+RT5659/RT5658 audio CODEC
+
+This device supports I2C only.
+
+Required properties:
+
+- compatible : One of "realtek,rt5659" or "realtek,rt5658".
+
+- reg : The I2C address of the device.
+
+- interrupts : The CODEC's interrupt output.
+
+Optional properties:
+
+- realtek,in1-differential
+- realtek,in3-differential
+- realtek,in4-differential
+  Boolean. Indicate MIC1/3/4 input are differential, rather than single-ended.
+
+- realtek,dmic1-data-pin
+  0: dmic1 is not used
+  1: using IN2N pin as dmic1 data pin
+  2: using GPIO5 pin as dmic1 data pin
+  3: using GPIO9 pin as dmic1 data pin
+  4: using GPIO11 pin as dmic1 data pin
+
+- realtek,dmic2-data-pin
+  0: dmic2 is not used
+  1: using IN2P pin as dmic2 data pin
+  2: using GPIO6 pin as dmic2 data pin
+  3: using GPIO10 pin as dmic2 data pin
+  4: using GPIO12 pin as dmic2 data pin
+
+- realtek,jd-src
+  0: No JD is used
+  1: using JD3 as JD source
+
+- realtek,ldo1-en-gpios : The GPIO that controls the CODEC's LDO1_EN pin.
+- realtek,reset-gpios : The GPIO that controls the CODEC's RESET pin.
