Provide basic driver to control Arm R5 co-processor found on
Xilinx ZynqMP UltraScale+ and Versal MPSoC's.
Currently it is able to start, stop and load elf on to the
processor.
The driver was tested on Xilinx ZynqMP and Versal.
Changes since v1:
- remove domain struct as per review from Mathieu
Changes since v2:
- add xilinx-related platform mgmt fn's instead of wrapping around
function pointer in xilinx eemi ops struct
- 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.
changes since v3:
- add default values for enums
- fix formatting as per checkpatch.pl --strict. Note that 1 warning and 1 check
are still raised as each is due to fixing the warning results in that
particular line going over 80 characters.
- remove warning '/example-0/rpu@ff9a0000/r5@0:
node has a unit name, but no reg or ranges property'
by adding reg to r5 node.
