-Qualcomm SLIMbus controller
-This controller is used if applications processor driver controls SLIMbus
-master component.
-
-Required properties:
-
- - 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@...80000 {
- 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>;
- };
- };
