Merge remote-tracking branches 'asoc/topic/cs43130', 'asoc/topic/cs53l30',...

Merge remote-tracking branches 'asoc/topic/cs43130', 'asoc/topic/cs53l30', 'asoc/topic/cygnus' and 'asoc/topic/davinci' into asoc-next
CS43130 DAC
Required properties:
- compatible : "cirrus,cs43130", "cirrus,cs4399", "cirrus,cs43131",
"cirrus,cs43198"
- reg : the I2C address of the device for I2C
- VA-supply, VP-supply, VL-supply, VCP-supply, VD-supply:
power supplies for the device, as covered in
Documentation/devicetree/bindings/regulator/regulator.txt.
Optional properties:
- reset-gpios : Active low GPIO used to reset the device
- cirrus,xtal-ibias:
When external MCLK is generated by external crystal
oscillator, CS43130 can be used to provide bias current
for external crystal. Amount of bias current sent is
set as:
1 = 7.5uA
2 = 12.5uA
3 = 15uA
- cirrus,dc-measure:
Boolean, define to enable headphone DC impedance measurement.
- cirrus,ac-measure:
Boolean, define to enable headphone AC impedance measurement.
DC impedance must also be enabled for AC impedance measurement.
- cirrus,dc-threshold:
Define 2 DC impedance thresholds in ohms for HP output control.
Default values are 50 and 120 Ohms.
- cirrus,ac-freq:
Define the frequencies at which to measure HP AC impedance.
Only used if "cirrus,dc-measure" is defined.
Exactly 10 frequencies must be defined.
If this properties is undefined, by default,
following frequencies are used:
<24 43 93 200 431 928 2000 4309 9283 20000>
The above frequencies are logarithmically equally spaced.
Log base is 10.
Example:
cs43130: audio-codec@30 {
compatible = "cirrus,cs43130";
reg = <0x30>;
reset-gpios = <&axi_gpio 54 0>;
VA-supply = <&dummy_vreg>;
VP-supply = <&dummy_vreg>;
VL-supply = <&dummy_vreg>;
VCP-supply = <&dummy_vreg>;
VD-supply = <&dummy_vreg>;
cirrus,xtal-ibias = <2>;
interrupt-parent = <&gpio0>;
interrupts = <55 8>;
cirrus,dc-measure;
cirrus,ac-measure;
cirrus,dc-threshold = /bits/ 16 <20 100>;
cirrus,ac-freq = /bits/ 16 <24 43 93 200 431 928 2000 4309 9283 20000>;
