The dw-hdmi driver switched to regmap-mmio, but lacks the dependency in

Archit,

This is a v4.12 regression fix. While not super critical, it would be
nice if it could get merged in v4.12.

Sean,

Would you be fine with another drm-misc-fixes pull req? It looks like
we have a drm_of_find_panel_or_bridge() usage on imx which needs fixing
too. If so, I can queue this to drm-misc-fixes.

Thanks,
Archit
