This needs a matching change to the DT bindings.

However, please take a look at Angelo's recent series [1] for MT8196
PMICs that also adds variants of the MT6316 series regulators and how
it adds compatible strings for various parts to cover 2-phase, 3-phase,
and 4-phase settings.

Now personally I think a better way would be if we could somehow read back
a) the part number, or b) the multi-phase settings from the chip itself,
and derive `modeset_mask` automatically. Is that possible? Can MediaTek
share this information?

You can fully reuse mt8195_regs, as mt8189 has the same layout.

Why are you avoiding to enable the INT1 interrupt on MT8189?

Is this working around a hardware bug, or did you simply forget to enable it?
I think you should really enable it, which means....

...means that you don't even need to add a new compatible in this list, because
the MT8195 compatible can be reused.

You only have to add the MT8189 compatible to the bindings, so that you are
allowed to specify in your devicetree node

compatible = "mediatek,mt8189-pwrap", "mediatek,mt8195-pwrap";

This change is useless. Just add the compatible to the bindings so that you
can specify

compatible = "mediatek,mt8189-spmi", "mediatek,mt8195-spmi";

The changes look good, but you have to split the commit in two; one for adding the
compatible to mediatek,pwrap.yaml and one for adding it to the other.

Besides, please check the git log for both yaml files and:
  1. Use the same prefixes that you find in there for your new commit titles;
  2. Add a commit description that describes your change, e.g.:
     "Add a new compatible string for MT8189; this SoC's {spmi, pwrap} IP is fully
      compatible with the one found in the MT8195 SoC."

Angelo
