| 2 | |
| 3 | This device uses two drivers: |
| 4 | - drivers/power/pmic/sandbox.c (for parent device) |
| 5 | - drivers/power/regulator/sandbox.c (for child regulators) |
| 6 | |
| 7 | This file describes the binding info for the PMIC driver. |
| 8 | |
| 9 | To bind the regulators, please read the regulator binding info: |
| 10 | - doc/device-tree-bindings/regulator/sandbox.txt |
| 11 | |
| 12 | Required PMIC node properties: |
| 13 | - compatible: "sandbox,pmic" |
| 14 | - reg = 0x40 |
| 15 | |
| 16 | Required PMIC's "emul" subnode, with property: |
| 17 | - compatible: "sandbox,i2c-pmic" |
| 18 | |
| 19 | With the above properties, the pmic device can be used for read/write only. |
| 20 | To bind each regulator, the optional regulator subnodes should exists. |
| 21 | |
| 22 | Optional subnodes: |
| 23 | - ldo/buck subnodes of each device's regulator (see regulator binding info) |
| 24 | |
| 25 | Example: |
| 26 | |
| 27 | sandbox_pmic { |
| 28 | compatible = "sandbox,pmic"; |
| 29 | reg = <0x40>; |
| 30 | |
| 31 | /* Mandatory for I/O */ |
| 32 | emul { |
| 33 | compatible = "sandbox,i2c-pmic"; |
| 34 | }; |
| 35 | }; |
