Merge tag 'asoc-v3.19' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus
ASoC: Updates for v3.19 Lots and lots of changes this time around, the usual set of driver updates and a huge bulk of cleanups from Lars-Peter. Probably the most interesting thing for most users is the Intel driver updates which will (with some more machine integration work) enable support for newer x86 laptops. - Conversion of AC'97 drivers to use regmap, bringing us closer to the removal of the ASoC level I/O code. - Clean up a lot of old drivers that were open coding things that have subsequently been implemented in the core. - Some DAPM performance improvements. - Removal of the now seldom used CODEC mutex. - Lots of updates for the newer Intel SoC support, including support for the DSP and some Cherrytrail and Braswell machine drivers. - Support for Samsung boards using rt5631 as the CODEC. - Removal of the obsolete AFEB9260 machine driver. - Driver support for the TI TS3A227E headset driver used in some Chrombeooks.

+Texas Instruments TS3A227E
+Autonomous Audio Accessory Detection and Configuration Switch
+
+The TS3A227E detect headsets of 3-ring and 4-ring standards and
+switches automatically to route the microphone correctly. It also
+handles key press detection in accordance with the Android audio
+headset specification v1.0.
+
+Required properties:
+
+ - compatible: Should contain "ti,ts3a227e".
+ - reg: The i2c address. Should contain <0x3b>.
+ - interrupt-parent: The parent interrupt controller
+ - interrupts: Interrupt number for /INT pin from the 227e
+
+
+Examples:
+
+ i2c {
+ ts3a227e@3b {
+ compatible = "ti,ts3a227e";
+ reg = <0x3b>;
+ interrupt-parent = <&gpio>;
+ interrupts = <3 IRQ_TYPE_LEVEL_LOW>;
+ };
+ };
