Hi,
In Table 18-28. Reset Sources Overview of DM8168 TRM, I only found DSS_M3_RST1/2/3. I think it is to reset hdvpss M3. In TRM, I also found RM_DEFAULT_RSTCTRL.RST3/M3_RST2/M3_RST1. Are these registers only for hdvpss M3 or some is for video M3? If these registers can't reset video M3, do you have any suggestion on how to reset video M3?
