regulator: dt-bindings: mt6357: Drop fixed compatible requirement

2025-06-19T13:41:07Z

commit 9cfdd7752ba5f8cc9b8191e8c9aeeec246241fa4 upstream. 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. Commit d77e89b7b03f ("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.

Add the compatible string "nxp,pf9453" for the PF9453 regulator. The PF9453 is similar to the PCA9460 but supports only LDO1, LDO2, LDO_SVNS, and BUCK[1-4]. Restrict LDO and BUCK numbers for nxp,pf9453 and keep the same restriction for other compatible strings.
