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
Pins on the device (for linking into audio routes) for RT5645/RT5650:
* DMIC L1
* DMIC R1
* DMIC L2
* DMIC R2
* IN1P
* IN1N
* IN2P
* IN2N
* Haptic Generator
* HPOL
* HPOR
* LOUTL
* LOUTR
* PDM1L
* PDM1R
* SPOL
* SPOR
Example:
codec: rt5650@1a {
compatible = "realtek,rt5650";
reg = <0x1a>;
hp-detect-gpios = <&gpio 19 0>;
interrupt-parent = <&gpio>;
interrupts = <7 IRQ_TYPE_EDGE_FALLING>;
realtek,dmic-en = "true";
realtek,en-jd-func = "true";
realtek,jd-mode = <3>;
};
