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
