Merge tag 'dt-for-linus' of git://git.secretlab.ca/git/linux
Pull devicetree fixes from Grant Likely: "Device tree compatible match order bug fix This branch contains a bug fix for the way devicetree code identifies the type of device. Device drivers can contain a list of of_device_ids, but it more than one entry will match, then the device driver may choose the wrong one. Commit 105353145e, "match each node compatible against all given matches first", was queued for v3.14 but ended up causing other bugs. Commit 06b29e76a7 attempted to fix it but it had other bugs. Merely reverting the fix and waiting until v3.15 isn't a good option because there is code in v3.14 that depends on the revised behaviour to boot. This branch should finally fixes the problem correctly. This time instead of just hoping that the patch is correct, this branch also adds new testcases that validate the behaviour. The changes in this branch are larger than I would like for a -rc pull, but moving the test case data out of out of arch/arm so that it could be validated on other architectures was important" * tag 'dt-for-linus' of git://git.secretlab.ca/git/linux: of: Add self test for of_match_node() of: Move testcase FDT data into drivers/of of: reimplement the matching method for __of_match_node() Revert "of: search the best compatible match first in __of_match_node()"
