Hi all,
Please ignore this patch because it doesn't work as advertised:
a) Under some circumstance it doesn't do what it claims to do.
b) When it does what it claims to do it hangs the chip on drm-intel-next.
_But_ completely disabling this stuff yields a black screen when enabling
the overlay.
These will be used to ensure that the clock of pipe a is running
when the overlay is switched on. Programming logic more or less
directly ported over from userspace.
Also export the already existing helper function drm_encoder_crtc_ok.
