Hi Nikhil, Thank you for the patch! Perhaps something to improve: [auto build test WARNING on drm-intel/for-linux-next] [also build test WARNING on drm-exynos/exynos-drm-next tegra-drm/drm/tegra/for-next drm-tip/drm-tip linus/master v5.10-rc6 next-20201201] [cannot apply to drm/drm-next] [If your patch is applied to the wrong git tree, kindly drop us a note.

input_bus_flags are specified in drm_bridge_timings (legacy) as well as drm_bridge_state->input_bus_cfg.flags The flags from the timings will be deprecated. Bridges are supposed to validate and set the bridge state flags from atomic_check. Implement atomic_check hook for the same.
