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-parent : The parent interrupt controller.
26 - #interrupt-cells: the number of cells to describe an IRQ, this should be 2.
27 The first cell is the IRQ number.
28 The second cell is the flags, encoded as the trigger masks from
29 Documentation/devicetree/bindings/interrupt-controller/interrupts.txt
31 - gpio-controller : Indicates this device is a GPIO controller.
32 - #gpio-cells : Must be 2. The first cell is the pin number and the
33 second cell is used to specify optional parameters, see ../gpio/gpio.txt
36 - AVDD-supply, DBVDD1-supply, CPVDD-supply : Power supplies for the device,
37 as covered in Documentation/devicetree/bindings/regulator/regulator.txt
39 - DBVDD2-supply, DBVDD3-supply : Additional databus power supplies (wm5102,
40 wm5110, wm8280, wm8998, wm1814)
42 - SPKVDDL-supply, SPKVDDR-supply : Speaker driver power supplies (wm5102,
43 wm5110, wm8280, wm8998, wm1814)
45 - SPKVDD-supply : Speaker driver power supply (wm8997)
47 - DCVDD-supply : Main power supply (cs47l24, wm1831)
49 - MICVDD-supply : Microphone power supply (cs47l24, wm1831)
53 - wlf,reset : GPIO specifier for the GPIO controlling /RESET
55 - clocks: Should reference the clocks supplied on MCLK1 and MCLK2
56 - clock-names: Should contains two strings:
57 "mclk1" for the clock supplied on MCLK1, recommended to be a high
58 quality audio reference clock
59 "mclk2" for the clock supplied on MCLK2, recommended to be an always on
62 - wlf,gpio-defaults : A list of GPIO configuration register values. Defines
63 for the appropriate values can found in <dt-bindings/mfd/arizona.txt>. If
64 absent, no configuration of these registers is performed. If any entry has
65 a value that is out of range for a 16 bit register then the chip default
66 will be used. If present exactly five values must be specified.
68 - wlf,inmode : A list of INn_MODE register values, where n is the number
69 of input signals. Valid values are 0 (Differential), 1 (Single-ended) and
70 2 (Digital Microphone). If absent, INn_MODE registers set to 0 by default.
71 If present, values must be specified less than or equal to the number of
72 input signals. If values less than the number of input signals, elements
73 that have not been specified are set to 0 by default. Entries are:
74 <IN1, IN2, IN3, IN4> (wm5102, wm5110, wm8280, wm8997)
75 <IN1A, IN2A, IN1B, IN2B> (wm8998, wm1814)
76 - wlf,out-mono : A list of boolean values indicating whether each output is
77 mono or stereo. Position within the list indicates the output affected
78 (eg. First entry in the list corresponds to output 1). A non-zero value
79 indicates a mono output. If present, the number of values should be less
80 than or equal to the number of outputs, if less values are supplied the
81 additional outputs will be treated as stereo.
83 - wlf,dmic-ref : DMIC reference voltage source for each input, can be
84 selected from either MICVDD or one of the MICBIAS's, defines
85 (ARIZONA_DMIC_xxxx) are provided in <dt-bindings/mfd/arizona.txt>. If
86 present, the number of values should be less than or equal to the
87 number of inputs, unspecified inputs will use the chip default.
89 - wlf,max-channels-clocked : The maximum number of channels to be clocked on
90 each AIF, useful for I2S systems with multiple data lines being mastered.
91 Specify one cell for each AIF to be configured, specify zero for AIFs that
92 should be handled normally.
93 If present, number of cells must be less than or equal to the number of
94 AIFs. If less than the number of AIFs, for cells that have not been
95 specified the corresponding AIFs will be treated as default setting.
97 - wlf,spk-fmt : PDM speaker data format, must contain 2 cells (OUT5 and OUT6).
98 See the datasheet for values.
99 The second cell is ignored for codecs that do not have OUT6 (wm5102, wm8997,
102 - wlf,spk-mute : PDM speaker mute setting, must contain 2 cells (OUT5 and OUT6).
103 See the datasheet for values.
104 The second cell is ignored for codecs that do not have OUT6 (wm5102, wm8997,
107 - DCVDD-supply, MICVDD-supply : Power supplies, only need to be specified if
108 they are being externally supplied. As covered in
109 Documentation/devicetree/bindings/regulator/regulator.txt
