Yes.  How about if sunxi_hdmi_hpd_detect() was split into two, firstly the
initialisation part that always needs to be run, and secondly the actual
hpd detection, which would only be run if the hpd option to video-mode was
selected?

Another idea is that the hpd timeout value could be an additional option to
video-mode.

Thanks,
B.R.
