This patchset cleans up the atmel_mxt_ts touchscreen driver. In particular, v3 implements the following:
1) sysfs a) fw_update only by root b) use sncprintf() 2) faster initialization a) read/write sets of registers using i2c block transactions b) fetch object descriptor table as a single i2c transaction c) fetch objects as a set of i2c reads, one per object d) write config data as a set of i2c writes, one per object 3) faster interrupt processing & initialization times a) cache important values at init instead of computing in isr b) don't read message checksum byte (which isn't even enabled in fw) 4) more correct MT-B support a) send all (changed) contacts in a single EV_SYN/SYN_REPORT
v3: * Address Henrik's feedback: 1) removed some more stack allocations 2) use sncprintf() in sysfs handler
The patches were tested using an MXT224E. They should apply cleanly to input/next.
