+RT5668B audio CODEC
+This device supports I2C only.
+- compatible : "realtek,rt5668b"
+- reg : The I2C address of the device.
+- interrupts : The CODEC's interrupt output.
+ 0: dmic1 is not used
+ 1: using GPIO2 pin as dmic1 data pin
+ 2: using GPIO5 pin as dmic1 data pin
+ 0: using GPIO1 pin as dmic1 clock pin
+ 1: using GPIO3 pin as dmic1 clock pin
+ 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.
