1 Analog Devices ADAU1701
2
3 Required properties:
4
5 - compatible: Should contain "adi,adau1701"
6 - reg: The i2c address. Value depends on the state of ADDR0
7 and ADDR1, as wired in hardware.
8
9 Optional properties:
10
11 - reset-gpio: A GPIO spec to define which pin is connected to the
12 chip's !RESET pin. If specified, the driver will
13 assert a hardware reset at probe time.
14 - adi,pll-mode-gpios: An array of two GPIO specs to describe the GPIOs
15 the ADAU's PLL config pins are connected to.
16 The state of the pins are set according to the
17 configured clock divider on ASoC side before the
18 firmware is loaded.
19 - adi,pin-config: An array of 12 numerical values selecting one of the
20 pin configurations as described in the datasheet,
21 table 53. Note that the value of this property has
22 to be prefixed with '/bits/ 8'.
23 - avdd-supply: Power supply for AVDD, providing 3.3V
24 - dvdd-supply: Power supply for DVDD, providing 3.3V
