Shouldn't this go via GPIO tree?

Yeah. Actually, you can ignore this patch, as I already sent two separate patches for this: https://lore.kernel.org/lkml/20201119170901.GA22703@embeddedor/ https://lore.kernel.org/lkml/20201119170739.GA22665@embeddedor/ I noticed this immediately after sending this out. Thanks -- Gustavo

In preparation to enable -Wimplicit-fallthrough for Clang, fix multiple warnings by explicitly adding a break and a fallthrough statements instead of just letting the code fall through to the next case.
