New DRM Driver Set For Linux 4.7: ARC PGU

David Airlie has pulled the ARC PGU DRM driver into his DRM-Next tree for in turn landing with the Linux 4.7 kernel.

The ARC PGU DRM driver is for a simple display controller found on Synopsys development boards. The ARC PGU is an RGB streamer that reads from a frame-buffer and sends to a digital (HDMI) encoder. This ARC PGU hardware is found on Synopsys boards like the AXS101 and AXS103.

I doubt many Phoronix readers have such development boards around, but it's great nevertheless seeing more companies get involved in providing mainline DRM kernel drivers. If you want to learn more or dig through the code for this small driver, see this Git commit that landed the less than thousand lines of code driver into the DRM tree.
