Input: stmpe-ts: preparations for STMPE ADC driver

2019-01-16T12:36:26Z

This patch removes common ADC settings in favor to use stmpe811_adc_common_init that is present in MFD. This is necessary in preparation for the stmpe-adc driver, because those two drivers have common settings for the ADC.

mfd: stmpe: Move ADC related defines to MFD header

2019-01-16T12:35:41Z

Move defines that are ADC related to the header of the overlying MFD, so they can be used from multiple sub-devices. Signed-off-by: Philippe Schenker Acked-by: Dmitry Torokhov Signed-off-by: Lee Jones

Input: stmpe-ts - restore kerneldoc

commit e4b88e19897f1039fd83f1630517becafc0dd163 "Input: stmpe-ts - enforce device tree only mode" removed platform data but accidentally stripped away useful kerneldoc, so reintroduce it. Signed-off-by: Linus Walleij Signed-off-by: Dmitry Torokhov

Input: stmpe-ts - enforce device tree only mode

2015-05-26T21:16:08Z

The STMPE MFD is only used with device tree configured systems (and STMPE MFD core depends on OF), so force the configuration to come from device tree only. Tested-by: Heiner Kallweit Reviewed-by: Marek Vasut Acked-by: Lee Jones Signed-off-by: Dmitry Torokhov

Input: stmpe-ts - fix automatic module loading

2015-05-22T22:30:11Z

When STMPE is instantiated via device tree individual MFD cells rae formed with OF modaliases, not platform modaliases, and so we need to add OF device table to the driver if we want it to load automatically: of:Nstmpe_touchscreenTCst,stmpe-ts Reported-by: Heiner Kallweit Tested-by: Heiner Kallweit Signed-off-by: Dmitry Torokhov

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

2015-05-08T05:30:18Z

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

2015-05-08T05:30:17Z

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

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
