1 Cirrus Logic/Wolfson Microelectronics Arizona class audio SoCs
3 These devices are audio SoCs with extensive digital capabilities and a range
8 - compatible : One of the following chip-specific strings:
18 - reg : I2C slave address when connected using I2C, chip select number when
21 - interrupts : The interrupt line the /IRQ signal for the device is
23 - interrupt-controller : Arizona class devices contain interrupt controllers
24 and may provide interrupt services to other devices.
25 - #interrupt-cells: the number of cells to describe an IRQ, this should be 2.
26 The first cell is the IRQ number.
27 The second cell is the flags, encoded as the trigger masks from
28 Documentation/devicetree/bindings/interrupt-controller/interrupts.txt
30 - gpio-controller : Indicates this device is a GPIO controller.
31 - #gpio-cells : Must be 2. The first cell is the pin number and the
32 second cell is used to specify optional parameters, see ../gpio/gpio.txt
35 - AVDD-supply, DBVDD1-supply, CPVDD-supply : Power supplies for the device,
36 as covered in Documentation/devicetree/bindings/regulator/regulator.txt
38 - DBVDD2-supply, DBVDD3-supply : Additional databus power supplies (wm5102,
39 wm5110, wm8280, wm8998, wm1814)
41 - SPKVDDL-supply, SPKVDDR-supply : Speaker driver power supplies (wm5102,
42 wm5110, wm8280, wm8998, wm1814)
44 - SPKVDD-supply : Speaker driver power supply (wm8997)
46 - DCVDD-supply : Main power supply (cs47l24, wm1831)
48 - MICVDD-supply : Microphone power supply (cs47l24, wm1831)
52 - reset-gpios : GPIO specifier for the GPIO controlling /RESET
54 - clocks: Should reference the clocks supplied on MCLK1 and MCLK2
55 - clock-names: Should contains two strings:
56 "mclk1" for the clock supplied on MCLK1, recommended to be a high
57 quality audio reference clock
58 "mclk2" for the clock supplied on MCLK2, recommended to be an always on
61 - wlf,gpio-defaults : A list of GPIO configuration register values. Defines
62 for the appropriate values can found in <dt-bindings/mfd/arizona.txt>. If
63 absent, no configuration of these registers is performed. If any entry has
64 a value that is out of range for a 16 bit register then the chip default
65 will be used. If present exactly five values must be specified.
67 - DCVDD-supply, MICVDD-supply : Power supplies, only need to be specified if
68 they are being externally supplied. As covered in
69 Documentation/devicetree/bindings/regulator/regulator.txt
70 (wm5102, wm5110, wm8280, wm8997, wm8998, wm1814)
72 Deprecated properties:
