[PATCH 0/3] pmdomain: qcom: rpmhpd: Add power domains for Nord SoC

[Shawn Guo]

This series adds RPMh power domain support for the Qualcomm Nord SoC.

The Nord SoC introduces two new power domains beyond the existing set: GFX1
for the second GFX subsystem and NSP3 for the fourth NSP subsystem.  Patch 1
is a preparatory cleanup that fixes inconsistent whitespace in the RPMHPD
define block before the new entries are added.  Patches 2-3 add the DT
bindings and driver support for Nord respectively.

[PATCH 1/3] dt-bindings: power: qcom,rpmhpd: Fix whitespace in RPMHPD defines

[Shawn Guo]

Some RPMHPD_* defines in the Generic RPMH Power Domain Indexes section
were using spaces instead of tabs for alignment. Fix them to be
consistent with the rest of the file.
