1 | CS4265 audio CODEC | ||
2 | |||
3 | This device supports I2C only. | ||
4 | |||
5 | Required properties: | ||
6 | |||
7 | - compatible : "cirrus,cs4265" | ||
8 | |||
9 | - reg : the I2C address of the device for I2C. The I2C address depends on | ||
10 | the state of the AD0 pin. If AD0 is high, the i2c address is 0x4f. | ||
11 | If it is low, the i2c address is 0x4e. | ||
12 | |||
13 | Optional properties: | ||
14 | |||
15 | - reset-gpios : a GPIO spec for the reset pin. If specified, it will be | ||
16 | deasserted before communication to the codec starts. | ||
17 | |||
18 | Examples: | ||
19 | |||
20 | codec_ad0_high: cs4265@4f { /* AD0 Pin is high */ | ||
21 | compatible = "cirrus,cs4265"; | ||
22 | reg = <0x4f>; | ||
23 | }; | ||
24 | |||
25 | |||
26 | codec_ad0_low: cs4265@4e { /* AD0 Pin is low */ | ||
27 | compatible = "cirrus,cs4265"; | ||
28 | reg = <0x4e>; | ||
29 | }; | ||
