are the calls to set_remote_state required? 0 is not the IRIS/VENUS remote processor. If it is legacy, maybe they can be phased out?
FWIW, in msm-3.10 (yes) QCOM_SCM_SVC_BOOT/0x0a used to be called 'TZBSP_VIDEO_SET_STATE', taking the arguments: args[0] = suspend->0, resume->1 args[1] = spare=0 seems like sdm845/msm-4.9 still had that and so did 8250/msm-4.19 Konrad
