config DM_PMIC
bool "Enable Driver Model for PMIC drivers (UCLASS_PMIC)"
depends on DM
---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:
- 'drivers/power/pmic/pmic-uclass.c'
- 'include/power/pmic.h'
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).
