| RT5682 audio CODEC |
| |
| This device supports I2C only. |
| |
| Required properties: |
| |
| - compatible : "realtek,rt5682" or "realtek,rt5682i" |
| |
| - reg : The I2C address of the device. |
| |
| Optional properties: |
| |
| - interrupts : The CODEC's interrupt output. |
| |
| - realtek,dmic1-data-pin |
| 0: dmic1 is not used |
| 1: using GPIO2 pin as dmic1 data pin |
| 2: using GPIO5 pin as dmic1 data pin |
| |
| - realtek,dmic1-clk-pin |
| 0: using GPIO1 pin as dmic1 clock pin |
| 1: using GPIO3 pin as dmic1 clock pin |
| |
| - realtek,jd-src |
| 0: No JD is used |
| 1: using JD1 as JD source |
| |
| - realtek,ldo1-en-gpios : The GPIO that controls the CODEC's LDO1_EN pin. |
| |
| - realtek,btndet-delay |
| The debounce delay for push button. |
| The delay time is realtek,btndet-delay value multiple of 8.192 ms. |
| If absent, the default is 16. |
| |

| Example: |
| |
| rt5682 { |
| compatible = "realtek,rt5682i"; |
| reg = <0x1a>; |
| interrupt-parent = <&gpio>; |
| interrupts = <TEGRA_GPIO(U, 6) GPIO_ACTIVE_HIGH>; |
| realtek,ldo1-en-gpios = |
| <&gpio TEGRA_GPIO(R, 2) GPIO_ACTIVE_HIGH>; |
| realtek,dmic1-data-pin = <1>; |
| realtek,dmic1-clk-pin = <1>; |
| realtek,jd-src = <1>; |
| realtek,btndet-delay = <16>; |
| }; |
