Ah, yes. I was in the impression that LVDS should still work in this
setup, but that was the case before Philipp's series. In Russell's
original imx-drm setup, LVDS still works even if I enable the HDMI
device in DT, as long as I do not reference it from 'connectors'.
imx_drm: imx-drm {
compatible = "fsl,imx-drm";
crtcs = <&ipu1 0>, <&ipu1 1>;
connectors = <&ldb>;
};
Thanks for the clarification.
