Subject: [PATCH v3 0/5] remoteproc: Add zynqmp_r5 driver

There are Cortex-R5 processors on Xilinx ZynqMP UltraScale+
MPSoC.
This patch is to add an Xilinx ZynqMP R5 remoteproc driver to
enable Linux kernel to bringup R5, and enable communication
between Linux kernel and R5.

There are Cortex-R5 processors on the Xilinx ZynqMP UltraScale+ MPSoC.
This patch adds a Xilinx ZynqMP R5 remoteproc driver to enable the
Linux kernel to bring up the R5s, and to enable communication
between the Linux kernel and R5s.

Ben Levinsky (5):
  firmware: xilinx: Add ZynqMP firmware ioctl enums for RPU
    configuration.
  firmware: xilinx: Add shutdown/wakeup APIs
  firmware: xilinx: Add RPU configuration APIs
  dt-bindings: remoteproc: Add documentation for ZynqMP R5 rproc
    bindings
  remoteproc: Add initial zynqmp R5 remoteproc driver

Changes since v1:
	- remove domain struct as pre review from Matheiu

Changes since v2:
	- update zynqmp_r5 yaml parsing to not raise warnings for extra
	 information in children of R5 node. The warning "node has a unit
	 name, but no reg or ranges property" will still be raised
	 though as this particular node is needed to describe the
	 '#address-cells' and '#size-cells' information.
	- add xilinx-related platform mgmt fn's instead of wrapping around
		function pointer in xilinx eemi ops struct
