+description: |
+ RPMh interconnect providers support system bandwidth requirements through
+ RPMh hardware accelerators known as Bus Clock Manager (BCM). The provider is
+ able to communicate with the BCM through the Resource State Coordinator (RSC)
+ associated with each execution environment. Provider nodes must point to at
+ least one RPMh device child node pertaining to their RSC and each provider
+ can map to multiple RPMh resources.

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@linaro.org> --- 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
