2015-07-15ASoC: drivers: Drop owner assignment from i2c_driverKrzysztof Kozlowski1-1/+0
i2c_driver does not need to set an owner because i2c_register_driver() will set it. Signed-off-by: Krzysztof Kozlowski <k.kozlowski@samsung.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2015-07-08ASoC: ts3a227e: do not report jack status when there is i2c read errFang, Yang A1-2/+45
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.

2015-01-27ASoC: ts3a227e: Remap keys to match Android headset specificationAnatol Pomozov1-3/+3
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 Signed-off-by: Anatol Pomozov <anatol.pomozov@gmail.com> Acked-by: Dylan Reid <dgreid@chromium.org> Signed-off-by: Mark Brown <broonie@kernel.org>
2015-01-05ASoC: ts3a227e: Check and report jack status at probeCheng-Yi Chiang1-0/+6
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.

2014-11-14ASoC: add TI ts3a227e headset chip driverDylan Reid1-0/+314
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. Signed-off-by: Dylan Reid <dgreid@chromium.org> Signed-off-by: Mark Brown <broonie@kernel.org>
