| 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 rk8xx.c for direct functions | |
| for use in SPL). | |
