Merge branch 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus
Pull MIPS updates from Ralf Baechle:
o Add basic support for the Mediatek/Ralink Wireless SoC family.
o The Qualcomm Atheros platform is extended by support for the new
QCA955X SoC series as well as a bunch of patches that get the code
ready for OF support.
o Lantiq and BCM47XX platform have a few improvements and bug fixes.
o MIPS has sent a few patches that get the kernel ready for the
upcoming microMIPS support.
o The rest of the series is made up of small bug fixes and cleanups
that relate to various parts of the MIPS code. The biggy in there is
a whitespace cleanup. After I was sent another set of whitespace
cleanup patches I decided it was the time to clean the whitespace
"issues" for once and and that touches many files below arch/mips/.
Fix up silly conflicts, mostly due to whitespace cleanups.
