[PATCH v4 0/3] drivers: soc: xilinx: Add support for ZynqMP power domain driver

[Jolly Shah]

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.

v4:
 - Added reviewed tag for dt bindings
 - Remove local device list for each domain and use list maintained in core genpd structure
 - Remove hardcoded pd-id to node ID mapping. Instead use argument passed in peripheral node as node ID. 
   Firmware would validate node ID when APIs requested from genpd ops.

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
