This series adds support for the power domains on Google GS101.

There are a few differences compared to SoCs already supported by this
driver:
* register access does not work via plain ioremap() / readl() /
  writel().
  Instead, the regmap created by the PMU driver must be used (which
  uses Arm SMCC calls under the hood).
* DTZPC: a call needs to be made before and after power domain off/on,
  to inform the EL3 firmware of the request.
* power domains can and are fed by a regulator rail and therefore
  regulator control needed be implemented.

[...]
Applied, thanks!

Best regards,
Usually I pick up the power-domain related changes for the DT bindings
and host them via an immutable branch called "dt". If needed, SOC
maintainers can pull it to apply/test the corresponding DTS changes.

That said, I am open to whatever you think is best here. Perhaps it's
easier if you can drop the DT patches and provide your acks instead or
if you can share them via an immutable branch for me to pull?

Kind regards
Uffe
