Subject: [PATCH v2 06/17] dt_bindings: regulator: Add ROHM BD71815 PMIC regulators
Date: Tue, 19 Jan 2021 09:17:09 +0200 [thread overview]
Message-ID: <950a87e680822ab6457ff95bba96730fed93e14d.1611037866.git.matti.vaittinen@fi.rohmeurope.com> (raw)
In-Reply-To: <cover.1611037866.git.matti.vaittinen@fi.rohmeurope.com>
Add binding documentation for regulators on ROHM BD71815 PMIC.
5 bucks, 7 LDOs and a boost for LED.
Signed-off-by: Matti Vaittinen <matti.vaittinen@fi.rohmeurope.com>

Changes since v1:
- Changed patch order to fix ref dependecy
- Added missing schema for nodes wled, ldodvref, ldolpsr

+description: |
+ This module is part of the ROHM BD718215 MFD device. For more details
+ see Documentation/devicetree/bindings/mfd/rohm,bd71815-pmic.yaml.
+
+ The regulator controller is represented as a sub-node of the PMIC node
+ on the device tree.
+
+ The valid names for BD71815 regulator nodes are
+ buck1, buck2, buck3, buck4, buck5,
+ ldo1, ldo2, ldo3, ldo4, ldo5,
+ ldodvref, ldolpsr, wled

+ rohm,dvs-run-voltage:

+ comments below for bucks/LDOs which support this. 0 means
+ regulator should be disabled at RUN state.

+ minimum: 0

+
+ rohm,dvs-snvs-voltage:
+ description:
+ Whether to keep regulator enabled at "SNVS" state or not.
+ 0 means regulator should be disabled at SNVS state, non zero voltage
+ keeps regulator enabled. BD71815 does not change voltage level
+ when PMIC transitions to SNVS.SNVS voltage depends on the previous
+ state (from which the PMIC transitioned to SNVS).
+ $ref: "/schemas/types.yaml#/definitions/uint32"
+ minimum: 0
+ maximum: 3300000
+
+ rohm,dvs-suspend-voltage:
+ description:
+ PMIC "SUSPEND" state voltage in uV when PMIC HW states are used. See
+ comments below for bucks/LDOs which support this. 0 means
+ regulator should be disabled at SUSPEND state.
+ $ref: "/schemas/types.yaml#/definitions/uint32"
+ minimum: 0
+ maximum: 3300000
+
+ rohm,dvs-lpsr-voltage:
+ description:
+ PMIC "LPSR" state voltage in uV when PMIC HW states are used. See
+ comments below for bucks/LDOs which support this. 0 means
+ regulator should be disabled at LPSR state.
+ $ref: "/schemas/types.yaml#/definitions/uint32"
+ minimum: 0
+ maximum: 3300000
+
+ # Bucks 1 and 2 support giving separate voltages for operational states
+ # (RUN /CLEAN according to data-sheet) and non operational states
+ # (LPSR/SUSPEND). The voltage is automatically changed when HW
+ # state changes. Omitting these properties from bucks 1 and 2 leave
+ # buck voltages to not be toggled by HW state. Enable status may still
+ # be toggled by state changes depending on HW default settings.
+ #
+ # Bucks 3-5 and ldos 1-5 support setting the RUN state voltage here.
+ # Given RUN voltage is used at all states if regulator is enabled at
+ # given state.
+ # Values given for other states are regarded as enable/disable at
+ # given state (see below).
+ #
+ # All regulators except WLED support specifying enable/disable status
+ # for each of the HW states (RUN/SNVS/SUSPEND/LPSR). HW defaults can
+ # be overridden by setting voltage to 0 (regulator disabled at given
+ # state) or non-zero (regulator enabled at given state). Please note
+ # that setting non zero voltages for bucks 1/2 will also enable voltage
+ # changes according to state change.
