Signed-off-by: Jason Wu Signed-off-by: Wendy Liang Signed-off-by: Michal Simek Signed-off-by: Ben Levinsky --- v3: - 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:: - 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 v6: - remove coupling TCM nodes with remoteproc - remove mailbox as it is optional not needed v7: - change lockstep-mode to xlnx,cluster-mode v9: - show example IPC nodes and tcm bank nodes v11: - add property meta-memory-regions to illustrate link between r5 and TCM banks - update so no warnings from 'make dt_binding_check' v14: - concerns were raised about the new property meta-memory-regions. There is no clear direction so for the moment I kept it in the series - place IPC nodes in RAM in the reserved memory section v15: - change lockstep-mode prop as follows: if present, then RPU cluster is in lockstep mode. if not present, cluster is in split mode. --- .../xilinx,zynqmp-r5-remoteproc.yaml | 120 ++++++++++++++++++ 1 file changed, 120 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 000000000000..ce02e425692e --- /dev/null +++ b/Documentation/devicetree/bindings/remoteproc/xilinx,zynqmp-r5-remoteproc.yaml @@ -0,0 +1,120 @@ +# 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. + + Note that the Linux has global addressing view of the R5-related memory (TCM) + so the absolute address ranges are provided in TCM reg's. +maintainers: + - Ed Mooring + - Ben Levinsky + +properties: + compatible: + const: "xlnx,zynqmp-r5-remoteproc-1.0" + + lockstep-mode: + description: + If this property is present, then the configuration is lock-step. + Otherwise RPU is split. + maxItems: 1 + + interrupts: + description: + Interrupt mapping for remoteproc IPI.
