[PATCH 00/20] cleanup atmel_mxt_ts

[Daniel Kurtz <djkurtz@chromium.org>]

This patchset cleans up the atmel_mxt_ts touchscreen driver.
In particular, it addresses the following issues:

1) sysfs
   a) fw_update only by root
   b) allow writing config
   c) add backupnv to save config to device flash
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)
   c) read num messages first, instead of looking for 0xFF reportid
   d) read all pending message bytes in one i2c read transaction
4) more correct MT-B support
   a) send all (changed) contacts in a single EV_SYN/SYN_REPORT
