bcma: use NS prefix for names of Northstar specific cores

2014-07-31T17:45:32+00:00

It's cleaner and we don't have quite identical names like
BCMA_CORE_PCIEG2 and BCMA_CORE_PCIE2.

b43: add support for BCM43131 chipset with N-PHY rev 17

2014-07-29T14:32:57+00:00

It contains radio 0x2057 rev 14 just like a BCM43217, so it doesn't
require any magic. The main difference is that BCM4313 is 1x1:1.

bcma: add driver for PCIe Gen 2 core

2014-07-07T20:32:16+00:00

New Broadcom PCIe devices (802.11ac ones?) use Gen2 and have to be
initialized differently.

Merge branch 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus

2014-01-31T01:20:32+00:00

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"

bcma: gpio: add own IRQ domain

2014-01-23T12:02:37+00:00

Input GPIO changes can generate interrupts, but we need kind of ACK for
them by changing IRQ polarity. This is required to stop hardware from
keep generating interrupts and generate another one on the next GPIO
state change.
This code allows using GPIOs with standard interrupts and add for
example GPIO buttons support.

bcma: make bcma_core_pci_{up,down}() callable from atomic context

2013-09-26T18:02:33+00:00

This patch removes the bcma_core_pci_power_save() call from
the bcma_core_pci_{up,down}() functions as it tries to schedule
thus requiring to call them from non-atomic context. The function
bcma_core_pci_power_save() is now exported so the calling module
can explicitly use it in non-atomic context. This fixes the
'scheduling while atomic' issue reported by Tod Jackson and
Joe Perches.
