Hi Inki, On 04/05/2016 10:27 AM, Inki Dae wrote: > This patch cleans up interface type relevant codes. > > Trigger mode is determinded only by i80 mode, which isn't > related to Display types - HDMI or Display controller. > So this patch makes the trigger mode to be set only in case of > i80 mode. With this patch HDMI path image has serious synchronization problems. Exynos5433 documentation says that HDMI Timing Generator generates VSYNC signal which works as a hardware trigger for DECON-TV, so I guess trigger is required. Btw, I think it could be good to remove suffixes I80_RGV from TRIGCON_HWTRIGEN_I80_RGB and TRIGCON_HWTRIGMASK_I80_RGB - they are misleading and differ from documentation. As far as I have tested I80 mode works OK on Decon5433.

This patch cleans up interface type relevant codes. Trigger mode is determinded only by i80 mode, which isn't related to Display types - HDMI or Display controller. So this patch makes the trigger mode to be set only in case of i80 mode.
