Changes since v7: - Rebase to kernel 5.16 - Add tags of reviewed-by and acked-by. - Add detailed commit message for flag "hs_packet_end_aligned" in DSI common driver. Changes since v6: - Add "bool hs_packet_end_aligned" in "struct mipi_dsi_device" to control the dsi aligned. - Config the "hs_packet_end_aligned" in ANX7725 .attach(). Changes since v5: - Search the anx7625 compatible as flag to control dsi output aligned. Changes since v4: - Move "dt-bindings: drm/bridge: anx7625: add force_dsi_end_without_null" before "drm/mediatek: force hsa hbp hfp packets multiple of lanenum to avoid". - Retitle "dt-bindings: drm/bridge: anx7625: add force_dsi_end_without_null".
