| 7 | For the multi-function PMIC devices, this can be used as parent I/O |
| 8 | device for each IC's interface. Then, each children uses its parent |

| 24 | Enable the driver for Sandbox PMIC emulation. The emulated PMIC device |
| 25 | depends on two drivers: |
| 26 | - sandbox PMIC I/O driver - implements dm pmic operations |
| 27 | - sandbox PMIC i2c emul driver - emulates the PMIC's I2C transmission |

| 31 | The Sandbox PMIC info: |
| 32 | * I/O interface: |
| 33 | - I2C chip address: 0x40 |
| 34 | - first register address: 0x0 |
| 35 | - register count: 0x10 |
| 36 | * Adjustable outputs: |
| 37 | - 2x LDO |
| 38 | - 2x BUCK |
| 39 | - Each, with a different operating conditions (header). |
| 40 | * Reset values: |
| 41 | - set by i2c emul driver's probe() (defaults in header) |
