Commit 09893ee8 authored by Linus Torvalds's avatar Linus Torvalds

Merge tag 'dt2' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull "ARM: More device tree support updates" from Olof Johansson:
 "This branch contains a number of updates for device tree support on
  several ARM platforms, in particular:

   * AT91 continues the device tree conversion adding support for a
     number of on-chip drivers and other functionality
   * ux500 adds probing of some of the core SoC blocks through device
     tree
   * Initial device tree support for ST SPEAr600 platforms
   * kirkwood continues the conversion to device-tree probing"

Manually merge arch/arm/mach-ux500/Kconfig due to MACH_U8500 rename, and
drivers/usb/gadget/at91_udc.c due to header file include cleanups.

Also do an "evil merge" for the MACH_U8500 config option rename that the
affected RMI4 touchscreen driver in staging.  It's called MACH_MOP500
now, and it was missed during previous merges.

Optional properties:
- dr_mode : dual role mode. Indicates the working mode for
nvidia,tegra20-ehci compatible controllers. Can be "host", "peripheral",

host means this is a host controller
peripheral means it is device controller
otg means it can operate as either ("on the go")
- nvidia,has-legacy-mode : boolean indicates whether this controller can
operate in legacy mode (as APX 2500 / 2600). In legacy mode some
registers are accessed through the APB_MISC base address instead of
the USB controller. Since this is a legacy issue it probably does not
warrant a compatible string of its own.
