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:
12 - reg : I2C slave address when connected using I2C, chip select number when
15 - interrupts : The interrupt line the /IRQ signal for the device is
17 - interrupt-controller : Arizona class devices contain interrupt controllers
18 and may provide interrupt services to other devices.
19 - interrupt-parent : The parent interrupt controller.
20 - #interrupt-cells: the number of cells to describe an IRQ, this should be 2.
21 The first cell is the IRQ number.
22 The second cell is the flags, encoded as the trigger masks from
23 Documentation/devicetree/bindings/interrupts.txt
25 - gpio-controller : Indicates this device is a GPIO controller.
26 - #gpio-cells : Must be 2. The first cell is the pin number and the
27 second cell is used to specify optional parameters (currently unused).
29 - AVDD-supply, DBVDD1-supply, DBVDD2-supply, DBVDD3-supply (wm5102, wm5110),
30 CPVDD-supply, SPKVDDL-supply (wm5102, wm5110), SPKVDDR-supply (wm5102,
31 wm5110), SPKVDD-supply (wm8997) : Power supplies for the device, as covered
32 in Documentation/devicetree/bindings/regulator/regulator.txt
36 - wlf,reset : GPIO specifier for the GPIO controlling /RESET
37 - wlf,ldoena : GPIO specifier for the GPIO controlling LDOENA
39 - wlf,gpio-defaults : A list of GPIO configuration register values. If
40 absent, no configuration of these registers is performed. If any
41 entry has a value that is out of range for a 16 bit register then
42 the chip default will be used. If present exactly five values must
45 - wlf,inmode : A list of INn_MODE register values, where n is the number
46 of input signals. Valid values are 0 (Differential), 1 (Single-ended) and
47 2 (Digital Microphone). If absent, INn_MODE registers set to 0 by default.
48 If present, values must be specified less than or equal to the number of
49 input singals. If values less than the number of input signals, elements
50 that has not been specifed are set to 0 by default.
52 - DCVDD-supply, MICVDD-supply : Power supplies, only need to be specified if
53 they are being externally supplied. As covered in
54 Documentation/devicetree/bindings/regulator/regulator.txt
57 - ldo1 : Initial data for the LDO1 regulator, as covered in
58 Documentation/devicetree/bindings/regulator/regulator.txt
59 - micvdd : Initial data for the MICVDD regulator, as covered in
60 Documentation/devicetree/bindings/regulator/regulator.txt
