Merge tag 'dt-for-linus' of git://git.secretlab.ca/git/linux

Pull device tree changes from Grant Likely:
 "All around device tree changes destined for v3.8.  Aside from the
  documentation updates the highlights in this branch include:

   - Kbuild changes for using CPP with .dts files
   - locking fix from preempt_rt patchset
   - include DT alias names in device uevent
   - Selftest bugfixes and improvements
   - New function for counting phandles stanzas in a property
   - constify argument to of_node_full_name()
   - Various bug fixes

  This tree did also contain a commit to use platform_device_add instead
  of open-coding the device add code, but it caused problems with amba
  devices and needed to be reverted."
