1 | RT5682 audio CODEC |
| 2 | ||
| 3 | This device supports I2C only. | |
| 4 | ||
| 5 | Required properties: | |
| 6 | ||
| 7 | - compatible : "realtek,rt5682" or "realtek,rt5682i" | |
| 8 | ||
| 9 | - reg : The I2C address of the device. | |
| 10 | ||
| 11 | Optional properties: | |
| 12 | ||
| 13 | - interrupts : The CODEC's interrupt output. | |
| 14 | ||
| 15 | - realtek,dmic1-data-pin | |
| 16 | 0: dmic1 is not used | |
| 17 | 1: using GPIO2 pin as dmic1 data pin | |
| 18 | 2: using GPIO5 pin as dmic1 data pin | |
| 19 | ||
| 20 | - realtek,dmic1-clk-pin | |
| 21 | 0: using GPIO1 pin as dmic1 clock pin | |
| 22 | 1: using GPIO3 pin as dmic1 clock pin | |
| 23 | ||
| 24 | - realtek,jd-src | |
| 25 | 0: No JD is used | |
| 26 | 1: using JD1 as JD source | |
| 27 | ||
| 28 | - realtek,ldo1-en-gpios : The GPIO that controls the CODEC's LDO1_EN pin. | |
| 29 | ||
| 059c67f1 SF |
30 | - realtek,btndet-delay |
| 31 | The debounce delay for push button. | |
| 32 | The delay time is realtek,btndet-delay value multiple of 8.192 ms. | |
| 33 | If absent, the default is 16. | |
| 34 | ||

35 | Pins on the device (for linking into audio routes) for RT5682: |
| 36 | ||
| 37 | * DMIC L1 | |
| 38 | * DMIC R1 | |
| 39 | * IN1P | |
| 40 | * HPOL | |
| 41 | * HPOR | |
| 42 | ||
| 43 | Example: | |
| 44 | ||
| 45 | rt5682 { | |
| 46 | compatible = "realtek,rt5682i"; | |
| 47 | reg = <0x1a>; | |
| 48 | interrupt-parent = <&gpio>; | |
| 49 | interrupts = <TEGRA_GPIO(U, 6) GPIO_ACTIVE_HIGH>; | |
| 50 | realtek,ldo1-en-gpios = | |
| 51 | <&gpio TEGRA_GPIO(R, 2) GPIO_ACTIVE_HIGH>; | |
| 52 | realtek,dmic1-data-pin = <1>; | |
| 53 | realtek,dmic1-clk-pin = <1>; | |
| 54 | realtek,jd-src = <1>; | |
| 059c67f1 | 55 | realtek,btndet-delay = <16>; |
| 0ddce71c | 56 | }; |
