The binding states the reset GPIO property shall be named
"cirrus,gpio-nreset" and this is what the driver looks for,
but the example uses "gpio-reset". Fix this here.

CS42L52 audio CODEC
|
|
|
|
Required properties:
|
|
|
|
- compatible : "cirrus,cs42l56"
|
|
|
|
- reg : the I2C address of the device for I2C
|
|
|
|
- VA-supply, VCP-supply, VLDO-supply : power supplies for the device,
|
|
as covered in Documentation/devicetree/bindings/regulator/regulator.txt.
|
|
|
|
Optional properties:
|
|
|
|
- cirrus,gpio-nreset : GPIO controller's phandle and the number
|
|
of the GPIO used to reset the codec.
|
|
|
|
- cirrus,chgfreq-divisor : Values used to set the Charge Pump Frequency.
|
|
Allowable values of 0x00 through 0x0F. These are raw values written to the
|
|
register, not the actual frequency. The frequency is determined by the following.
|
|
Frequency = MCLK / 4 * (N+2)
|
|
N = chgfreq_val
|
|
MCLK = Where MCLK is the frequency of the mclk signal after the MCLKDIV2 circuit.
|
|
|
|
- cirrus,ain1a-ref-cfg, ain1b-ref-cfg : boolean, If present, AIN1A or AIN1B are configured
|
|
as a pseudo-differential input referenced to AIN1REF/AIN3A.
|
|
|
|
- cirrus,ain2a-ref-cfg, ain2b-ref-cfg : boolean, If present, AIN2A or AIN2B are configured
|
|
as a pseudo-differential input referenced to AIN2REF/AIN3B.
|
|
|
|
- cirrus,micbias-lvl: Set the output voltage level on the MICBIAS Pin.
|
|
0 = 0.5 x VA
|
|
1 = 0.6 x VA
|
|
2 = 0.7 x VA
|
|
3 = 0.8 x VA
|
|
4 = 0.83 x VA
|
|
5 = 0.91 x VA
|
|
|
|
- cirrus,adaptive-pwr-cfg : Configures how the power to the Headphone and Lineout
|
|
Amplifiers adapt to the output signal levels.
|
|
0 = Adapt to Volume Mode. Voltage level determined by the sum of the relevant volume settings.
|
|
1 = Fixed - Headphone and Line Amp supply = + or - VCP/2.
|
|
2 = Fixed - Headphone and Line Amp supply = + or - VCP.
|
|
3 = Adapted to Signal; Voltage level is dynamically determined by the output signal.
|
|
|
|
- cirrus,hpf-left-freq, hpf-right-freq : Sets the corner frequency (-3dB point) for the internal High-Pass
|
|
Filter.
|
|
0 = 1.8Hz
|
|
1 = 119Hz
|
|
2 = 236Hz
|
|
3 = 464Hz
|
|
|
|
|
|
Example:
|
|
|
|
codec: codec@4b {
|
|
compatible = "cirrus,cs42l56";
|
|
reg = <0x4b>;
|
|
cirrus,gpio-nreset = <&gpio 10 0>;
|
|
cirrus,chgfreq-divisor = <0x05>;
|
|
cirrus.ain1_ref_cfg;
|
|
cirrus,micbias-lvl = <5>;
|
|
VA-supply = <®_audio>;
|
|
};
