This is a generic implementation. Add CONFIG_SYSRESET_CMD_POWEROFF to signal when we need it. Enable it from the STPMIC1 config and in sandbox. The config flag is transitionary, that is it can be removed after all poweroff implementations use sysreset, and just have CMD_POWEROFF depend on sysreset.

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

feature you can turn it off. Most likely you should turn it on for

U-Boot proper.
