UCLASS_REGULATOR - designed to provide a common API for basic regulator's
|
|
functions, like get/set Voltage or Current value, enable state, etc...
|
|
Note:
|
|
When enabling this, please read the description, found in the files:
|
|
- 'include/power/pmic.h'
|
|
- 'include/power/regulator.h'
|
|
- 'drivers/power/pmic/pmic-uclass.c'
|
|
- 'drivers/power/pmic/regulator-uclass.c'
|
|
It's important to call the device_bind() with the proper node offset,
|
|
when binding the regulator devices. The pmic_bind_childs() can be used
|
|
for this purpose if PMIC I/O driver is implemented or dm_scan_fdt_dev()
|
|
otherwise. Detailed information can be found in the header file.
