-on: regulator should be never disabled |
| 22 | - regulator-boot-on: regulator should be enabled by the bootloader |
| 23 | |
| 24 | Example: |
