Represent the RPU domain resources in one device node. Each RPU processor is a subnode of the top RPU domain node. Signed-off-by: Ben Levinsky Signed-off-by: Jason Wu Signed-off-by: Wendy Liang Signed-off-by: Michal Simek --- 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. Changes since 3: - 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. --- .../remoteproc/xilinx,zynqmp-r5-remoteproc.yaml | 127 +++++++++++++++++++++ 1 file changed, 127 insertions(+) create mode 100644 Documentation/devicetree/bindings/remoteproc/xilinx,zynqmp-r5-remoteproc.yaml diff --git a/Documentation/devicetree/bindings/remoteproc/xilinx,zynqmp-r5-remoteproc.yaml b/Documentation/devicetree/bindings/remoteproc/xilinx,zynqmp-r5-remoteproc.yaml new file mode 100644 index 0000000..41520b6 --- /dev/null +++ b/Documentation/devicetree/bindings/remoteproc/xilinx,zynqmp-r5-remoteproc.yaml @@ -0,0 +1,127 @@ +# SPDX-License-Identifier: (GPL-2.0 OR BSD-2-Clause) +%YAML 1.2 +--- +$id: "http://devicetree.org/schemas/remoteproc/xilinx,zynqmp-r5-remoteproc.yaml#" +$schema: "http://devicetree.org/meta-schemas/core.yaml#" + +title: Xilinx R5 remote processor controller bindings + +description: + This document defines the binding for the remoteproc component that loads and + boots firmwares on the Xilinx Zynqmp and Versal family chipset. + +maintainers: + - Ed Mooring + - Ben Levinsky + +properties: + compatible: + const: "xlnx,zynqmp-r5-remoteproc-1.0" + + core_conf: + description: + R5 core configuration (valid string - split or lock-step) + maxItems: 1 + + interrupts: + description: + Interrupt mapping for remoteproc IPI.
