    Subject[PATCH v6 0/5] Provide basic driver to control Arm R5 co-processor found on
    Date
    Currently it is able to start, stop and load elf on to the
    processor.

    The driver was tested on Xilinx ZynqMP and Versal.

    v2:
    - remove domain struct as per review from Mathieu
    v3:
    - 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.
    v4:
    - 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.
    v5:
    - update device tree sample and yaml parsing to not raise any warnings
    - description for memory-region in yaml parsing
    - compatible string in yaml parsing for TCM
    - parse_fw change from use of rproc_of_resm_mem_entry_init to rproc_mem_entry_init and use of alloc/release
    - var's of type zynqmp_r5_pdata all have same local variable name
    - use dev_dbg instead of dev_info
    v6:
    - adding memory carveouts is handled much more similarly. All mem carveouts are
    now described in reserved memory as needed. That is, TCM nodes are not
    coupled to remoteproc anymore. This is reflected in the remoteproc R5 driver
    and the device tree binding.
    - remove mailbox from device tree binding as it is not necessary for elf
    loading



    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
