Depending on the quality of the touch panel, the time for the X-, X+, Y- and Y+ inputs to settle may vary. The poll_delay parameter can be used to override the default of 1 millisecond.

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.

As reported by Jean-Francois Dagenais, the wheel algorithm caused a divide by zero exception due to missing variable pre-initialization. In fact it turned out that the whole algorithm had several problems. It is therefore replaced with something that is known working.

Apparently somewhere someone had a proprietary X driver. To get the multitouch info, it uses some hack on the normal API instead of using the multitouch protocol. Now that the multitouch info is transmitted correctly it makes not much sense to keep it. Especially because it's impossible to find this proprietary X driver anywhere, so the number of users must be very low.

Multitouch info was reported only via a old protocol used by the proprietary X driver from elantech. Let's report the multitouch info also following the official MT protocol. It's semi-mt because the device only reports the lowest/highest coordinates. This was done following the multi-touch-protocol.txt documentation, and inspired by the bcm5974 and elantech implementations. Testing was light as there is not many applications using this protocol yet, but the X synaptics driver didn't complain and the X multitouch driver behaved correctly.

For some Dell laptops, Ubuntu had a special version of the elantech driver with more knowledge on the devices. It can be found there: http://zinc.ubuntu.com/git?p=mid-team/hardy-netbook.git;a=blob;f=drivers/input/mouse/elantech.c;h=d0e2cafed162428f72e3654f4dda85e08ea486b3;hb=refs/heads/abi-22 By inspecting the source code, and doing some test on a real hardware, I have completed the protocol specification (especially for the 6 bytes protocol). It also adds information about the mapping between the version reported by the device and the protocol to use.

Update the KEYSC driver to make use of threaded IRQs with IRQF_ONESHOT to improve interrupt latency. The driver is using udelay() in the ISR to make sure the hardware has stabilized. Without using interrupt threads this delay may affect the latency of the rest of the system. Also pass dev_name() as string for /proc/interrupts.

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.
