Input: smtpe-ts - wait 50mS until polling for pen-up

2015-05-22T00:06:13Z

Wait a little bit longer, 50mS instead of 20mS, until the driver starts polling for pen-up. The problematic behavior before this patch is applied is as follows. The behavior was observed on the STMPE610QTR controller. Upon a physical pen-down event, the touchscreen reports one set of x-y-p coordinates and a pen-down event. After that, the pen-up polling is triggered and since the controller is not ready yet, the polling mistakenly detects a pen-up event while the physical state is still such that the pen is down on the touch surface. The pen-up handling flushes the controller FIFO, so after that, all the samples in the controller are discarded. The controller becomes ready shortly after this bogus pen-up handling and does generate again a pen-down interrupt. This time, the controller contains x-y-p samples which all read as zero. Since pressure value is zero, this set of samples is effectively ignored by userland. In the end, the driver just bounces between pen-down and bogus pen-up handling, generating no useful results. Fix this by giving the controller a bit more time before polling it for pen-up. Signed-off-by: Marek Vasut Reviewed-by: Viresh Kumar Signed-off-by: Dmitry Torokhov

Input: smtpe-ts - use msecs_to_jiffies() instead of HZ

2015-05-22T00:05:48Z

Use msecs_to_jiffies(20) instead of plain (HZ / 50), as the former is much more explicit about it's behavior. We want to schedule the task 20 mS from now, so make it explicit in the code. Signed-off-by: Marek Vasut Reviewed-by: Viresh Kumar 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: delete non-required instances of include

2014-01-07T07:23:57Z

None of these files are actually using any __init type directives and hence don't need to include . Most are just a left over from __devinit and __cpuinit removal, or simply due to code getting copied from one driver to the next. Signed-off-by: Paul Gortmaker Signed-off-by: Dmitry Torokhov

Input: stmpe-ts - report BTN_TOUCH event

stmpe touchscreen supports BTN_TOUCH event but doesn't report it. Add BTN_TOUCH reporting capability to the stmpe touchscreen driver. Signed-off-by: Vipul Kumar Samar Reviewed-by: Viresh Kumar Acked-by: Lee Jones Signed-off-by: Dmitry Torokhov
