Kernel-4.18.0-80.el8_rt5645

RT5650/RT5645 audio CODEC

This device supports I2C only.

Required properties:

• compatible : One of “realtek,rt5645” or “realtek,rt5650”.

• reg : The I2C address of the device.

• interrupts : The CODEC’s interrupt output.

Optional properties:

• hp-detect-gpios:
  a GPIO spec for the external headphone detect pin. If jd-mode = 0,
  we will get the JD status by getting the value of hp-detect-gpios.

• realtek,in2-differential
  Boolean. Indicate MIC2 input are differential, rather than single-ended.

• realtek,dmic1-data-pin
  0: dmic1 is not used
  1: using IN2P pin as dmic1 data pin
  2: using GPIO6 pin as dmic1 data pin
  3: using GPIO10 pin as dmic1 data pin
  4: using GPIO12 pin as dmic1 data pin

• realtek,dmic2-data-pin
  0: dmic2 is not used
  1: using IN2N pin as dmic2 data pin
  2: using GPIO5 pin as dmic2 data pin
  3: using GPIO11 pin as dmic2 data pin

– realtek,jd-mode : The JD mode of rt5645/rt5650
0 : rt5645/rt5650 JD function is not used
1 : Mode-0 (VDD=3.3V), two port jack detection
2 : Mode-1 (VDD=3.3V), one port jack detection
3 : Mode-2 (VDD=1.8V), one port jack detection
