Turned out, the built-in chip select always gets activated at the moment even if a gpio-cs is being used. With that fixed, I noticed that any read with multiple data lines was not working properly, so patch two changes how the driver deals with emulating mem-ops. The remaining patches are things I consider fixes but not meaningful enough to get a Fixes tag. LMK if you want em split out to be put on for-next rather than for-current. Cheers, Conor.
