Due to the auxiliary register procedure moved to ccu common module,
the auxiliary device id need to be adjusted, otherwise reset driver
will fail to probe.

The above macro is named K1_AUX_DEV_ID(). Why don't you
define K3_AUX_DEV_ID(), which could use "k3" in its name?
Anyway, if you go this route I suggest you drop "K1_" from the
name of this macro.

that should also works, the idea of using same macro '_K_RST()' here
is trying to explictly tell users the clock and reset shares same name

or could further refactor the code, to make K1/K3 drivers share same macro
anyway I don't want to change this patch, my goal here is tring to fix
reset driver after clock common driver refactored plus the modularization
introduced, it's more proper to leave those refactor work up to Guodong,
since he did a lot adjustment to add reset support for K3 SoC

You mean like "spacemit,k1-syscon-mpmu" is used, and you'd rather
name the reset "spacemit.k1-mpmu-reset" because it sort of matches
a little better than "spacemit_ccu_k1.mpmu-reset"?
Anyway, when K1_AUX_DEV_ID() was defined, it was named that way
to suggest a pattern that would mean K3_AUX_DEV_ID() would also
be defined.
I don't really care where the "k1"/"k3" goes, before or after the
period. But I think the "k1" could be encoded explicitly here
rather than doing it with _K_RST() (i.e., don't even use a macro).
