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." * tag 'dt-for-linus' of git://git.secretlab.ca/git/linux: (23 commits) Revert "of: use platform_device_add" kbuild: limit dtc+cpp include path gpio: Make of_count_named_gpios() use new of_count_phandle_with_args() of: Create function for counting number of phandles in a property of/base: Clean up exit paths for of_parse_phandle_with_args() of/selftest: Use selftest() macro throughout of/selftest: Fix GPIOs selftest to cover the 7th case of: fix recursive locking in of_get_next_available_child() documentation/devicetree: Fix a typo in exynos-dw-mshc.txt OF: convert devtree lock from rw_lock to raw spinlock of/exynos_g2d: Add Bindings for exynos G2D driver kbuild: create a rule to run the pre-processor on *.dts files input: Extend matrix-keypad device tree binding devicetree: Move NS2 LEDs binding into LEDs directory of: use platform_device_add powerpc/5200: Fix size to request_mem_region() call documentation/devicetree: Fix typos of: add 'const' to of_node_full_name parameter of: Output devicetree alias names in uevent DT: add vendor prefixes for Renesas and Toshiba ...
