The command mode panel should draw image earlier than the display on command execution to prevent showing garbage GRAM screen data. So should set dsi->state as DSIM_STATE_ENABLED between calling exynos_dsi_set_display_enable() and drm_panel_enable() to transmit image data before executing display on command. And moves the display on command execution routine from prepare() to enable() in drm_panel_funcs also.
Applied.
Thanks, Inki Dae
