Looking and Exynos MIPI DSIM driver, set_blank_mode is handling only FB_BLANK_UNBLANK status, which basically equals to the already existing enable operation, while set_early_blank mode handles only FB_BLANK_POWERDOWN, being equal to disable callback.
Right, exynos_mipi_dsi_blank_mode() only supports FB_BLANK_UNBLANK as of now, but FB_BLANK_NORMAL will be supported in future. If not for Exynos, i think it will be need for other SoCs which support FB_BLANK_UNBLANK and FB_BLANK_NORMAL.
Could you please explain in a bit more details what the set_early_blank_mode and set_blank_mode operations do ?
Both get_frame_done and clear_frame_done do not look at anything used at the moment and if frame done status monitoring will be ever needed, I think a better way should be implemented.
You are right, as of now Exynos MIPI DSI Panels are NOT using these callbacks, but as you mentioned we will need frame done status monitoring anyways, so i included these callbacks here. Will check, if we can implement any better method.
Do you expect the entity drivers (and in particular the panel drivers) to require frame done notification ? If so, could you explain your use case(s) ?
