[PATCH 0/5] arm64: meson: add support for SM1 Power Domains

[Neil Armstrong]

This patchset introduces a new "Everything-Else Power Domain Controller"
designed to handle all the different non-Always On peripherals like :
- VPU
- Ethernet Memories
- USB, PCIe, Audio, NNA on SM1

The current "gx-vpu-pwrc" process has been integrated to support the VPU
and the other power domains in a single driver.

Support for SoC domains has been made generic and easily extendable.

In order to restart from clean architecture :
- the PWRC node has been moved into the HHI simple-mfd, this suits much
  better than beeing in the AO RTI simple-mfd
- a brand new yaml bindings schemas has been written
- reset-names has been added to clarify which resets are needed, so we can
  dispatch them to domains

For G12A, the PWRC now offers support for the ethmac memory power domain.

For SM1, it also offers support for PCIe, USB, NNA, ethmac and Audio power
domains.

The DOS domains has been excluded for now, but can be added very easily.

GX hasn't been integrated for now, but it would follow the same scheme
as G12A support.
