MSM platforms manage NoC related clocks and scaling from RPM. However, in IPQ SoCs, RPM is not involved in managing NoC related clocks and there is no NoC scaling. However, there is a requirement to enable some NoC interface clocks for the accessing the peripherals present in the system. Hence add a minimalistic interconnect driver that establishes a path from the processor/memory to those peripherals and vice versa. --- v4: gcc-ipq9574.c Use clk_hw instead of indices common.c Do icc register in qcom_cc_probe() call stream common.h Add icc clock info to qcom_cc_desc structure v3: qcom,ipq9574.h Move 'first id' define to clock driver gcc-ipq9574.c: Use indexed identifiers here to avoid confusion Fix error messages and move code to common.c as it can be shared with future SoCs v2: qcom,ipq9574.h Fix license identifier Rename macros qcom,ipq9574-gcc.yaml Include interconnect-cells gcc-ipq9574.c Update commit log Remove IS_ENABLED(CONFIG_INTERCONNECT) and auto select it from Kconfig ipq9574.dtsi Moved to separate patch Include interconnect-cells to clock controller node drivers/clk/qcom/Kconfig: Auto select CONFIG_INTERCONNECT & CONFIG_INTERCONNECT_CLK Varadarajan Narayanan (3): dt-bindings: interconnect: Add Qualcomm IPQ9574 support clk: qcom: add IPQ9574 interconnect clocks support arm64: dts: qcom: ipq9574: Add icc provider ability to gcc .../bindings/clock/qcom,ipq9574-gcc.yaml | 3 + arch/arm64/boot/dts/qcom/ipq9574.dtsi | 2 + drivers/clk/qcom/Kconfig | 2 + drivers/clk/qcom/common.c | 34 ++++++++++- drivers/clk/qcom/common.h | 4 +- drivers/clk/qcom/gcc-ipq9574.c | 54 +++++++++++++++++ .../dt-bindings/interconnect/qcom,ipq9574.h | 59 +++++++++++++++++++ 7 files changed, 156 insertions(+), 2 deletions(-) create mode 100644 include/dt-bindings/interconnect/qcom,ipq9574.h -- 2.34.1
