Hi Angelo, thanks for this. I will do a proper review in the coming days of this series anyway, but upfront for future V2: - you should provide some sort of documentation for this new vendor protocol and its messages, as an example from IMX: drivers/firmware/arm_scmi/vendors/imx/imx95.rst - where is the SCMI driver that will call all the new vendor ops defined in: scmi_mtk_protocol.h ? Thanks, Cristian
