| Sandbox, PMIC regulators |
| |
| This device uses two drivers: |
| - drivers/power/pmic/sandbox.c (as parent I/O device) |
| - drivers/power/regulator/sandbox.c (for child regulators) |
| |
| This file describes the binding info for the REGULATOR driver. |
| |
| First, please read the binding info for the PMIC: |
| - doc/device-tree-bindings/pmic/sandbox.txt |
| |
| Required subnodes: |
| - ldoN { }; |
| - buckN { }; |
| |
| The sandbox PMIC can support: ldo1, ldo2, buck1, buck2. |
| |
| For each PMIC's regulator subnode, there is one required property: |
| - regulator-name: used for regulator uclass platform data '.name' |
| |
| Optional: |
| - regulator-min-microvolt: minimum allowed Voltage to set |
| - regulator-max-microvolt: minimum allowed Voltage to set |
| - regulator-min-microamps: minimum allowed Current limit to set (LDO1/BUCK1) |
| - regulator-max-microamps: minimum allowed Current limit to set (LDO1/BUCK1) |
| - regulator-always-on: regulator should be never disabled |
| - regulator-boot-on: regulator should be enabled by the bootloader |
| |
| Example PMIC's regulator subnodes: |
| |
| ldo1 { |
| regulator-name = "VDD_1.0V"; |
| regulator-min-microvolt = <1000000>; |
| regulator-max-microvolt = <1200000>; |
| regulator-min-microamps = <100000>; |
| regulator-max-microamps = <400000>; |
| regulator-always-on; |
| }; |
| |
| buck2 { |
| regulator-name = "VDD_1.8V"; |
| regulator-min-microvolt = <1800000>; |
| regulator-max-microvolt = <1800000>; |
| regulator-boot-on; |
| }; |
