See Justin Swartz > recent patches for rk3228. Thanks for the instruction! I've been a bit confused about that because RK3399 has its own compatible (without a 2nd rk3288 compatible) although there's nothing different with it either. All of these rockchip platforms come with what they call "RGA2", th= at seems to have no variation across platforms (downstream rockchip even has a single compatible for it). Should we add the rk3288 compatible to the rk3399 dtsi? I guess we can't remove it from the driver at this point, for backward compatibility with previous dts (what a strange idea...). > Down the road, if you find something specific for px30, > you can make the driver aware.=20 Makes sense, yes.
