Input: uinput - allow for 0/0 min/max on absolute axes.

Some devices provide absolute axes with min/max of 0/0 (e.g. wacom's
ABS_MISC axis). Current uinput restrictions do not allow duplication of
these devices and require hacks in userspace to work around this.

If the kernel accepts physical devices with a min/max of 0/0, uinput

Ping Cheng [Sun, 13 Mar 2011 04:34:42 +0000 (20:34 -0800)]
Input: wacom - support one finger touch the touchscreen way

There are two types of 1FGT devices supported in wacom_wac.c.
Changing them to follow the existing touchscreen format, i.e.,
only report BTN_TOUCH as a valid tool type.

Touch data will be ignored if pen is in proximity. This requires
a touch up event sent if touch was down when pen comes in. The
touch up event should be sent before any pen events are emitted.
Otherwise, two pointers would race for the cursor.

However, we can not send a touch up inside wacom_tpc_pen since
pen and touch are on different logical port. That is why we
have to check if touch is up before sending pen events.

Revert "Input: do not pass injected events back to the originating handler"

This reverts commit 5fdbe44d033d059cc56c2803e6b4dbd8cb4e5e39.

Apparently there exist userspace programs that expect to be able to
"loop back" and distribute to readers events written into
/dev/input/eventX and this change made for the benefit of SysRq
handler broke them. Now that SysRq uses alternative method to suppress
filtering of the events it re-injects we can safely revert this change.

Internally 'disable' the filter when re-injecting Alt-SysRq instead

Duncan Laurie [Thu, 3 Feb 2011 06:59:54 +0000 (22:59 -0800)]
Input: serio - clear pending rescans after sysfs driver rebind

When rebinding a serio driver via sysfs drvctl interface it is
possible for an interrupt to trigger after the disconnect of the
existing driver and before the binding of the new driver.  This will
cause the serio interrupt handler to queue a rescan event which will
disconnect the new driver immediately after it is attached.

This change removes pending rescans from the serio event queue after
processing the drvctl request but before releasing the serio mutex.

Reproduction involves issuing a rebind of device port from psmouse
driver to serio_raw driver while generating input to trigger
interrupts.  Then checking to see if the corresponding
i8042/serio4/driver is correctly attached to the serio_raw driver
instead of psmouse.

Input: wacom_w8001 - report resolution to userland

Serial devices send both pen and touch data through the same logical
port. Since we scaled touch to pen maximum, we use pen resolution
for touch as well here.

This is under the assumption that pen and touch share the same physical
surface. In the case when a small physical dimensional difference occurs
between pen and touch, we assume the tolerance for touch point precision
is higher than pen and the difference is within touch point tolerance.

A per-MT tool based resolution mechanism should be introduced if the
above assumption does not hold true for the pen and touch devices any
more.
