Merge tag 'dt-for-linus' of git://git.secretlab.ca/git/linux-2.6
Pull core device tree changes for Linux v3.4 from Grant Likely: "This branch contains a minor documentation addition, a utility function for parsing string properties needed by some of the new ARM platforms, disables dynamic DT code that isn't used anywhere but on a few PPC machines, and exports DT node compatible data to userspace via UEVENT properties. Nothing earth shattering here." * tag 'dt-for-linus' of git://git.secretlab.ca/git/linux-2.6: of: Only compile OF_DYNAMIC on PowerPC pseries and iseries arm/dts: OMAP3: Add omap3evm and am335xevm support drivercore: Output common devicetree information in uevent of: Add of_property_match_string() to find index into a string list
