While the change works fine on imx6dl, it breaks LVDS support on imx6q right away.
imx-ipuv3 2400000.ipu: IPUv3H probed imx-ipuv3 2800000.ipu: IPUv3H probed [drm] Supports vblank timestamp caching Rev 2 (21.10.2013). [drm] No driver support for vblank timestamp query. imx-drm imx-drm.16: bound imx-ipuv3-crtc.0 (ops ipu_crtc_ops) imx-drm imx-drm.16: bound imx-ipuv3-crtc.1 (ops ipu_crtc_ops) imx-drm imx-drm.16: failed to bind ldb.10 (ops imx_ldb_ops): -517
Because we have 4 crtcs for lvds-channel on imx6q while imx-drm master defines only 2 in there, the imx_drm_encoder_parse_of() call from imx_ldb_register() will always return -EPROBE_DEFER.
lvds-channel@0 { crtcs = <&ipu1 0>, <&ipu1 1>, <&ipu2 0>, <&ipu2 1>; };
lvds-channel@1 { crtcs = <&ipu1 0>, <&ipu1 1>, <&ipu2 0>, <&ipu2 1>; };
