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. - #clock-cells : Should be set to '<1>', wclk and bclk sources provided. - clock-output-names : Name given for DAI clocks output. - clocks : phandle and clock specifier for codec MCLK. - clock-names : Clock name string for 'clocks' attribute, should be "mclk". - realtek,dmic-clk-rate-hz : Set the clock rate (hz) for the requirement of the particular DMIC. - realtek,dmic-delay-ms : Set the delay time (ms) for the requirement of the particular DMIC. - realtek,dmic-clk-driving-high : Set the high driving of the DMIC clock out.
