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.

2011-09-20Input: elantech - better support all those v2 variantsJJ Ding
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.

2011-09-12Input: wacom - fix touch parsing on newer BamboosChris Bagwell
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.
