Kernel-4.18.0-80.el8_slim-qcom-ctrl

Qualcomm SLIMbus controller
This controller is used if applications processor driver controls SLIMbus
master component.

Required properties:

  • #address-cells - refer to Documentation/devicetree/bindings/slimbus/bus.txt

  • #size-cells - refer to Documentation/devicetree/bindings/slimbus/bus.txt

  • reg : Offset and length of the register region(s) for the device

  • reg-names : Register region name(s) referenced in reg above
    Required register resource entries are:
    “ctrl”: Physical address of controller register blocks
    “slew”: required for “qcom,apq8064-slim” SOC.

  • compatible : should be “qcom,-slim” for SOC specific compatible

      followed by "qcom,slim" for fallback.
    
  • interrupts : Interrupt number used by this controller

  • clocks : Interface and core clocks used by this SLIMbus controller

  • clock-names : Required clock-name entries are:
    “iface” : Interface clock for this controller
    “core” : Interrupt for controller core’s BAM

Example:

slim@28080000 {
    compatible = "qcom,apq8064-slim", "qcom,slim";
    reg = <0x28080000 0x2000>, <0x80207C 4>;
    reg-names = "ctrl", "slew";
    interrupts = <0 33 0>;
    clocks = <&lcc SLIMBUS_SRC>, <&lcc AUDIO_SLIMBUS_CLK>;
    clock-names = "iface", "core";
    #address-cells = <2>;
    #size-cell = <0>;

    wcd9310: audio-codec@1,0{
        compatible = "slim217,60";
        reg = <1 0>;
    };
};
