Add PCA9450 regulator driver. This is complementary driver for the BUCKn and LDOn regulators provided by the PCA9450 PMIC driver. Currently the driver permits reading the settngs and configuring the BUCKn and LDOn regulators.

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'

|
|
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.
