Required properties: - compatible : "realtek,rt5668b" - 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. Pins on the device (for linking into audio routes) for RT5668B: * DMIC L1 * DMIC R1 * IN1P * HPOL * HPOR Example: rt5668 { compatible = "realtek,rt5668b"; reg = <0x1a>; interrupt-parent = <&gpio>; interrupts = <TEGRA_GPIO(U, 6) IRQ_TYPE_LEVEL_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>; }; |
