1config 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'
11	- 'include/power/pmic.h'

13config PMIC_CHILDREN
14	bool "Allow child devices for PMICs"
15	depends on DM_PMIC
16	default y
17	---help---
18	This allows PMICs to support child devices (such as regulators) in
19	SPL. This adds quite a bit of code so if you are not using this
20	feature you can turn it off. Most likely you should turn it on for
21	U-Boot proper.
22
23config SPL_PMIC_CHILDREN
24	bool "Allow child devices for PMICs in SPL"
25	depends on DM_PMIC
26	default y
27	---help---
28	This allows PMICs to support child devices (such as regulators) in
29	SPL. This adds quite a bit of code so if you are not using this
30	feature you can turn it off. In this case you may need a 'back door'
31	to call your regulator code (e.g. see rk8xx.c for direct functions
32	for use in SPL).
