This series parses one of the dark corners of the EDID to expose "4k x 2k"
modes to userspace. Those modes are part of HDMI 1.4.
To complete the 4k HDMI support, one needs:
* Hardware able to output a 300 MHz TMDS clock (Haswell can do that) and
Daniel's patch to bump that limit in the kernel (already queued).
