Commit ce53044c authored by Linus Torvalds's avatar Linus Torvalds

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

Pull arm-soc driver specific updates from Olof Johansson:
 "These changes are specific to some driver that may be used by multiple
  boards or socs.  The most significant change in here is the move of
  the samsung iommu code from a platform specific in-kernel interface to
  the generic iommu subsystem."

Fix up trivial conflicts in arch/arm/mach-exynos/Kconfig

Automatically determines which UART to use for low-level debug based
on the ODMDATA value. This value is part of the BCT, and is written
to the boot memory device using nvflash, or other flashing tool.
When bits 19:18 are 3, then bits 17:15 indicate which UART to use;
0/1/2/3/4 are UART A/B/C/D/E.

Automatically determines which UART to use for low-level debug based
on the UART scratch register value. Some bootloaders put ASCII 'D'
in this register when they initialize their own console UART output.
Using this option allows the kernel to automatically pick the same
