Pull MIPS updates from Ralf Baechle:
 "This is the main pull request for MIPS for 4.5 plus some 4.4 fixes.

  The executive summary:

   - ATH79 platform improvments, use DT bindings for the ATH79 USB PHY.
   - Avoid useless rebuilds for zboot.
   - jz4780: Add NEMC, BCH and NAND device tree nodes
   - Initial support for the MicroChip's DT platform.  As all the device
     drivers are missing this is still of limited use.
   - Some Loongson3 cleanups.
   - The unavoidable whitespace polishing.
   - Reduce clock skew when synchronizing the CPU cycle counters on CPU
     startup.
   - Add MIPS R6 fixes.
   - Lots of cleanups across arch/mips as fallout from KVM.
   - Lots of minor fixes and changes for IEEE 754-2008 support to the
     FPU emulator / fp-assist software.
   - Minor Ralink, BCM47xx and bcm963xx platform support improvments.
   - Support SMP on BCM63168"

3d1f664ab9 MIPS: BCM47xx: Support SPROM prefixes on other platforms
BCM47XX platform has specific PCI setup because all buses share the same
domain. It's different e.g. on ARM ARCH_BCM_5301X where each PCI bus
gets its own domain (they are handled by iProc PCIe controller driver).

As we want to make SPROM driver more generic, let's add an exception for
BCM47xx. It was tested on BCM4706 (MIPS) and BCM4708A0 (ARM).

541c9a84cd ssb: pick SoC invariants code from MIPS BCM47xx arch
There is code in ssb fetching "invariants" that is basically a set of
board specific data. Every host requires its own implementation of
reading function. In ssb we have support for PCI, PCMCIA & SDIO.
For some (historical?) reason code reading "invariants" for SoC was
placed in arch code and provided by a callback. This is not needed
nowadays, so lets move that into ssb. This way we keep all "invariants"
functions in a single module making code cleaner.

daa7ce0251 MIPS: BCM47xx: Support on-SoC bus in SPROM reading function
To support (extract) SPROM on Broadcom ARM devices we should separate
SPROM code and make it a separated module. We won't want to export
bcm47xx_fill_sprom symbol so we should support SoC SPROM in the standard
fallback function and then modify ssb to use it.

Pull MIPS updates from Ralf Baechle:
 "This is the main pull request for 4.3 for MIPS.  Here's the summary:

  Three fixes that didn't make 4.2-stable:

   - a -Os build might compile the kernel using the MIPS16 instruction
     set but the R2 optimized inline functions in <uapi/asm/swab.h> are
     implemented using 32-bit wide instructions which is invalid.

   - a build error in pgtable-bits.h for a particular kernel
     configuration.

   - accessing registers of the CM GCR might have been compiled to use
     64 bit accesses but these registers are onl 32 bit wide.

  And also a few new bits:

   - move the ATH79 GPIO driver to drivers/gpio

   - the definition of IRQCHIP_DECLARE has moved to linux/irqchip.h,
     change ATH79 accordingly.

   - fix definition of pgprot_writecombine

   - add an implementation of dma_map_ops.mmap

   - fix alignment of quiet build output for vmlinuz link

   - BCM47xx: Use kmemdup rather than duplicating its implementation

   - Netlogic: Fix 0x0x prefixes of constants.

   - merge Bjorn Helgaas' series to remove most of the weak keywords
     from function declarations.

   - CP0 and CP1 registers are best considered treated as unsigned
     values to avoid large values from becoming negative values.

   - improve support for the MIPS GIC timer.

   - enable common clock framework for Malta and SEAD3.

   - a number of improvments and fixes to dump_tlb().

   - document the MIPS TLB dump functionality in Magic SysRq.

   - Cavium Octeon CN68XX improvments.

   - NetLogic improvments.

   - irq: Use access helper irq_data_get_affinity_mask.

   - handle MSA unaligned accesses.

   - a number of R6-related math-emu fixes.

   - support for I6400.

   - improvments to MSA support.

   - add uprobes support.

   - move from deprecated __initcall to arch_initcall.

   - remove finish_arch_switch().

   - IRQ cleanups by Thomas Gleixner.

   - migrate to new 'set-state' interface.

