So it depends if > people want to phase them out or not. FWIW, any Chrome{device} using these sort of bindings is perfectly capable of handling changed bindings (we ship DTBs with the kernel). But that's not typically how mainline covers binding deprecation. If we're going to start recommending not putting these offsets in the DT, I'd vote for deprecating them, for consistency. (Otherwise, we'll keep running into this same question.) We only documented the RK3399 ("rockchip,rk3399-typec-phy") binding, so all users should have the same offsets. I dunno if/how we pick a time for eventually removing the bindings entirely.

For what it's worth I run mainline on my Chromebook Plus (rk3399-gru-kevin), but in order to have a somewhat working setup you need to run 4.16-rc1 + various patches from the rockchip mailing list which means you have to keep up with the latest mainline (both kernel and devicetree) anyway.

GRF reg offset in that case but matching against the base address for the type-c phy should therefore be fine as well.
