Message

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

This is based on any code which is not upstream. It means you need to
say what it is your base here.

Thanks,
