https://git.shady.money/linux/atom?h=v4.72016-04-29T11:22:32Zdrm/arcpgu: use dedicated memory area for frame buffer2016-04-29T11:22:32ZAlexey Brodkinabrodkin@synopsys.com2016-04-27T13:02:39Zurn:sha1:8aeab995fa142523f376369e4ce0608df6727706
Now when ARC supports reserved memory areas and
per-device coherent DMA allocations we may switch ARC PGU
to use of those dedicated areas.
One of the benefits we may move frame-buffer area out
from IO Coherency aperture and so significantly
reduce IOC utilization allowing less demanding
peripherals to use all perks of IOC.

drm: Add support of ARC PGU display controller2016-04-26T14:58:02ZCarlos Palminhapalminha@synopsys.com2016-02-19T12:30:26Zurn:sha1:51dacf208988e5a2561d9b4b560cacc8a7f025e7
ARC PGU could be found on some development boards from Synopsys.
This is a simple byte streamer that reads data from a framebuffer
and sends data to the single encoder.
