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
