1 Wolfson Arizona class audio SoCs
3 These devices are audio SoCs with extensive digital capabilites and a range
8 - compatible : One of the following chip-specific strings:
13 - reg : I2C slave address when connected using I2C, chip select number when
16 - interrupts : The interrupt line the /IRQ signal for the device is
18 - interrupt-controller : Arizona class devices contain interrupt controllers
19 and may provide interrupt services to other devices.
20 - interrupt-parent : The parent interrupt controller.
21 - #interrupt-cells: the number of cells to describe an IRQ, this should be 2.
22 The first cell is the IRQ number.
23 The second cell is the flags, encoded as the trigger masks from
24 Documentation/devicetree/bindings/interrupts.txt
26 - gpio-controller : Indicates this device is a GPIO controller.
27 - #gpio-cells : Must be 2. The first cell is the pin number and the
28 second cell is used to specify optional parameters (currently unused).
30 - AVDD-supply, DBVDD1-supply, CPVDD-supply : Power supplies for the device,
31 as covered in Documentation/devicetree/bindings/regulator/regulator.txt
33 - DBVDD2-supply, DBVDD3-supply : Additional databus power supplies (wm5102,
36 - SPKVDDL-supply, SPKVDDR-supply : Speaker driver power supplies (wm5102,
39 - SPKVDD-supply : Speaker driver power supply (wm8997)
43 - wlf,reset : GPIO specifier for the GPIO controlling /RESET
44 - wlf,ldoena : GPIO specifier for the GPIO controlling LDOENA
46 - wlf,gpio-defaults : A list of GPIO configuration register values. Defines
47 for the appropriate values can found in <dt-bindings/mfd/arizona.txt>. If
48 absent, no configuration of these registers is performed. If any entry has
49 a value that is out of range for a 16 bit register then the chip default
50 will be used. If present exactly five values must be specified.
52 - wlf,inmode : A list of INn_MODE register values, where n is the number
53 of input signals. Valid values are 0 (Differential), 1 (Single-ended) and
54 2 (Digital Microphone). If absent, INn_MODE registers set to 0 by default.
55 If present, values must be specified less than or equal to the number of
56 input singals. If values less than the number of input signals, elements
57 that has not been specifed are set to 0 by default.
59 - wlf,dmic-ref : DMIC reference voltage source for each input, can be
60 selected from either MICVDD or one of the MICBIAS's, defines
61 (ARIZONA_DMIC_xxxx) are provided in <dt-bindings/mfd/arizona.txt>. If
62 present, the number of values should be less than or equal to the
63 number of inputs, unspecified inputs will use the chip default.
65 - DCVDD-supply, MICVDD-supply : Power supplies, only need to be specified if
66 they are being externally supplied. As covered in
67 Documentation/devicetree/bindings/regulator/regulator.txt
70 - ldo1 : Initial data for the LDO1 regulator, as covered in
71 Documentation/devicetree/bindings/regulator/regulator.txt
72 - micvdd : Initial data for the MICVDD regulator, as covered in
73 Documentation/devicetree/bindings/regulator/regulator.txt
