| 2 | |
| 3 | Required properties: |
| 4 | |
| 5 | - compatible : "cirrus,cs35l32" |
| 6 | |
| 7 | - reg : the I2C address of the device for I2C. Address is determined by the level |
| 8 | of the AD0 pin. Level 0 is 0x40 while Level 1 is 0x41. |
| 9 | |
| 10 | - VA-supply, VP-supply : power supplies for the device, |
| 11 | as covered in Documentation/devicetree/bindings/regulator/regulator.txt. |
| 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 | - cirrus,boost-manager : Boost voltage control. |
| 19 | 0 = Automatically managed. Boost-converter output voltage is the higher |
| 20 | of the two: Class G or adaptive LED voltage. |
| 21 | 1 = Automatically managed irrespective of audio, adapting for low-power |
| 22 | dissipation when LEDs are ON, and operating in Fixed-Boost Bypass Mode |
| 23 | if LEDs are OFF (VBST = VP). |
| 24 | 2 = (Default) Boost voltage fixed in Bypass Mode (VBST = VP). |
| 25 | 3 = Boost voltage fixed at 5 V. |
| 26 | |
| 27 | - cirrus,sdout-datacfg : Data configuration for dual CS35L32 applications only. |
| 28 | Determines the data packed in a two-CS35L32 configuration. |
| 29 | 0 = Left/right channels VMON[11:0], IMON[11:0], VPMON[7:0]. |
| 30 | 1 = Left/right channels VMON[11:0], IMON[11:0], STATUS. |
| 31 | 2 = (Default) left/right channels VMON[15:0], IMON [15:0]. |
| 32 | 3 = Left/right channels VPMON[7:0], STATUS. |
| 33 | |
| 34 | - cirrus,sdout-share : SDOUT sharing. Determines whether one or two CS35L32 |
| 35 | devices are on board sharing SDOUT. |
| 36 | 0 = (Default) One IC. |
| 37 | 1 = Two IC's. |
| 38 | |
| 39 | - cirrus,battery-recovery : Low battery nominal recovery threshold, rising VP. |
| 40 | 0 = 3.1V |
| 41 | 1 = 3.2V |
| 42 | 2 = 3.3V (Default) |
| 43 | 3 = 3.4V |
| 44 | |
| 45 | - cirrus,battery-threshold : Low battery nominal threshold, falling VP. |
| 46 | 0 = 3.1V |
| 47 | 1 = 3.2V |
| 48 | 2 = 3.3V |
| 49 | 3 = 3.4V (Default) |
| 50 | 4 = 3.5V |
| 51 | 5 = 3.6V |
| 52 | |
| 53 | Example: |
| 54 | |
| 55 | codec: codec@40 { |
| 56 | compatible = "cirrus,cs35l32"; |
| 57 | reg = <0x40>; |
| 58 | reset-gpios = <&gpio 10 0>; |
| 59 | cirrus,boost-manager = <0x03>; |
| 60 | cirrus,sdout-datacfg = <0x02>; |
| 61 | VA-supply = <®_audio>; |
| 62 | }; |
