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. --- v7: Fix macro names in dt-bindings header Do clock get in icc driver v6: Removed 'Reviewed-by: Krzysztof' from dt-bindings patch Remove clock get from ICC driver as suggested by Stephen Boyd so that the actual peripheral can do the clock get first_id -> icc_first_node_id Remove tristate from INTERCONNECT_CLK v5: Split gcc-ipq9574.c and common.c changes into separate patches Introduce devm_icc_clk_register Fix error handling 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 (5): dt-bindings: interconnect: Add Qualcomm IPQ9574 support interconnect: icc-clk: Add devm_icc_clk_register clk: qcom: common: Add interconnect clocks support clk: qcom: ipq9574: Use icc-clk for enabling NoC related clocks 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 | 31 ++++++- drivers/clk/qcom/common.h | 3 + drivers/clk/qcom/gcc-ipq9574.c | 30 +++++++ drivers/interconnect/icc-clk.c | 18 ++++ .../dt-bindings/interconnect/qcom,ipq9574.h | 87 +++++++++++++++++++ include/linux/interconnect-clk.h | 2 + 9 files changed, 177 insertions(+), 1 deletion(-) create mode 100644 include/dt-bindings/interconnect/qcom,ipq9574.h
