The SCMI clock IDs are part of firmware ABI, for sure. Does that imply they are part of DT ABI too ? Or, is there by any chance a plan to allow e.g. resolution of SCMI clock IDs by their shortnames, and allow SCMI clock IDs to change across different firmware versions, even on the same platform ? -- Best regards, Marek Vasut
