13 - compatible : One of the following chip-specific strings:
20 - reg : I2C slave address when connected using I2C, chip select number when
23 - DCVDD-supply : Power supply for the device as defined in
24 bindings/regulator/regulator.txt
25 Mandatory on CS47L35, CS47L90, CS47L91
26 Optional on CS47L85, WM1840
28 - AVDD-supply, DBVDD1-supply, DBVDD2-supply, CPVDD1-supply, CPVDD2-supply :
29 Power supplies for the device
31 - DBVDD3-supply, DBVDD4-supply : Power supplies for the device
32 (CS47L85, CS47L90, CS47L91, WM1840)
34 - SPKVDDL-supply, SPKVDDR-supply : Power supplies for the device
37 - SPKVDD-supply : Power supply for the device
40 - interrupt-controller : Indicates that this device is an interrupt controller
42 - #interrupt-cells: the number of cells to describe an IRQ, must be 2.
43 The first cell is the IRQ number.
44 The second cell is the flags, encoded as the trigger masks from
45 bindings/interrupt-controller/interrupts.txt
47 - gpio-controller : Indicates this device is a GPIO controller.
49 - #gpio-cells : Must be 2. The first cell is the pin number. The second cell
50 is reserved for future use and must be zero
52 - interrupt-parent : The parent interrupt controller.
54 - interrupts : The interrupt line the /IRQ signal for the device is
59 - MICVDD-supply : Power supply, only need to be specified if
62 - reset-gpios : One entry specifying the GPIO controlling /RESET.
63 As defined in bindings/gpio.txt.
64 Although optional, it is strongly recommended to use a hardware reset
66 - MICBIASx : Initial data for the MICBIAS regulators, as covered in
67 Documentation/devicetree/bindings/regulator/regulator.txt.
68 One for each MICBIAS generator (MICBIAS1, MICBIAS2, ...)
71 One for each output pin (MICBIAS1A, MIBCIAS1B, MICBIAS2A, ...)
72 (all except CS47L85, WM1840)
74 The following following additional property is supported for the generator
76 - cirrus,ext-cap : Set to 1 if the MICBIAS has external decoupling
80 micvdd : Node containing initialization data for the micvdd regulator
81 See bindings/regulator/arizona-regulator.txt
83 ldo1 : Node containing initialization data for the LDO1 regulator
84 See bindings/regulator/arizona-regulator.txt
