Merge tag 'devicetree-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/glikely/linux
Pull devicetree changes from Grant Likely: "Here are the devicetree changes queued up for v4.1. Nothing really exciting here. Rob has another few commits for big-endian attached UARTs, but those will be sent in a separate merge request since they haven't been as thoroughly tested as this batch. Here are the highlights: - lots of unittest cleanup from Frank Rowand - bugfixes and updates to the of_graph code - tighten up of_get_mac_address() code - documentation updates" * tag 'devicetree-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/glikely/linux: of/unittest: Fix of_platform_depopulate test case of/unittest: early return from test skips tests of/unittest: breadcrumbs to reduce pain of future maintainers of/unittest: reduce checkpatch noise - line after declarations of/unittest: typo in error string of/unittest: add const where needed of_net: factor out repetitive code from of_get_mac_address() drivers/of: Add empty ranges quirk for PA-Semi of: Allow selection of OF_DYNAMIC and OF_OVERLAY if OF_UNITTEST of: Empty node & property flag accessors when !OF of: Explicitly include linux/types.h in of_graph.h dt-bindings: brcm: rationalize Broadcom documentation naming of/unittest: replace 'selftest' with 'unittest' Documentation: rename of_selftest.txt to of_unittest.txt Documentation: update the of_selftest.txt dt: OF_UNITTEST make dependency broken MAINTAINERS: Pantelis Antoniou device tree overlay maintainer of: Add of_graph_get_port_by_id function of: Add for_each_endpoint_of_node helper macro of: Decrement refcount of previous endpoint in of_graph_get_next_endpoint
