This patchset cleans up the atmel_mxt_ts touchscreen driver.
In particular, v2 implements the following:

1) sysfs
  a) fw_update only by root
2) faster initialization
  a) read/write sets of registers using i2c block transactions
  b) fetch object table as a set of i2c reads, one per object
  c) 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

v2:
 * Writable config via sysfs has been removed to resolve possible
   conflict with Nick Dyer's implementation.
 * Using T44 has been removed from this patchset, hopefully it can
   be reexamined after most of these patches are accepted.

The patches were tested using an MXT224E.

Joonyoung, Nick, Henrik,

Can you please take a look at this second version of the atmel_mxt_ts patches?
