As I stated before I would like for you to use the existing rproc_list,
as done in rproc_get_by_phandle() today.
But as you resend this patch, could you please make this check fallback
to also checking for "ti,rproc", then simply drop the existing
rproc_get_by_phandle() and change the call to
of_rproc_byindex(dev->of_node, 0) in wkup_m3_ipc.c?
That way we're backwards compatible with the TI wakeup M3, without
having to maintain the then non-standard generic rproc phandle resolver.
