Merge tag 'drivers' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull "ARM: driver specific updates" from Arnd Bergmann:
 "These are all specific to some driver.  They are typically the
  platform side of a change in the drivers directory, such as adding a
  new driver or extending the interface to the platform.  In cases where
  there is no maintainer for the driver, or the maintainer prefers to
  have the platform changes in the same branch as the driver changes,
  the patches to the drivers are included as well.

  A much smaller set of driver updates that depend on other branches
  getting merged first will be sent later.

  The new export of tegra_chip_uid conflicts with other changes in
  fuse.c.  In rtc-sa1100.c, the global removal of IRQF_DISABLED
  conflicts with the cleanup of the interrupt handling of that driver.

  Signed-off-by: Arnd Bergmann <arnd@arndb.de>"

Fixed up aforementioned trivial conflicts.
