Signed-off-by: Brian Masney Reviewed-by: Rob Herring Reviewed-by: Bjorn Andersson --- Rob: I included in the next patch at the top a rough diagram showing the relationship between different buses. I wanted to include that diagram here, however I didn't since I assume that this document will be transformed into HTML. I've seen some of the text bindings in the IIO subsystem have nice ASCII-art diagrams, such as Documentation/devicetree/bindings/iio/dac/dpot-dac.txt. Do you have any suggestions for how this can go in the YAML bindings? Prefix the line with four spaces, similiar to what is done in markdown? Changes since v1: - Don't include all compatibles in the examples. Removed interconnect GPU client from example as well. - Dual license header file: BSD or GPL 2.0 .../bindings/interconnect/qcom,msm8974.yaml | 62 ++++++++ .../dt-bindings/interconnect/qcom,msm8974.h | 146 ++++++++++++++++++ 2 files changed, 208 insertions(+) create mode 100644 Documentation/devicetree/bindings/interconnect/qcom,msm8974.yaml create mode 100644 include/dt-bindings/interconnect/qcom,msm8974.h diff --git a/Documentation/devicetree/bindings/interconnect/qcom,msm8974.yaml b/Documentation/devicetree/bindings/interconnect/qcom,msm8974.yaml new file mode 100644 index 000000000000..9af3c6e59cff --- /dev/null +++ b/Documentation/devicetree/bindings/interconnect/qcom,msm8974.yaml @@ -0,0 +1,62 @@ +# SPDX-License-Identifier: (GPL-2.0 OR BSD-2-Clause) +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/interconnect/qcom,msm8974.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: Qualcomm MSM8974 Network-On-Chip Interconnect + +maintainers: + - Brian Masney + +description: | + The Qualcomm MSM8974 interconnect providers support setting system + bandwidth requirements between various network-on-chip fabrics. + +properties: + reg: + maxItems: 1 + + compatible: + enum: + - qcom,msm8974-bimc + - qcom,msm8974-cnoc + - qcom,msm8974-mmssnoc + - qcom,msm8974-ocmemnoc + - qcom,msm8974-pnoc + - qcom,msm8974-snoc + + '#interconnect-cells': + const: 1 + + clock-names: + items: + - const: bus + - const: bus_a + + clocks: + items: + - description: Bus Clock + - description: Bus A Clock + +required: + - compatible + - reg + - '#interconnect-cells' + - clock-names + - clocks + +additionalProperties: false + +examples: + - | + #include + + bimc: interconnect@fc380000 { + reg = <0xfc380000 0x6a000>;
