> The zynqmp power domain driver communicates the usage requirements for
> logical power domains / devices to the platform FW.
> FW is responsible for choosing appropriate power states, taking Linux' usage
> information into account.
> 
> This patch series is based on top of Xilinx firmware patch set:
> https://patchwork.kernel.org/cover/10555405/
> 
> v3:
>  - Changed binding to have FW node as a power controller as suggested by Rob
>  - Updated FW driver to register it as mfd child devices from firmware probe
>  - Move bindings location as suggested
> 
> v2:
>  - Rebased on top of latest firmware driver patch series
>  - Updated driver name from zynqmp-genpd to zynqmp-power-controller
>  - Updated device tree bindings to move power controller node under firmware
> node
