[PATCH 0/2] soc: amlogic: add support for the Meson AXG Power Controller

[Neil Armstrong]

This adds the bindings and support for the Power Controller found in the
Amlogic AXG SoCs.

The Power Controller in the Amlogic AXG SoCs is similar to the GXL one
but with less VPU memory domains to enable and a supplementary Audio
memory power domain.
