Currently, the Northwest Logic MIPI-DSI controller host specific code resides under drm/bridge, but is not a real drm_bridge. It creates a drm_bridge and adds itself to the drm_encoder that handles this file, but this is wrong, since it does not implement the drm_bridge_funcs. The correct way to implement a drm_bridge is to add the drm_bridge and let other components (another bridge or a drm_encoder) to attach to this bridge. Since we are doing this, a new compatible strings can be used for this driver: "nwl,mipi-dsi". Since this was used by nwl_dsi-imx.c, update that driver to use this bridge correctly. This is needed in order to add support for MIPI-DSI on 8MQ. The IMX_NWL driver will either add a DSI encoder to DRM, or a DSI bridge. The encoder will be used by imx-drm-core driver, while the bridge will be used by MXSFB driver (which creates a simple display pipe). Signed-off-by: Robert Chiras <robert.chiras@nxp.com>
