I'm still seeing issues with HDMI detect on powerup, at least on my Gateworks Ventana boards (which have no voltage devider or anything else on the HPD line to the IMX6 other than a TVS). I'm currently using your latest imx-drm-staging branch and have applied this patch on top of it. When I enable debug in imx-hdmi.c I see the following:
So it's a similar setup to the Cubox-i.

which is only with imx-hdmi bound, no ldb. The difference you will notice is that there's the "Console: switching ..." line, which is there because I have fbcon enabled.
Therefore, I suspect that it is working as it should - if you enable fbcon, it should automatically initialise. If you don't have fbcon enabled, then it'll probably wait for a userspace DRM driver to bring it up.
Russell,
Yes, your correct. If I enable fbcon it comes up at boot. But what if I don't want fbcon? I have CONFIG_LOGO=y and I would expect that to come up without needing to hotswap. Something must still be missing that is getting taken care of by fbcon.
Thanks,
Tim
