ARM SCMI v3.2 Table 24 Pin Configuration Type and Enumerations: '192 -255 OEM specific units'. i.MX95 System Manager FW supports SCMI PINCTRL protocol, but uses OEM Pin Configuration type, so extend the driver to support custom params. The node will be as below: pinctrl_usdhc1: usdhc1-pins { sd1cmd { ==> this is needed, so there is a patterProperties in nxp,imx95-scmi-pinctrl.yaml pins = "sd1cmd"; nxp,func-id = <0>; nxp,pin-conf = <0x138e>; }; sd1data { pins = "sd1data"; nxp,func-id = <0>; nxp,pin-conf = <0x138e>; }; }; This patchset depends on [1].
