This series adds ADSP and CDSP remoteproc support, the SPMI PMIC arbiter
and the PMIC descriptions for the Qualcomm Nord platform, and adds the

- Supplies of Nord SoC

  vreg_l7a_1p2     -->  VDD_PX14

Does RPMH require HLOS to cast these votes? Generally such supplies
should be taken care of in the fw

Good point! I just did a couple of tests by:

- dropping regulator-always-on/regulator-boot-on from these regulators
- dropping these regulators completely from DTS

Both booted fine (the nhlos software for Nord Embedded variant are still
under heavy development though).

So what do you prefer, dropping always-on/boot-on property or
the regulators completely?

I think it's best to reach out to the PMIC folks and ask what they think

+Kamal?
