Signed-off-by: Abhishek Pandit-Subedi --- Connector status has several unaligned bitfields (16-bit) that result in difficult to maintain macros. It may be better if we simply re-define these structs as u8[] and add bit range macros to access and cast these values. i.e. struct ucsi_connector_status { u8 raw_data[18]; ... \#define UCSI_CONSTAT_CONNECTOR_STATUS FIELD(u16, 15, 0) \#define UCSI_CONSTAT_BCD_PD_VER_OPER_MODE FIELD(u16, 85, 70) } GET_UCSI_FIELD(con->status, UCSI_CONSTAT_CONNECTOR_STATUS); SET_UCSI_FIELD(con->status, UCSI_CONSTAT_CONNECTOR_STATUS, 0); I didn't find a clear example of an existing mechanism to do this. Would love some pointers here if it already exists and some feedback from the maintainer if this is a direction you want to go.
