e7a0332f71 ASoC: ts3a227e: fix sparse warning 
this patch fixes following sparse warning:
ts3a227e.c:222:5: warning: symbol 'ts3a227e_enable_jack_detect' was not declared. Should it be static?

ddf9ea21f5 ASoC: ts3a227e: Remap keys to match Android headset specification 
ts3a227e datasheet says typical key resistance is
  key1 50 Ohm
  key2 135 Ohm
  key3 240 Ohm
  key4 470 Ohm

The android headset specification expect buttons impedance:
  A (MEDIA) 0-70 Ohm
  D (VOICECOMMAND) 110-180 Ohm
  B (VOLUMEUP) 210-290 Ohm
  C (VOLUMEDOWN) 360-680 Ohm

Thus key mapping should be
  key1 - MEDIA
  key2 - VOICECOMMAND
  key3 - VOLUMEUP
  key3 - VOLUMEDOWN

8e3e36e87c ASoC: ts3a227e: Check and report jack status at probe 
ts3a227e does not trigger interrupt to report jack status when system
boots from warm reset because ts3a227e's power remains on during warm reset.
Read jack status at probe to get current jack status.
Note that if system boots from EC reset, then this issue will not
happen.

2880fc8779 ASoC: add TI ts3a227e headset chip driver 
The TS3A227E is an autonomous audio accessory detection and
configuration switch that detects 3-pole or 4-pole audio accessories
and configures internal switches to route the signals accordingly.

This chip also has built-in support for the new button standard
described in the Android "Wired audio headset specification" v1.0.
These buttons will be reported on the jack as buttons 0-3 mapped to
KEY_MEDIA, KEY_VOLUMEUP, KEY_VOLUMEDOWN, and KEY_VOICE_COMMAND.

This will be added as an aux_dev and have the jack passed in from the
machine driver.
