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.
