[PATCH 0/4] Switch Nord CDSPs onto NMXC power domain

[Shawn Guo]

The Nord CDSP subsystems do not take their memory rail from the shared
MX rail like all other Qualcomm SoCs, but from a dedicated NMXC RPMh
resource. Nord's initial PAS support was merged with "mx" in the proxy
power domain list, which leaves CDSPs relying on other components to
vote on NMXC rail.

The first two pmdomain patches add the NMXC domain index and register
the nmxc.lvl resource in the Nord rpmhpd table. The other two remoteproc
patches correct the Nord PAS binding and driver to name "nmxc" instead of
"mx" for CDSPs, so that the right rail is held during PAS authentication
and boot.

The pmdomain and remoteproc changes can be applied independently -- only
the power domain name string changes on the remoteproc side, so there is
no build dependency between the two halves. I send them as one series to
demonstrate this is fixing "one problem". I can split if needed.

There is no ABI concern: no in-tree device tree references the Nord CDSPs
yet.
