-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-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 <dt-bindings/mfd/arizona.txt>. 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/wlf,arizona.txt
-
-Example:
-
-codec: wm5102@1a {
- compatible = "wlf,wm5102";
- reg = <0x1a>;
- interrupts = <347>;
- interrupt-controller;
- #interrupt-cells = <2>;
