Subject: [PATCH v4] dt-bindings: mfd: Convert stpmic1 bindings to json-schema
Convert stpmic1 bindings to json-schema.
Signed-off-by: Benjamin Gaignard <benjamin.gaignard@...com>
---
version 4:
- move on uppder node $ref: ../regulator/regulator.yaml
- move fixed strings under properties field
- remove unneeded () in patternProperties
- keep ldo3 separate from other ldo properties
Note:
- 'st,mask-reset' property stay in each subnode, I don't find
the syntax to avoid dupliquate it.
- ldo6-supply and all possible *-supply are describe by this regular
expression: ^(buck[1-4]|ldo[1-6]|boost|pwr_sw[1-2])-supply$":
version 3:
- put $ref under allOf keyword
- for each regulator node add the list of supported regulator properties

-STMicroelectronics STPMIC1 Voltage regulators
-
-Regulator Nodes are optional depending on needs.
-
-Available Regulators in STPMIC1 device are:
- - buck1 for Buck BUCK1
- - buck2 for Buck BUCK2
- - buck3 for Buck BUCK3
- - buck4 for Buck BUCK4
- - ldo1 for LDO LDO1
- - ldo2 for LDO LDO2
- - ldo3 for LDO LDO3
- - ldo4 for LDO LDO4
- - ldo5 for LDO LDO5
- - ldo6 for LDO LDO6
- - vref_ddr for LDO Vref DDR
- - boost for Buck BOOST
- - pwr_sw1 for VBUS_OTG switch
- - pwr_sw2 for SW_OUT switch
-
-Switches are fixed voltage regulators with only enable/disable capability.
-
-Optional properties:
-- st,mask-reset: mask reset for this regulator: the regulator configuration
- is maintained during pmic reset.
-- regulator-over-current-protection:
- if set, all regulators are switched off in case of over-current detection
- on this regulator,
- if not set, the driver only sends an over-current event.
-- interrupts: index of current limit detection interrupt
-- <regulator>-supply: phandle to the parent supply/regulator node
- each regulator supply can be described except vref_ddr.
-- regulator-active-discharge: can be used on pwr_sw1 and pwr_sw2.
