Input: mc13783_ts - remove deprecated create_singletheread_workqueue

2016-08-25T17:11:00Z

The workqueue "workqueue" has a single workitem(&priv->work) and hence doesn't require ordering. Also, it is not being used on a memory reclaim path. Hence, the singlethreaded workqueue has been replaced with the use of system_wq. System workqueues have been able to handle high level of concurrency for a long time now and hence it's not required to have a singlethreaded workqueue just to gain concurrency. Unlike a dedicated per-cpu workqueue created with create_singlethread_workqueue(), system_wq allows multiple work items to overlap executions even on the same CPU; however, a per-cpu workqueue doesn't have any CPU locality or global ordering guarantee unless the target CPU is explicitly specified and thus the increase of local concurrency shouldn't make any difference. Workitem is sync cancelled in mc13783_ts_remove() to ensure that there are no workitems pending when the driver is disconnected. Signed-off-by: Bhaktipriya Shridhar Signed-off-by: Dmitry Torokhov

input: touchscreen: drop owner assignment from platform_drivers

2014-10-20T14:20:41Z

A platform_driver does not need to set an owner, it will be populated by the driver core. Signed-off-by: Wolfram Sang

Input: mc13783_ts - remove redundant platform_set_drvdata()

2013-05-06T03:14:52Z

Commit 0998d06310 (device-core: Ensure drvdata = NULL when no driver is bound) removes the need to set driver data field to NULL. Signed-off-by: Sachin Kamat Signed-off-by: Dmitry Torokhov

Input: mc13783_ts - use module_platform_driver_probe()

2013-03-18T04:37:39Z

This patch converts the drivers to use the module_platform_driver_probe() macro which makes the code smaller and a bit simpler. Signed-off-by: Fabio Porcedda Signed-off-by: Dmitry Torokhov

Input: remove use of __devexit

CONFIG_HOTPLUG is going away as an option so __devexit is no longer needed. Signed-off-by: Bill Pemberton Acked-by: Mark Brown Signed-off-by: Dmitry Torokhov

Input: remove use of __devexit_p

mfd: Add pdata to set mc13783-ts conversion delay

2012-03-06T17:46:30Z

MC13783 can be programmed to wait some clock cycles between the touchscreen polarization and the resistance conversion. This is needed to adjust for touchscreens with high capacitance between plates.

Input: revert some over-zealous conversions to module_platform_driver()

2012-01-11T07:12:46Z

Recent conversion to module_platform_driver() went a bit too far and converted not only drivers that used platform_driver_register() but also ones using platform_driver_probe(), breaking them in process. Reported-by: Geert Uytterhoeven Signed-off-by: Dmitry Torokhov

Input: touchscreen - use macro module_platform_driver()

2011-12-01T07:41:43Z

Commit 940ab88962bc1aff3273a8356d64577a6e386736 introduced a new macro to save some platform_driver boilerplate code. Use it. Signed-off-by: JJ Ding Signed-off-by: Dmitry Torokhov

input: Convert mc13783-ts to mc13xxx API
