    1 Qualcomm SLIMbus controller
    2 This controller is used if applications processor driver controls SLIMbus
    3 master component.
    4 
    5 Required properties:
    6 
    7  - #address-cells - refer to Documentation/devicetree/bindings/slimbus/bus.txt
    8  - #size-cells  - refer to Documentation/devicetree/bindings/slimbus/bus.txt
    9 
   10  - reg : Offset and length of the register region(s) for the device
   11  - reg-names : Register region name(s) referenced in reg above
   12          Required register resource entries are:
   13          "ctrl": Physical address of controller register blocks
   14          "slew": required for "qcom,apq8064-slim" SOC.
   15  - compatible : should be "qcom,<SOC-NAME>-slim" for SOC specific compatible
   16                 followed by "qcom,slim" for fallback.
   17  - interrupts : Interrupt number used by this controller
   18  - clocks : Interface and core clocks used by this SLIMbus controller
   19  - clock-names : Required clock-name entries are:
   20         "iface" : Interface clock for this controller
   21         "core" : Interrupt for controller core's BAM
   22 
   23 Example:
   24 
   25         slim@28080000 {
   26                 compatible = "qcom,apq8064-slim", "qcom,slim";
   27                 reg = <0x28080000 0x2000>, <0x80207C 4>;
   28                 reg-names = "ctrl", "slew";
   29                 interrupts = <0 33 0>;
   30                 clocks = <&lcc SLIMBUS_SRC>, <&lcc AUDIO_SLIMBUS_CLK>;
   31                 clock-names = "iface", "core";
   32                 #address-cells = <2>;
   33                 #size-cell = <0>;
   34 
   35                 wcd9310: audio-codec@1,0{
   36                         compatible = "slim217,60";
   37                         reg = <1 0>;
   38                 };
   39         };
