13 - compatible : One of the following chip-specific strings:
24 - reg : I2C slave address when connected using I2C, chip select number when
27 - DCVDD-supply : Power supply for the device as defined in
28 bindings/regulator/regulator.txt
29 Mandatory on CS47L15, CS47L35, CS47L90, CS47L91, CS42L92, CS47L92, CS47L93
30 Optional on CS47L85, WM1840
32 - AVDD-supply, DBVDD1-supply, DBVDD2-supply, CPVDD1-supply, CPVDD2-supply :
33 Power supplies for the device
35 - DBVDD3-supply, DBVDD4-supply : Power supplies for the device
36 (CS47L85, CS47L90, CS47L91, WM1840)
38 - SPKVDDL-supply, SPKVDDR-supply : Power supplies for the device
41 - SPKVDD-supply : Power supply for the device
44 - interrupt-controller : Indicates that this device is an interrupt controller
46 - #interrupt-cells: the number of cells to describe an IRQ, must be 2.
47 The first cell is the IRQ number.
48 The second cell is the flags, encoded as the trigger masks from
49 bindings/interrupt-controller/interrupts.txt
51 - gpio-controller : Indicates this device is a GPIO controller.
53 - #gpio-cells : Must be 2. The first cell is the pin number. The second cell
54 is reserved for future use and must be zero
56 - interrupt-parent : The parent interrupt controller.
58 - interrupts : The interrupt line the /IRQ signal for the device is
63 - MICVDD-supply : Power supply, only need to be specified if
66 - reset-gpios : One entry specifying the GPIO controlling /RESET.
67 As defined in bindings/gpio.txt.
68 Although optional, it is strongly recommended to use a hardware reset
70 - clocks: Should reference the clocks supplied on MCLK1, MCLK2 and MCLK3
71 - clock-names: May contain up to three strings:
72 "mclk1" for the clock supplied on MCLK1, recommended to be a high
73 quality audio reference clock
74 "mclk2" for the clock supplied on MCLK2, required to be an always on
76 "mclk3" for the clock supplied on MCLK3
78 - MICBIASx : Initial data for the MICBIAS regulators, as covered in
79 Documentation/devicetree/bindings/regulator/regulator.txt.
80 One for each MICBIAS generator (MICBIAS1, MICBIAS2, ...)
83 One for each output pin (MICBIAS1A, MIBCIAS1B, MICBIAS2A, ...)
84 (all except CS47L85, WM1840)
86 The following following additional property is supported for the generator
88 - cirrus,ext-cap : Set to 1 if the MICBIAS has external decoupling
92 micvdd : Node containing initialization data for the micvdd regulator
93 See bindings/regulator/arizona-regulator.txt
95 ldo1 : Node containing initialization data for the LDO1 regulator
96 See bindings/regulator/arizona-regulator.txt
