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,<SOC-NAME>-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>;
};
};
