-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.
-
-- avdd-supply: Power supply for AVDD, providing 1.8V.
-
-- cpvdd-supply: Power supply for CPVDD, providing 3.5V.
-
-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.
-
-- cbj-sleeve-gpios:
-  a GPIO spec to control the external combo jack circuit to tie the sleeve/ring2
-  contacts to the ground or floating. It could avoid some electric noise from the
-  active speaker jacks.
-
-- 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
-
