Cirrus Logic/Wolfson Microelectronics Arizona class audio SoCs These devices are audio SoCs with extensive digital capabilities and a range of analogue I/O. Required properties: - compatible : One of the following chip-specific strings: "cirrus,cs47l24" "wlf,wm5102" "wlf,wm5110" "wlf,wm8280" "wlf,wm8997" "wlf,wm8998" "wlf,wm1814" "wlf,wm1831" - reg : I2C slave address when connected using I2C, chip select number when using SPI. - interrupts : The interrupt line the /IRQ signal for the device is connected to. - interrupt-controller : Arizona class devices contain interrupt controllers and may provide interrupt services to other devices. - interrupt-parent : The parent interrupt controller. - #interrupt-cells: the number of cells to describe an IRQ, this should be 2. The first cell is the IRQ number. The second cell is the flags, encoded as the trigger masks from Documentation/devicetree/bindings/interrupt-controller/interrupts.txt - gpio-controller : Indicates this device is a GPIO controller. - #gpio-cells : Must be 2. The first cell is the pin number and the second cell is used to specify optional parameters, see ../gpio/gpio.txt for details. - AVDD-supply, DBVDD1-supply, CPVDD-supply : Power supplies for the device, as covered in Documentation/devicetree/bindings/regulator/regulator.txt - DBVDD2-supply, DBVDD3-supply : Additional databus power supplies (wm5102, wm5110, wm8280, wm8998, wm1814) - SPKVDDL-supply, SPKVDDR-supply : Speaker driver power supplies (wm5102, wm5110, wm8280, wm8998, wm1814) - SPKVDD-supply : Speaker driver power supply (wm8997) - DCVDD-supply : Main power supply (cs47l24, wm1831) - MICVDD-supply : Microphone power supply (cs47l24, wm1831) Optional properties: - reset-gpios : GPIO specifier for the GPIO controlling /RESET - clocks: Should reference the clocks supplied on MCLK1 and MCLK2 - clock-names: Should contains two strings: "mclk1" for the clock supplied on MCLK1, recommended to be a high quality audio reference clock "mclk2" for the clock supplied on MCLK2, recommended to be an always on 32k clock - wlf,gpio-defaults : A list of GPIO configuration register values. Defines for the appropriate values can found in . If absent, no configuration of these registers is performed. If any entry has a value that is out of range for a 16 bit register then the chip default will be used. If present exactly five values must be specified. - DCVDD-supply, MICVDD-supply : Power supplies, only need to be specified if they are being externally supplied. As covered in Documentation/devicetree/bindings/regulator/regulator.txt (wm5102, wm5110, wm8280, wm8997, wm8998, wm1814) Deprecated properties: - wlf,reset : GPIO specifier for the GPIO controlling /RESET Also see child specific device properties: Regulator - ../regulator/arizona-regulator.txt Extcon - ../extcon/extcon-arizona.txt Sound - ../sound/arizona.txt Example: codec: wm5102@1a { compatible = "wlf,wm5102"; reg = <0x1a>; interrupts = <347>; interrupt-controller; #interrupt-cells = <2>; interrupt-parent = <&gic>; gpio-controller; #gpio-cells = <2>; wlf,gpio-defaults = < ARIZONA_GP_FN_TXLRCLK ARIZONA_GP_DEFAULT ARIZONA_GP_DEFAULT ARIZONA_GP_DEFAULT ARIZONA_GP_DEFAULT >; };
