Sorry, Philipp. The setup in my report is incorrect. The correct setup to see this issue consists of:
build a kernel without HDMI support, i.e. !CONFIG_DRM_IMX_HDMI
enable HDMI device in DT, i.e. adding the lines below in board dts.
&hdmi { status = "okay"; };
Sorry for the confusion.
This isn't a supported use-case, the componentized device stuff is there exactly to ensure that the DRM device is only brought up after all active components have an driver attached to them.
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.
