Apply analogix_dp_finish_probe() in order to move the panel/bridge parsing from Exynos side to the Analogix side. Signed-off-by: Damon Ding <redacted> Reviewed-by: Dmitry Baryshkov <redacted> Tested-by: Marek Szyprowski <m.szyprowski@samsung.com> --- Changes in v4: - Rename analogix_dp_find_panel_or_bridge() to analogix_dp_finish_probe(). Changes in v7: - Remove exynos_dp_legacy_bridge_init() and inline API devm_drm_of_display_mode_bridge(). - If the panel or the next_bridge is parsed from DT, use ptr validity to check whether to call component_add() directly at the end of probing. --- drivers/gpu/drm/exynos/exynos_dp.c | 19 ++++++++----------- 1 file changed, 8 insertions(+), 11 deletions(-)
