2011-10-12Input: twl6040: Simplify vibra regsiter definitionsPeter Ujfalusi
The bits within the two control registers (for left and right channel) are identical. Use common names for the bits acros the two register. Also add the missing definition for the path selection bit.

2011-10-11Input: tsc2007 - make sure that X plate resistance is specifiedPhilip Rakity
Abort driver initialization if X plate resistance was not specified in platform data as it will cause pressure to be always calculated as 0, and making userspace ignore touch coordinates. Signed-off-by: Philip Rakity <prakity@marvell.com> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
2011-10-10Input: serio_raw - fix memory leak when closing char deviceDmitry Torokhov
Apparently we never freed memory allocated when users open our char devices nor removed old users from the list of connected clients. Also unregister misc device immediately upon disconnecting the port instead of waiting until last user drops off (refcounting in misc device code will make sure needed pieces stay around while they are needed) and make sure we are not holing holding serio_raw_mutex when registering/unregistering misc device. This should fix potential deadlock between serio_raw and misc device code uncovered by lockdep and reported by Thomas Tuttle.

2011-10-10Input: serio_raw - kick clients when disconnecting portDmitry Torokhov
Send SIGIO/POLL_HUP and otherwise wake up waiters when corresponding serio port is being disconnected. Also check if port is dead in serio_raw_poll and signal POLLHUP|POLLERR.

2011-10-10Input: serio_raw - explicitly mark disconnected ports as deadDmitry Torokhov
Instead of relying on setting serio_raw->serio to NULL upon disconnecting ports mark them explicitly as "dead".

2011-10-06Input: atmel_mxt_ts - use snprintf for sysfs attribute show methodDaniel Kurtz
Sysfs attribute show methods are always passed a buffer of length PAGE_SIZE. To keep from overwriting this buffer and causing havoc, use snprintf() to guarantee we never write more than the buffer can hold. In addition, at least for my touchscreen, the number and size of objects was far too big to fit in a single 4K page. Therefore, this patch also trims some redundant framing text to leave more room for actual data.

V2 hardware has many variants. This patch adddresses two issues: - some model also has debounce packets, but with a different signature than v3. Now we just check debounce for all v2 hardware. - due to different scanning methods the hardware uses, x and y ranges have to be calculated differently. And for some specific versions, we can just see them as custom-made, so set {x, y} the same values as Windows driver does.

Bamboos with Product ID's > 0xD4 return values unrelated to pressure in touch 1 pressure field. They also report 2nd touch X/Y values shifted down 1 byte (where pressure was). This results in jumpy 1 finger touch and totally invalid 2nd finger data. For touch detection, switch to a Touch Present single bit that all versions of Bamboo support. For touch 2 offset, calculate offset based on a bit that is set different between the two packet layouts. Since touch pressure reports were removed from driver, there was no need to be reading pressure any more.
