The patch

ASoC: cs43130: Add devicetree bindings for CS43130

has been applied to the asoc tree at

git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark

+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>;
