The Android 3.5mm Headset jack specification mentions that BTN_0 should
be mapped to KEY_MEDIA, but this is less logical than KEY_PLAYPAUSE,
which has much broader userspace support.
For example, the Chrome OS userspace now supports KEY_PLAYPAUSE to toggle
play/pause of videos and audio, but does not handle KEY_MEDIA.
Furthermore, Android itself now supports KEY_PLAYPAUSE equivalently, as the
new USB headset spec requires KEY_PLAYPAUSE for BTN_0.

This patch adds the acpi match table for the ts3a227e audio accessory
detection device. This enables headset features like jack plug/unplug
notifications, mic presence, and button pressed events.

After suspend -> resume the ts3a227e_interrupt sometimes comes before i2c
controller resume is called .regmap_read will return incorrect status
and report a wrong jack status.This patch will disable irq on suspend
and enable irq again on the resume to make sure interrupt is coming
after TI resumes. Also We should return if there is read err,the
interrupt will come again since it is level triggered and we are not yet
clear the interrupt.
In addtion,cht_bsw_max98090_ti machine driver registered additional
notifier base on jack event which will program the audio codec.there
will be codec timeout err if such event occurs prior to i2c controller
is resumed.

this patch fixes following sparse warning:

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.

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.
