Intel DRM Driver Prepping For HDMI 2.0 With Geminilake

Our alternative OS friends over at Phoronix have the lowdown on six new patches that support the native HDMI 2.0 controller in Intel's upcoming Geminilake hardware.

Six patches posted today are for enabling HDMI 2.0 scrambling in the DRM layer. Scrambling though, fortunately, isn't DRM related as it may sound. Shashank Sharma of Intel explained, "HDMI 2.0 spec defines a method to reduce the RF footprint while operating at higher pixel clocks, which is called Scrambling. Scrambling can be controlled over a new set of I2C registers which are accessible over existing DDC I2C lines, called SCDC register set."
