[v2,0/2] interconnect: qcom: add msm8974 support

Message

Here's a patch series that adds interconnect support for the Qualcomm
MSM8974, which is needed so that the GPU can be supported upstream.

I didn't include the changes to arch/arm/boot/dts/qcom-msm8974.dtsi
since I have some other device tree patches coming. I'll send them
all out in a single series once rc4 comes out to avoid any merge
conflicts. Here's the necessary nodes that need to be added to that
file:

  #include <dt-bindings/interconnect/qcom,msm8974.h>

  bimc: interconnect@fc380000 {
          reg = <0xfc380000 0x6a000>;
          compatible = "qcom,msm8974-bimc";
          #interconnect-cells = <1>;
          clock-names = "bus", "bus_a";
          clocks = <&rpmcc RPM_SMD_BIMC_CLK>,
                   <&rpmcc RPM_SMD_BIMC_A_CLK>;
  };

  cnoc: interconnect@fc480000 {
          reg = <0xfc480000 0x4000>;
          compatible = "qcom,msm8974-cnoc";
          #interconnect-cells = <1>;
          clock-names = "bus", "bus_a";
          clocks = <&rpmcc RPM_SMD_CNOC_CLK>,
                   <&rpmcc RPM_SMD_CNOC_A_CLK>;
  };

  mmssnoc: interconnect@fc478000 {
          reg = <0xfc478000 0x4000>;
          compatible = "qcom,msm8974-mmssnoc";
          #interconnect-cells = <1>;
          clock-names = "bus", "bus_a";
          clocks = <&mmcc MMSS_S0_AXI_CLK>,
                   <&mmcc MMSS_S0_AXI_CLK>;
  };

  ocmemnoc: interconnect@fc470000 {
          reg = <0xfc470000 0x4000>;
          compatible = "qcom,msm8974-ocmemnoc";
          #interconnect-cells = <1>;
          clock-names = "bus", "bus_a";
          clocks = <&rpmcc RPM_SMD_OCMEMGX_CLK>,
                   <&rpmcc RPM_SMD_OCMEMGX_A_CLK>;
  };

  pnoc: interconnect@fc468000 {
          reg = <0xfc468000 0x4000>;
          compatible = "qcom,msm8974-pnoc";
          #interconnect-cells = <1>;
          clock-names = "bus", "bus_a";
          clocks = <&rpmcc RPM_SMD_PNOC_CLK>,
                   <&rpmcc RPM_SMD_PNOC_A_CLK>;
  };

  snoc: interconnect@fc460000 {
          reg = <0xfc460000 0x4000>;
          compatible = "qcom,msm8974-snoc";
          #interconnect-cells = <1>;
          clock-names = "bus", "bus_a";
          clocks = <&rpmcc RPM_SMD_SNOC_CLK>,
                   <&rpmcc RPM_SMD_SNOC_A_CLK>;
  };
