-Binding for Maxim MAX77802 regulators
-
-This is a part of device tree bindings of MAX77802 multi-function device.
-More information can be found in bindings/mfd/max77802.txt file.
-
-The MAX77802 PMIC has 10 high-efficiency Buck and 32 Low-dropout (LDO)
-regulators that can be controlled over I2C.
-
-Following properties should be present in main device node of the MFD chip.
-
-Optional properties:
-- inb1-supply: The input supply for BUCK1
-- inb2-supply: The input supply for BUCK2
-- inb3-supply: The input supply for BUCK3
-- inb4-supply: The input supply for BUCK4
-- inb5-supply: The input supply for BUCK5
-- inb6-supply: The input supply for BUCK6
-- inb7-supply: The input supply for BUCK7
-- inb8-supply: The input supply for BUCK8
-- inb9-supply: The input supply for BUCK9
-- inb10-supply: The input supply for BUCK10
-- inl1-supply: The input supply for LDO8 and LDO15
-- inl2-supply: The input supply for LDO17, LDO27, LDO30 and LDO35
-- inl3-supply: The input supply for LDO3, LDO5, LDO6 and LDO7
-- inl4-supply: The input supply for LDO10, LDO11, LDO13 and LDO14
-- inl5-supply: The input supply for LDO9 and LDO19
-- inl6-supply: The input supply for LDO4, LDO21, LDO24 and LDO33
-- inl7-supply: The input supply for LDO18, LDO20, LDO28 and LDO29
-- inl9-supply: The input supply for LDO12, LDO23, LDO25, LDO26, LDO32 and LDO34
-- inl10-supply: The input supply for LDO1 and LDO2
-
-Optional nodes:
-- regulators : The regulators of max77802 have to be instantiated
- under subnode named "regulators" using the following format.
-
- regulator-name {
- standard regulator constraints....
- };
- refer Documentation/devicetree/bindings/regulator/regulator.txt
-
-The regulator node name should be initialized with a string to get matched
-with their hardware counterparts as follow. The valid names are:
-
- -LDOn : for LDOs, where n can lie in ranges 1-15, 17-21, 23-30
- and 32-35.
- example: LDO1, LDO2, LDO35.
- -BUCKn : for BUCKs, where n can lie in range 1 to 10.
- example: BUCK1, BUCK5, BUCK10.
-
-The max77802 regulator supports two different operating modes: Normal and Low
-Power Mode. Some regulators support the modes to be changed at startup or by
-the consumers during normal operation while others only support to change the
-mode during system suspend. The standard regulator suspend states binding can
-be used to configure the regulator operating mode.
-
-The regulators that support the standard "regulator-initial-mode" property,
-changing their mode during normal operation are: LDOs 1, 3, 20 and 21.
-
-The possible values for "regulator-initial-mode" and "regulator-mode" are:
- 1: Normal regulator voltage output mode.
- 3: Low Power which reduces the quiescent current down to only 1uA
-
-The valid modes list is defined in the dt-bindings/regulator/maxim,max77802.h
-header and can be included by device tree source files.
-
-The standard "regulator-mode" property can only be used for regulators that
-support changing their mode to Low Power Mode during suspend. These regulators
-are: BUCKs 2-4 and LDOs 1-35. Also, it only takes effect if the regulator has
-been enabled for the given suspend state using "regulator-on-in-suspend" and
-has not been disabled for that state using "regulator-off-in-suspend".

+description: |
+ This is a part of device tree bindings for Maxim MAX77802 Power Management
+ Integrated Circuit (PMIC).
+
+ The Maxim MAX77686 provides 10 high-efficiency Buck and 32 Low-DropOut (LDO)
+ regulators.
+
+ See also Documentation/devicetree/bindings/mfd/maxim,max77802.yaml for
+ additional information and example.
+
+ Certain regulators support "regulator-initial-mode" and "regulator-mode".
+ The valid modes list is defined in the dt-bindings/regulator/maxim,max77802.h
+ and their meaning is:
+ 1 - Normal regulator voltage output mode.
+ 3 - Low Power which reduces the quiescent current down to only 1uA
+
+ The standard "regulator-mode" property can only be used for regulators that
+ support changing their mode to Low Power Mode during suspend. These
+ regulators are: bucks 2-4 and LDOs 1-35. Also, it only takes effect if the
+ regulator has been enabled for the given suspend state using
+ "regulator-on-in-suspend" and has not been disabled for that state using
+ "regulator-off-in-suspend".
