+except these properties:
- op_mode: describes the different operating modes of the LDO's with
power mode change in SOC. The different possible values are,
0 - always off mode
1 - on in normal mode
2 - low power mode
3 - suspend mode

The following are the names of the regulators that the s5m8767 pmic block
supports. Note: The 'n' in LDOn and BUCKn represents the LDO or BUCK number
