2017-03-16Input: tps6507x-ts - update to devm_* APIYegor Yefremov1-28/+5
Update the code to use devm_* API so that driver core will manage resources. Signed-off-by: Yegor Yefremov <yegorslists@googlemail.com> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
2015-10-02Input: tps6507x-ts - simplify function return logicJavier Martinez Canillas1-8/+1
The invoked function already returns zero on success or a negative errno code so there is no need to open code the logic in the caller. This also fixes the following make coccicheck warning: drivers/input/touchscreen/tps6507x-ts.c:57:5-8: WARNING: end returns can be simplified Signed-off-by: Javier Martinez Canillas <javier@osg.samsung.com> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
2014-10-20input: touchscreen: drop owner assignment from platform_driversWolfram Sang1-1/+0
A platform_driver does not need to set an owner, it will be populated by the driver core. Signed-off-by: Wolfram Sang <wsa@the-dreams.de>
2013-07-01Input: tps6507x-ts - convert to polled input device infrastructureDmitry Torokhov1-78/+48
There is no need to roll our own polling scheme when we already have one implemented by the core. Tested-by: Manish Badarkhe <badarkhe.manish@gmail.com> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
2013-06-25Input: tps6507x-ts - remove vref from platform dataDmitry Torokhov1-5/+0
Although defined in platform data, vref is not used anywhere. Also remove model, irq, and clear_penirq as they are not used either. Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
2013-06-25Input: tps6507x-ts - use bool for booleansDmitry Torokhov1-7/+7
Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
2013-06-25Input: tps6507x-ts - remove bogus unreachable codeAlan Cox1-20/+5
tsc->polling is write only and the poll local is meaningless Signed-off-by: Alan Cox <alan@linux.intel.com> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
2012-11-24Input: remove use of __devexitBill Pemberton1-1/+1
CONFIG_HOTPLUG is going away as an option so __devexit is no longer needed. Signed-off-by: Bill Pemberton <wfp5p@virginia.edu> Acked-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>

2012-04-03Input: tps6507x-ts - fix MODULE_ALIAS to match driver nameUwe Kleine-König1-3/+1
This is needed to make module auto loading work. [dtor@mail.ru: remove file name from comment] Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
2011-12-01Input: touchscreen - use macro module_platform_driver()JJ Ding1-12/+1
Commit 940ab88962bc1aff3273a8356d64577a6e386736 introduced a new macro to save some platform_driver boilerplate code. Use it. Signed-off-by: JJ Ding <dgdunix@gmail.com> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
2011-01-26input/tps6507x-ts: use system_wq instead of dedicated workqueueTejun Heo1-8/+4
With cmwq, there's no reason to use a separate workqueue. Drop tps6507x_ts->wq and use system_wq instead.

2010-09-03Input: tps6507x-ts - properly unregister input device on removalAxel Lin1-1/+1
Once device is registered we should call input_unregister_device() instead of input_free_device(). Signed-off-by: Axel Lin <axel.lin@gmail.com> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
2010-09-03Input: tps6507x-ts - add missing call to platform_set_drvdata()Axel Lin1-0/+1
We call platform_get_drvdata() in tps6507x_ts_remove(), thus we should call platform_set_drvdata() in tps6507x_ts_probe(). Signed-off-by: Axel Lin <axel.lin@gmail.com> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
2010-06-23Input: tps6507x-ts - remove unneeded NULL testJiri Slaby1-3/+0
Stanse found that tsc is dereferenced earlier than checked for being NULL in tps6507x_ts_remove. Remove the test because there is no way for tsc to be NULL there. Signed-off-by: Jiri Slaby <jslaby@suse.cz> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
2010-06-02Input: tps6507x-ts - a couple work queue cleanupsDan Carpenter1-8/+4
1) Use msecs_to_jiffies() instead of calculating by hand. 2) Call cancel_delayed_work_sync() instead of cancel_delayed_work() followed by a separate flush_workqueue(). 3) Remove the "tsc->wq = 0;" Sparse complains about that because tsc->wq is a pointer, not an int. It's not needed because we just free the pointer anyway. Signed-off-by: Dan Carpenter <error27@gmail.com> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
2010-05-28input: Touchscreen driver for TPS6507xTodd Fischer1-0/+400
Add touch screen input driver for TPS6507x family of multi-function chips. Uses the TPS6507x MFD driver. No interrupt support due to testing limitations of current hardware. Signed-off-by: Todd Fischer <todd.fischer@ridgerun.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
