Pull i2c fixes from Wolfram Sang:
 "i2c driver bugfixes (s3c2410, slave-eeprom, sh_mobile), size
  regression "bugfix" (i2c slave), documentation bugfix (st).

  Also, one documentation update (da9063), so some devicetrees can now
  be verified"

* 'i2c/for-current' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux:
  i2c: sh_mobile: terminate DMA reads properly
  i2c: Only include slave support if selected
  i2c: s3c2410: fix ABBA deadlock by keeping clock prepared
  i2c: slave-eeprom: fix boundary check when using sysfs
  i2c: st: Rename clock reference to something that exists
  DT: i2c: Add devices handled by the da9063 MFD driver
