2010-06-01ccwmx51: Touchscreen through PMIC issuesAlejandro Gonzalez
When the touchscreen is touched the mxc_ts kernel thread uses around 30% of the CPU power continuously even is the touchscreen is no longer used. Also, once the thread is running, the reset button no longer resets the board. This fixes both issues. Signed-off-by: Alejandro Gonzalez <alex.gonzalez@digi.com>

2010-04-24mxc_ts: improved wait on irq support, avoding a race conditionPedro Perez de Heredia
This commit improves (but not fixes) a problem detected with the touch driver, that was missing an interrupt condition (a pen down after a pen up) and was causing that the driver were not able to detect additional interrupts if the pen was down, because there were no new interrupts generated. Thsi workarounds the problem by forcing the driver to wait on interrupts only after 2 consecutive pen-up samples. This seems to fix the problem, but its not 100 sure because the problem has not been analyzed with enough detail. Signed-off-by: Pedro Perez de Heredia <pedro.perez@digi.com>

Sometimes, when using the touchscreen, it stops working till next restart and the following message is printed: ucb1400: unexpected IE_STATUS = 0x0 The following patch retriggers the touchscreen interrupt unconditionally.

2009-08-21Input: ucb1400_ts - enable ADC FilterMarek Vasut
This patch enables ADC filtering on UCB1400 codec by default. The benefit from this change is mostly on some Colibri boards where the ADCSYNC pin of the UCB1400 codec isn't connected causing the touchscreen to jitter very badly. This change has no visible effect on boards where the ADCSYNC pin is connected.

2009-08-12Input: joydev - decouple axis and button map ioctls from input constantsStephen Kitt
The KEY_MAX change in 2.6.28 changed the values of the JSIOCSBTNMAP and JSIOCGBTNMAP constants; software compiled with the old values no longer works with kernels following 2.6.28, because the ioctl switch statement no longer matches the values given by the software. This patch handles these ioctls independently of the length of data specified, and applies the same treatment to JSIOCSAXMAP and JSIOCGAXMAP which currently depend on ABS_MAX.

The Prestigio 157, an old no-name clone laptop uses input keys very similar to the Wistron 1557/MS2141 with the addition of BIOS-controlled wireless radio frequency kill switch. This patch adds support for the RF kill switch control and adds manual identification of the model.

2009-07-13Input: fix EVIOCGNAME/JSIOCGNAME regressionDaniel Mack
Commit 3d5cb60e ("Input: simplify name handling for certain input handles") introduced a regression for the EVIOCGNAME/JSIOCGNAME ioctl. Before this, patch, the platform device's name was given back to userspace which was good to identify devices. After this patch, the device is ("event%d", minor) which is not descriptive at all. This fixes the behaviour by taking dev->name.

2009-07-12Input: wistron_btns - recognize Maxdata Pro 7000 notebooksGiuseppe Mazzotta
This patch adds DMI information to automatically load the correct layout for the Maxdata Pro 7000X/DX notebook models. Such notebooks are clones of Fujitsu Amilo V2000, the hook for the v2000 is being used and I have tested that perfectly works. The immediate result of integrating this patch is that the five special buttons will work on these specific notebook models and that the RF killswitch will not be activated after suspend. This patch definitively obsoletes the fsam7400 module which I was still needing to enable wifi and to fix the RF killswitch suspend problem; in the current 2.6.30 kernel it is necessary to load the wistron_btns module with options 'force=1 keymap=1557/MS2141', which was not anyway a complete workaround.

Serio ports are not being restarted any longer because resume operations after hibernate do nothing, since the device has not been marked as suspended. This happens because suspend is only considering the SUSPEND event but not the FREEZE event. Note that this driver has still to migrate to dev_pm_ops, but this fixes this particular bug now.

2009-06-29Input: add support for generic GPIO-based matrix keypadEric Miao
Original patch by Marek Vasut, modified by Eric in: 1. use delayed work to simplify the debouncing 2. combine col_polarity/row_polarity into a single active_low field 3. use a generic bit array based XOR algorithm to detect key press/release, which should make the column assertion time shorter and code a bit cleaner 4. remove the ALT_FN handling, which is no way generic, the ALT_FN key should be treated as no different from other keys, and translation will be done by user space by commands like 'loadkeys'. 5. explicitly disable row IRQs and flush potential pending work, and schedule an immediate scan after resuming as suggested by Uli Luckas 6. incorporate review comments from many others Patch tested on Littleton/PXA310 (though PXA310 has a dedicate keypad controller, I have to configure those pins as generic GPIO to use this driver, works quite well, though), and Sharp Zaurus model SL-C7x0 and SL-C1000.
