Subject: [PATCH] dt-bindings: regulator: sprd,sc2731-regulator: convert to
YAML
Convert the Spreadtrum SC2731 regulator bindings to DT schema.
Change during conversion:
- switch compatible from sprd,sc27xx-regulator to sprd,sc2731-regulator,
same as the only in-tree user has done back in 2019 [1]
[1] https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/arch/arm64/boot/dts/sprd/sc2731.dtsi?h=v6.9&id=0419a75b1808dda225b17ba1509f195f23c0db88

-Spreadtrum SC2731 Voltage regulators
-
-The SC2731 integrates low-voltage and low quiescent current DCDC/LDO.
-14 LDO and 3 DCDCs are designed for external use. All DCDCs/LDOs have
-their own bypass (power-down) control signals. External tantalum or MLCC
-ceramic capacitors are recommended to use with these LDOs.
-
-Required properties:
- - compatible: should be "sprd,sc27xx-regulator".
-
-List of regulators provided by this controller. It is named according to
-its regulator type, BUCK_<name> and LDO_<name>. The definition for each
-of these nodes is defined using the standard binding for regulators at
-Documentation/devicetree/bindings/regulator/regulator.txt.
-
-The valid names for regulators are:
-BUCK:
- BUCK_CPU0, BUCK_CPU1, BUCK_RF
-LDO:
- LDO_CAMA0, LDO_CAMA1, LDO_CAMMOT, LDO_VLDO, LDO_EMMCCORE, LDO_SDCORE,
- LDO_SDIO, LDO_WIFIPA, LDO_USB33, LDO_CAMD0, LDO_CAMD1, LDO_CON,
- LDO_CAMIO, LDO_SRAM
-
-Example:
- regulators {

-
- vddarm0: BUCK_CPU0 {
- regulator-name = "vddarm0";
- regulator-min-microvolt = <400000>;
