Quite a lot of work going on the core this release, mainly around system
initialization, but a quiet release for drivers:
- Fixes for registration of multiple regulators on a PMIC from Javier
Martinez Canillas and Jon Hunter.
- Cleanups to the regulator_get() code from Dmitry Torokhov
- Lots of constifcation of structs from Bhumika Goyal
- Support for Motorola CPCAP regulators from Tony Lindgren.

Motorola CPCAP PMIC voltage regulators |
||||
------------------------------------ |
||||
|
||||
Requires node properties: |
||||
- "compatible" value one of: |
||||
"motorola,cpcap-regulator" |
||||
"motorola,mapphone-cpcap-regulator" |
||||
|
||||
Required regulator properties: |
||||
- "regulator-name" |
||||
- "regulator-enable-ramp-delay" |
||||
- "regulator-min-microvolt" |
||||
- "regulator-max-microvolt" |
||||
|
||||
Optional regulator properties: |
||||
- "regulator-boot-on" |
||||
|
||||
See Documentation/devicetree/bindings/regulator/regulator.txt |
||||
for more details about the regulator properties. |
||||
|
||||
Example: |
||||
|
||||
cpcap_regulator: regulator { |
||||
compatible = "motorola,cpcap-regulator"; |
||||
|
||||
cpcap_regulators: regulators { |
||||
sw5: SW5 { |
||||
regulator-min-microvolt = <5050000>; |
||||
regulator-max-microvolt = <5050000>; |
||||
regulator-enable-ramp-delay = <50000>; |
||||
regulator-boot-on; |
