- The regulator-compatible property of regulator should initialized with string
-to get matched with their hardware counterparts as follow:
-
- -LDOn : for LDOs, where n can lie in range 1 to 26.
- example: LDO1, LDO2, LDO26.
- -BUCKn : for BUCKs, where n can lie in range 1 to 9.
- example: BUCK1, BUCK5, BUCK9.
-
- Regulators which can be turned off during system suspend:
- -LDOn : 2, 6-8, 10-12, 14-16,
- -BUCKn : 1-4.
- Use standard regulator bindings for it ('regulator-off-in-suspend').
-
- LDO20, LDO21, LDO22, BUCK8 and BUCK9 can be configured to GPIO enable
- control. To turn this feature on this property must be added to the regulator
- sub-node:
- - maxim,ena-gpios : one GPIO specifier enable control (the gpio
- flags are actually ignored and always
- ACTIVE_HIGH is used)
