-RT5640/RT5639 audio CODEC
-
-This device supports I2C only.
-
-Required properties:
-
-- compatible : One of "realtek,rt5640" or "realtek,rt5639".
-
-- reg : The I2C address of the device.
-
-- interrupts : The CODEC's interrupt output.
-
-Optional properties:
-
-- clocks: The phandle of the master clock to the CODEC
-- clock-names: Should be "mclk"
-
-- realtek,in1-differential
-- realtek,in2-differential
-- realtek,in3-differential
- Boolean. Indicate MIC1/2/3 input are differential, rather than single-ended.
-
-- realtek,lout-differential
- Boolean. Indicate LOUT output is differential, rather than stereo.
-
-- realtek,ldo1-en-gpios : The GPIO that controls the CODEC's LDO1_EN pin.
-
-- realtek,dmic1-data-pin
- 0: dmic1 is not used
- 1: using IN1P pin as dmic1 data pin
- 2: using GPIO3 pin as dmic1 data pin
-
-- realtek,dmic2-data-pin
- 0: dmic2 is not used
- 1: using IN1N pin as dmic2 data pin
- 2: using GPIO4 pin as dmic2 data pin
-
-- realtek,jack-detect-source
- u32. Valid values:
- 0: jack-detect is not used

- 3: Use JD2_IN4N for jack-detect
- 4: Use GPIO2 for jack-detect
- 5: Use GPIO3 for jack-detect
- 6: Use GPIO4 for jack-detect
-
-- realtek,jack-detect-not-inverted
- bool. Normal jack-detect switches give an inverted signal, set this bool
- in the rare case you've a jack-detect switch which is not inverted.
-
-- realtek,over-current-threshold-microamp
- u32, micbias over-current detection threshold in µA, valid values are
- 600, 1500 and 2000µA.
-
