Merge branch 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus
Pull MIPS updates from Ralf Baechle:
"More hardware support across the field including a bunch of device
drivers. The highlight however really are further steps towards
device tree.
This has been sitting in -next for ages. All MIPS _defconfigs have
been tested to boot or where I don't have hardware available, to at
least build fine."
