Some of the regulators on the MT6357 PMIC currently reference the fixed-regulator dt-binding, which enforces the presence of a regulator-fixed compatible. However since all regulators on the MT6357 PMIC are handled by a single mt6357-regulator driver, probed through MFD, the compatibles don't serve any purpose. In fact they cause failures in the DT kselftest since they aren't probed by the fixed regulator driver as would be expected. Furthermore this is the only dt-binding in this family like this: mt6359-regulator and mt6358-regulator don't require those compatibles. Commitd77e89b7b0("arm64: dts: mediatek: mt6357: Drop regulator-fixed compatibles") removed the compatibles from Devicetree, but missed updating the binding, which still requires them, introducing dt-binding errors. Remove the compatible requirement by referencing the plain regulator dt-binding instead to fix the dt-binding errors.

The MT6357 PMIC provides 5 BUCK and 29 LDO.
|
|
Regulators and nodes are named according to the regulator type:
|
|
- buck-<name>
|
|
- ldo-<name>.
|
|
MT6357 regulators node should be sub node of the MT6397 MFD node.
