The Qualcomm SM8550 SoC has several bus fabrics that could be controlled and tuned dynamically according to the bandwidth demand. Signed-off-by: Abel Vesa <abel.vesa@xxxxxxxxxx> --- Changes since v2: * Added Neil and I as maintainers in the binding doc, as Krzysztof suggested * Added top-level reg property witg maxItem 1 * Fixed the if clause for reg property, like Krzysztof suggested * Added top-level clocks, along with dedicated if clause for clocks property for required/false, like Krzysztof suggested * Kept only clk_virt and aggre1 examples and dropped the rest * Renamed both header and bindings like the compatible * Squashed the bindings schema patch in the one with the header .../interconnect/qcom,sm8550-rpmh.yaml | 139 +++++++++++++ .../interconnect/qcom,sm8550-rpmh.h | 190 ++++++++++++++++++ 2 files changed, 329 insertions(+) create mode 100644 Documentation/devicetree/bindings/interconnect/qcom,sm8550-rpmh.yaml create mode 100644 include/dt-bindings/interconnect/qcom,sm8550-rpmh.h diff --git a/Documentation/devicetree/bindings/interconnect/qcom,sm8550-rpmh.yaml b/Documentation/devicetree/bindings/interconnect/qcom,sm8550-rpmh.yaml new file mode 100644 index 000000000000..785465926db9 --- /dev/null +++ b/Documentation/devicetree/bindings/interconnect/qcom,sm8550-rpmh.yaml @@ -0,0 +1,139 @@ +# SPDX-License-Identifier: (GPL-2.0 OR BSD-2-Clause) +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/interconnect/qcom,sm8550-rpmh.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: Qualcomm RPMh Network-On-Chip Interconnect on SM8550 + +maintainers: + - Abel Vesa <abel.vesa@xxxxxxxxxx> + - Neil Armstrong <neil.armstrong@xxxxxxxxxx> + +description: | + RPMh interconnect providers support system bandwidth requirements through + RPMh hardware accelerators known as Bus Clock Manager (BCM).
