linux/drivers/input/touchscreen, branch v2.6.23.4

Input: usbtouchscreen - correctly set 'phys'

2007-09-07T01:32:16Z

This patch fixes a nasty typo in usbtouchscreen driver. The typo is inherited from the original mtouchusb. It used to make the input subsytem to incorrectly report the physical device ids to userspace that in turn is very confusing for, e.g. XInput hotplug facilities in setups with multiple identical touchscreens.

Input: add driver for Fujitsu serial touchscreens

2007-07-18T04:37:01Z

These serial touchscreens are found on some Fujitsu lifebook P-series laptops, and the B6210. Using this requires a new version of inputattach and doing: inputattach -fjt /dev/ttyS0 Big thanks to Stephen Hemminger for testing it and making it work on his B6210 laptop.

Input: ads7846 - re-check pendown status before reporting events

2007-07-18T04:36:04Z

Pendown status from the PENIRQ pin is currently read only at the beginning of a sample set. If the pen is lifted just after sampling has began then sampled values become wrong. This patch adds an optional platform penirq_recheck_delay attribute. If non-zero, samples are only reported to the input subsystem if PENIRQ is still active that long after the samples taken.

Input: ads7846 - introduce sample settling delay

2007-07-18T04:35:56Z

The ads7846 driver has support for filtering, but when the chip gets deselected between samples this causes noise. This patch adds support for an optional settling delay time, so that two consecutive samples will be taken with the specified delay time apart. This ensures that the chip won't be deselected, so the noise won't appear. Filtering can still be done, but will have less work to do since each time a new sample is taken the same delay applies.

Freezer: make kernel threads nonfreezable by default

2007-07-17T17:23:02Z

Currently, the freezer treats all tasks as freezable, except for the kernel threads that explicitly set the PF_NOFREEZE flag for themselves. This approach is problematic, since it requires every kernel thread to either set PF_NOFREEZE explicitly, or call try_to_freeze(), even if it doesn't care for the freezing of tasks at all. It seems better to only require the kernel threads that want to or need to be frozen to use some freezer-related code and to remove any freezer-related code from the other (nonfreezable) kernel threads, which is done in this patch. The patch causes all kernel threads to be nonfreezable by default (ie. to have PF_NOFREEZE set by default) and introduces the set_freezable() function that should be called by the freezable kernel threads in order to unset PF_NOFREEZE. It also makes all of the currently freezable kernel threads call set_freezable(), so it shouldn't cause any (intentional) change of behaviour to appear. Additionally, it updates documentation to describe the freezing of tasks more accurately. [akpm@linux-foundation.org: build fixes] Signed-off-by: Rafael J.

Input: usbtouchscreen - add support for IRTOUCHSYSTEMS touchscreens

2007-07-10T04:35:18Z

This patch adds support for IRTOUCHSYSTEMS (or UNITOP) infrared touchscreens. The touchscreen sends data in 8-byte packets. BYTE 0 - unknown meaning, seen only one value: 0x54 BYTE 1 - unknown meaning, 3 lowest bits indicate touch state values seen: 0x81, 0x82 or 0x83 bit 0 = set if the screen is touched and was not touched before (touch bit 1 = set if the screen is touched and was touched (dragging) bit 2 = set if the touch was ended (release) BYTES 2 and 3 - X position, high-order-byte first, range = 0 to 0x0FFF BYTES 4 and 5 - Y position, high-order-byte first, range = 0 to 0x0FFF BYTE 6 - unknown meaning, seen only one value: 0xFF BYTE 7 - unknown meaning, seen only one value: 0x00 Signed-off-by: Ondrej Zary Signed-off-by: Daniel Ritz Signed-off-by: Dmitry Torokhov

Input: usbtouchscreen - fix fallout caused by move from drivers/usb

2007-06-12T04:33:13Z

During the move from drivers/usb/input into drivers/input/touchscreen Kconfig variables were shuffled a bit to use a new namespace (CONFIG_TOUCHSCREEN) while usbtouchscreen was still using old ones.

Input: ads7846 - SPI_CPHA mode bugfix

2007-05-23T03:35:12Z

In commit [1] the SPI mode is set to 1, but it should be 0. As stated in the commit, ads784x samples the data on the rising edge. SPI mode 1 samples on the falling edge [2] though. The root cause of this is a bug in the omap_uwire code, which treats CPHA=1 incorrectly; so these two bugs cancel each other out on one of the main regression test platforms for this driver.
