Since this driver can be used for rk8xx series pmic, let's rename rk808 to rk8xx, to make it clear. Configs parts are done by sed -i "s/RK808/RK8XX/g" `grep RK808 -lr ./` Signed-off-by: Jacob Chen <jacob-chen@iotwrt.com>

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'

---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.

bool "Allow child devices for PMICs in SPL"

---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).