   - random small cleanups"

590605c6bc MIPS: BCM47xx: Simplify handling SPROM revisions
After the big SPROM cleanup moving code to the bcm47xx_sprom_fill_auto

This also stops extracting higher SPROM revisions as revision 1. Now we
have that function nicely handling revisions we don't need it.

f6e734a8c1 MIPS: BCM47xx: Move NVRAM driver to the drivers/firmware/
After Broadcom switched from MIPS to ARM for their home routers we need
to have NVRAM driver in some common place (not arch/mips/). As explained
in Kconfig, this driver is responsible for parsing SoC configuration
data that is passed to the kernel in flash from the bootloader firmware
called "CFE".

We were thinking about putting it in bus directory, however there are
two possible buses for MIPS: drivers/ssb/ and drivers/bcma/. So this
won't fit there and this is why I would like to move this driver to the
drivers/firmware/.

94a0535baf MIPS: BCM47xx: Add helper variable for storing NVRAM length
This simplifies code just a bit (also maybe makes it a bit more
intuitive?) and will allow us to stop storing header. Right now we copy
whole NVRAM including its header to the internal buffer. It is not
needed to store a header as we don't access all these details like CRC,
flags, etc. The next improvement that should follow is copying only the
real contents.

e754dfcfe3 MIPS: BCM47xx: Move filling most of SPROM to the generic function
This simplifies code a lot by dropping many per-revision-group
functions. There are still some paths left that use uncommon NVRAM read
helpers or fill arrays. They will need to be handled in separated patch.

I've tested this (by printing SPROM content) for regressions on:
1) BCM4704 (SPROM revision 2)
2) BCM4706 (SPROM revision 8 plus 11 & 9 on extra WiFi cards)
The only difference is not reading board_type from SPROM rev 11 which is
unsupported and treated as rev 1. This change for rev 1 is expected.

that will contain revision bitmask for every SPROM variable.

40d12172c8 MIPS: BCM47XX: Don't try guessing NVRAM size on MTD partition
When dealing with whole flash content (bcm47xx_nvram_init_from_mem) we
need to find NVRAM start trying various partition sizes (nvram_sizes).
This is not needed when using MTD as we have direct partition access.

For years Broadcom devices use 64 KiB NVRAM partition size and some of
them indeed have it filled in more than 50%. This change allows reading
whole NVRAM e.g. on Netgear WNDR4500 and Netgear R8000.

138173d4e8 MIPS: BCM47xx: Move NVRAM header to the include/linux/.
There are two reasons for having this header in the common place:
1) Simplifying drivers that read NVRAM entries. We will be able to
   safely call bcm47xx_nvram_* functions without #ifdef-s.
2) Getting NVRAM driver out of MIPS arch code. This is needed to support
   BCM5301X arch which also requires this NVRAM driver. Patch for that
   will follow once we get is reviewed.

John W. Linville says:

====================
pull request: wireless-next 2014-09-22

Please pull this batch of updates intended for the 3.18 stream...

For the mac80211 bits, Johannes says:

"This time, I have some rate minstrel improvements, support for a very
small feature from CCX that Steinar reverse-engineered, dynamic ACK
timeout support, a number of changes for TDLS, early support for radio
resource measurement and many fixes. Also, I'm changing a number of
places to clear key memory when it's freed and Intel claims copyright
for code they developed."

For the bluetooth bits, Johan says:

"Here are some more patches intended for 3.18. Most of them are cleanups
or fixes for SMP. The only exception is a fix for BR/EDR L2CAP fixed
channels which should now work better together with the L2CAP
information request procedure."

For the iwlwifi bits, Emmanuel says:

"I fix here dvm which was broken by my last pull request. Arik
continues to work on TDLS and Luca solved a few issues in CT-Kill. Eyal
keeps digging into rate scaling code, more to come soon. Besides this,
nothing really special here."

Beyond that, there are the usual big batches of updates to ath9k, b43,
mwifiex, and wil6210 as well as a handful of other bits here and there.
Also, rtlwifi gets some btcoexist attention from Larry.

Please let me know if there are problems!
====================

Had to adjust the wil6210 code to comply with Joe Perches's recent
change in net-next to make the netdev_*() routines return void instead
of 'int'.

2727cab25a MIPS: BCM47XX: Fix reboot problem on BCM4705/BCM4785
This adds some code based on code from the Broadcom GPL tar to fix the
reboot problems on BCM4705/BCM4785. I tried rebooting my device for ~10
times and have never seen a problem. This reverts the changes in the
previous commit and adds the real fix as suggested by Rafał.

Setting bit 22 in Reg 22, sel 4 puts the BIU (Bus Interface Unit) into
async mode.

The previous commit was 316cad5c1d [MIPS:
