Merge branch 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus
Pull MIPS updates from Ralf Baechle:
"The most notable new addition inside this pull request is the support
for MIPS's latest and greatest core called "inter/proAptiv". The
patch series describes this core as follows.
"The interAptiv is a power-efficient multi-core microprocessor
for use in system-on-chip (SoC) applications. The interAptiv combines
a multi-threading pipeline with a coherence manager to deliver improved
computational throughput and power efficiency. The interAptiv can
contain one to four MIPS32R3 interAptiv cores, system level
coherence manager with L2 cache, optional coherent I/O port,
and optional floating point unit."
The platform specific patches touch all 3 Broadcom families. It adds
support for the new Broadcom/Netlogix XLP9xx Soc, building a common
BCM63XX SMP kernel for all BCM63XX SoCs regardless of core type/count
and full gpio button/led descriptions for BCM47xx.
The rest of the series are cleanups and bug fixes that are MIPS
generic and consist largely of changes that Imgtec/MIPS had published
in their linux-mti-3.10.git stable tree. Random other cleanups and
patches preparing code to be merged in 3.15"
