| ---help--- |
| This config enables the driver-model PMIC support. |
| UCLASS_PMIC - designed to provide an I/O interface for PMIC devices. |
| For the multi-function PMIC devices, this can be used as parent I/O |
| device for each IC's interface. Then, each children uses its parent |
| for read/write. For detailed description, please refer to the files: |

| config PMIC_CHILDREN |
| bool "Allow child devices for PMICs" |
| depends on DM_PMIC |
| default y |
| ---help--- |
| This allows PMICs to support child devices (such as regulators) in |
| SPL. This adds quite a bit of code so if you are not using this |
| feature you can turn it off. Most likely you should turn it on for |
| U-Boot proper. |
| |
| config SPL_PMIC_CHILDREN |
| bool "Allow child devices for PMICs in SPL" |
| depends on DM_PMIC |
| default y |
| ---help--- |
| This allows PMICs to support child devices (such as regulators) in |
| SPL. This adds quite a bit of code so if you are not using this |
| feature you can turn it off. In this case you may need a 'back door' |
| to call your regulator code (e.g. see rk808.c for direct functions |
| for use in SPL). |
