| 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 | - AVDD-supply: phandle to the regulator supplying analog power through the |
| 12 | AVDD pin |
| 13 | |
| 14 | - MICVDD-supply: phandle to the regulator supplying power for the microphone |
| 15 | bias through the MICVDD pin. Either MICVDD or VBAT should be present. |
| 16 | |
| 17 | - VBAT-supply: phandle to the regulator supplying battery power through the |
| 18 | VBAT pin. Either MICVDD or VBAT should be present. |
| 19 | |
| 20 | - DBVDD-supply: phandle to the regulator supplying I/O power through the DBVDD |
| 21 | pin. |
| 22 | |
| 23 | - LDO1-IN-supply: phandle to the regulator supplying power to the digital core |
| 24 | and charge pump through the LDO1_IN pin. |
| 25 | |
| 26 | Optional properties: |
| 27 | |
| 28 | - interrupts : The CODEC's interrupt output. |
| 29 | |
| 30 | - realtek,dmic1-data-pin |
| 31 | 0: dmic1 is not used |
| 32 | 1: using GPIO2 pin as dmic1 data pin |
| 33 | 2: using GPIO5 pin as dmic1 data pin |
| 34 | |
| 35 | - realtek,dmic1-clk-pin |
| 36 | 0: using GPIO1 pin as dmic1 clock pin |
| 37 | 1: using GPIO3 pin as dmic1 clock pin |
| 38 | |
| 39 | - realtek,jd-src |
| 40 | 0: No JD is used |
| 41 | 1: using JD1 as JD source |
| 42 | |
| 43 | - realtek,ldo1-en-gpios : The GPIO that controls the CODEC's LDO1_EN pin. |
| 44 | |
| 45 | - realtek,btndet-delay |
| 46 | The debounce delay for push button. |
| 47 | The delay time is realtek,btndet-delay value multiple of 8.192 ms. |
| 48 | If absent, the default is 16. |
| 49 | |
| 50 | - #clock-cells : Should be set to '<1>', wclk and bclk sources provided. |
| 51 | - clock-output-names : Name given for DAI clocks output. |
| 52 | |
| 53 | - clocks : phandle and clock specifier for codec MCLK. |
| 54 | - clock-names : Clock name string for 'clocks' attribute, should be "mclk". |
| 55 | |
| 56 | - realtek,dmic-clk-rate-hz : Set the clock rate (hz) for the requirement of |
| 57 | the particular DMIC. |
| 58 | |
| 59 | - realtek,dmic-delay-ms : Set the delay time (ms) for the requirement of |
| 60 | the particular DMIC. |
| 61 | |
| 62 | - realtek,dmic-clk-driving-high : Set the high driving of the DMIC clock out. |
| 63 | |
| 64 | - #sound-dai-cells: Should be set to '<1>'. |
| 65 | |
