1 | config DM_PMIC |
2 | bool "Enable Driver Model for PMIC drivers (UCLASS_PMIC)" | |
3 | depends on DM | |
4 | ---help--- | |
5 | This config enables the driver-model PMIC support. | |
6 | UCLASS_PMIC - designed to provide an I/O interface for PMIC devices. | |
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 | |
9 | for read/write. For detailed description, please refer to the files: | |
10 | - 'drivers/power/pmic/pmic-uclass.c' | |

16 | ---help--- | |
17 | This config enables implementation of driver-model pmic uclass features | |
f415a3ec | 18 | for PMIC MAX77686. The driver implements read/write operations. |

21 | bool "Enable Driver Model for emulated Sandbox PMIC " | |
22 | depends on DM_PMIC | |
23 | ---help--- | |
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) | |
