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:

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.

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'

for use in SPL).
