2011-09-08Input: wacom - add POINTER and DIRECT device propertiesJason Gerecke
Adds INPUT_PROP_POINTER or INPUT_PROP_DIRECT as necessary to the hardware supported by the Wacom driver. The DIRECT property is assigned to devices with an embedded screen (i.e. touchscreens and display tablets). The POINTER property is assigned to those without embedded screens.

2011-07-04Input: wm97xx - mark channels which need pen_downWolfram Sang
Currently, battery drivers also use poll_sample() provided by the wm97xx-core but this code always checks if the pen is down. Mark the channels which really need this (i.e. for the touchscreen) with the PEN_DOWN bit, and skip the checks otherwise. Now, the battery channels can always be read.

2011-07-04Input: wm97xx - refactor channel selection in poll_sample()Wolfram Sang
The current implementation of poll_sample() has the problem that one of its arguments, the channel to be selected, differs from wm9713 to other variants. This parameter gets passed to the (currently unused) mach-specific functions pre_sample() and post_sample() which thus have to deal with codec-specific differences. Refactor the routine so that the argument to poll_sample() is generic for all codecs and do necessary conversions only in the codec-specific driver. The outcome even uses less code and removes the non-standard use of the PEN_DOWN bit to mark the AUX-channels.

2011-05-17Input: tsc2007 - add poll_delay parameter to platform dataThierry Reding

2011-05-17Input: tsc2007 - add max_rt parameter to platform dataThierry Reding
Finger touch events or very quick stylus events on low-quality panels can cause the tsc2007 to read bogus values. Looking at oscilloscope snapshots, this seems to be caused by the touch event disappearing during the measurements. These bogus values result in misclicks, where the X and Y values deviate from the real position. Most of these misclicks can be filtered out by setting a low enough threshold for the maximum resistance (which is loosely the inverse of the pressure) allowed to consider a set of values valid. Since this behaviour is largely dependent on the type and quality of the panel, this commit introduces the max_rt parameter. The default value is kept at MAX_12BIT.

2011-04-27Input: wm831x-ts - move BTN_TOUCH reporting to data transferMark Brown

2011-04-27Input: wm831x-ts - fix races with IRQ managementMark Brown
If the WM831x pen down and data IRQs run in parallel it is possible for the data and pen down IRQs to deadlock themselves as one is part way through disabling its operation while the other is part way through enabling. Fix this by always disabling the pen down interrupt while data is active and vice versa. When a changeover is required we disable the IRQ that is to be stopped then schedule work that will enable the new IRQ. We need to handle the data flow in the data IRQ as the readback from the device needs to be ordered correctly with the IRQ for robust operation. This also fixes an issue when using the built in IRQs due to enable_irq() not being valid from interrupt context on an interrupt controller with bus operations like the built in IRQ controller - this issue may also have affected other interrupt controllers. We can't rely on having the data and pen down IRQs available via GPIOs on the CPU on every system.

Commit 0b950d3 (Input: tsc2005 - add open/close) introduced a locking issue with the ESD watchdog: __tsc2005_disable() is calling cancel_delayed_work_sync() with mutex held, and the work also needs the same mutex. Fix the problem by using mutex_trylock() in tsc2005_esd_work(). If the mutex is taken, we know we are in the middle of disable or enable and the watchdog check can be skipped.
