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
