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."
