By default, the hwmod code assumes that interface clocks can be autoidled by the PRCM. When the interface clock can't be autoidled by the PRCM, those interfaces must be marked with the OCPIF_SWSUP_IDLE flag. Otherwise, the "interface clock" will always have a non-zero use count, and the device won't enter idle. This problem was observed on N8x0. Fix the immediate problem by marking the VENC interface with the OCPIF_SWSUP_IDLE flag. But it's not clear that "dss_54m_fck"/"dss_tv_fck" is really the correct interface clock for VENC. It may be that the VENC interface should use a hardware-autoidling interface clock. This is the situation on OMAP4, which uses "l3_div_ck" as the VENC interface clock, which can be autoidled by the PRCM. Clarification from TI is needed.
