Not necessarily :-) . The GRF is Rockchip's way of not sorting their own invented additional registers. (aka a bunch of registers While on the older models there only ever was the one GRF as dumping ground, newer SoCs now end up with multiple ones :-) These are still iomem areas separate from the actual device-iomem they work with/for but SoCs like the rk3568 now have at least 13 of them. _But_ for the patch in question I fail to see what this set does at all. The rk3568 (only) has XPCS_CON0 and XPCS_STATUS in its PIPE_GRF syscon (according to the TRM), but the patch2 does strange things with offset calculations and names that do not seem to have a match in the TRM. So definitely more explanation on what happens here would be necessary. Heiko
