Unfortunately there's no DRM ARC PGU driver at the moment. We still only have ARC PGU driver as a part of off-the-tree arc-3.18 branch, see https://github.com/foss-for-synopsys-dwc-arc-processors/linux/blob/arc-3.18/drivers/video/fbdev/arcpgu.c And without PGU driver that ADI I2C is useless because this interface is only used in HDMI for control data exchange like display mode setting etc. Once we upstream ARC PGU driver (we plan to do it in 4.6/4.7 timeframe) that change will make perfect sense. So for now we won't accept that patch. Still if you want to help us with ARC PGU upstreaming please feel free to use mentioned implementation as a reference and create your clean implementation basing on linux-next. If you're going to do that please let me know so we don't do the same work twice. -Alexey ^ permalink raw reply [flat|nested] 2+ messages in thread

Unfortunately no ARC PGU-related patches have been sent upstream yet. -Alexey ^ permalink raw reply [flat|nested] 2+ messages in thread
