drm/imx: parallel-display: fix drm_panel support
The parallel-display driver used an undocumented, non-standard property "fsl,panel" to optionally associate with a drm_panel device. This patch fixes the driver to use the same OF graph bindings as the LDB driver instead: parallel-display { compatible = "fsl,imx-parallel-display"; ... port@1 { reg = <1>; parallel_out: endpoint { remote_endpoint = <&panel_in>; }; }; }; panel { ... port { panel_in: endpoint { remote-endpoint = <&parallel_out>; }; }; }; Signed-off-by: Philipp Zabel <p.zabel@pengutronix.de> Tested-by: Gary Bisson <gary.bisson@boundarydevices.com>
