Paul Mundt afae021abe sh: pfc: Shuffle PFC support core.
This follows the intc/clk changes and shuffles the PFC support code under
its own directory. This will facilitate better code sharing, and allow us
to trim down the exported interface by quite a margin.

Paul Mundt 06d5631f56 sh: pfc: Verify pin type encoding size at build time.
The encoding is tightly packed, and future changes (such as
pinconf-generic support) can easily lead to a situation where we violate
the encoding constraints and trample data bit/reg bits. This plugs in
some sanity checks by way of a BUILD_BUG_ON() to blow up if we fail to
fit.

WANT_PULLUP/DOWN were never interfaced with anything, so just kill them

Paul Mundt b16b2a262c sh: pfc: Make gpio chip support optional where possible.
This implements some Kconfig knobs for ensuring that the PFC gpio chip
can be disabled or built as a module in the cases where it's optional, or
forcibly enabled in cases where it's not.

Paul Mundt b3c185a761 sh: pfc: Split out gpio chip support.
This implements a bit of rework for the PFC code, making the core itself
slightly more pluggable and moving out the gpio chip handling completely.

The API is preserved in such a way that platforms that depend on it for
early configuration are still able to do so, while making it possible to
migrate to alternate interfaces going forward.

This is the first step of chainsawing necessary to support the pinctrl
API, with the eventual goal being able to decouple pin function state
from the gpio API while retaining gpio chip tie-in for gpio pin functions
only, relying on the pinctrl/pinmux API for non-gpio function demux.

Linus Torvalds 2fe8ac608b regulator: Fixes for 3.5
One small bug fix, plus a rename of all the ST Ericsson regulators in
 the device tree since all the device trees had been written with
 different names and some infelicities in the test proceedures meant that
 the device tree code had apparently never actually been run against the
 upstream device tree.

Paul Mundt 2603efa31a bug.h: Fix up powerpc build regression.
The asm-generic/bug.h __ASSEMBLY__ guarding is completely bogus, which
tripped up the powerpc build when the kernel.h include was added:

	In file included from include/asm-generic/bug.h:5:0,
			 from arch/powerpc/include/asm/bug.h:127,
			 from arch/powerpc/kernel/head_64.S:31:
	include/linux/kernel.h:44:0: warning: "ALIGN" redefined [enabled by default]
	include/linux/linkage.h:57:0: note: this is the location of the previous definition
	include/linux/sysinfo.h: Assembler messages:
	include/linux/sysinfo.h:7: Error: Unrecognized opcode: `struct'
	include/linux/sysinfo.h:8: Error: Unrecognized opcode: `__kernel_long_t'

Moving the __ASSEMBLY__ guard up and stashing the kernel.h include under
it fixes this up, as well as covering the case the original fix was
attempting to handle.

Paul Mundt a1f42beb8e Makefile: fix up CROSS_COMPILE and READABLE_ASM interaction.
When the READABLE_ASM cc-option tests were added they were done so prior
to the arch Makefile include, resulting in cc-option being run on the
host cc instead of the factoring in the cross prefix set up by the
architecture.

This bumps the include back up so that cc-option actually runs on the
compiler that we're building with.

Matthew Garrett 7dea9665fe hfsplus: fix bless ioctl when used with hardlinks
HFS+ doesn't really implement hard links - instead, hardlinks are indicated
by a magic file type which refers to an indirect node in a hidden
directory. The spec indicates that stat() should return the inode number
of the indirect node, but it turns out that this doesn't satisfy the
firmware when it's looking for a bootloader - it wants the catalog ID of
the hardlink file instead. Fix up this case.

Linus Torvalds 41a328b95c ARM: SoC fixes
A bit larger set than usual, unfortunately -- I've been sitting on them
 longer than I meant to so it's really more like 2 -rc pull requests in
 one, volume-wise.
 
 Nearly everything is fixes for fallout from the merge window, or other
 fixes for bugs. The one exception is the highbank L2-enablement patch,
 but it was contained enough that I picked it up anyway:
 
 - i.MX fixes, mostly for clock and pinctrl changes
 - OMAP fixes, mostly PM-related
 - A patch to enable L2 on highbank
 - A couple of fixes for PXA, Kirkwood, Versatile

 "A bit larger set than usual, unfortunately -- I've been sitting on
  them longer than I meant to so it's really more like 2 -rc pull

  Nearly everything is fixes for fallout from the merge window, or other
  fixes for bugs.  The one exception is the highbank L2-enablement
  patch, but it was contained enough that I picked it up anyway:

   - i.MX fixes, mostly for clock and pinctrl changes
   - OMAP fixes, mostly PM-related
   - A patch to enable L2 on highbank
   - A couple of fixes for PXA, Kirkwood, Versatile"

Andrew Lunn 128789a829 ARM: Kirkwood: Fix clk problems modular ethernet driver
When the ethernet driver was built as a module, it would lock the
machine when loaded. At boot the ethernet clks are unused, so get
turned off.  Later, when the module is loaded, the probe function
would access the hardware before the clock was restarted, and the
machine would lock. It has also been determined that when the clk is
turned off, the interface forgets its MAC address, which for most
systems, is set by the boot loader.

When the machine setup file creates a platform device for the
interface, prepare and enable the clock for the interface. This will
ensure it is not turned off. However, if the setup file only
instantiates one platform device, the other will have its clk
disabled, thus maybe saving a little power.

Arnd Bergmann 9b0f7e3992 arm: versatile: fix and enable PCI I/O space
With commit 4d5fc58dbe (ARM: remove bunch of now unused
mach/io.h files), the I/O space setup was completely broken on
versatile. This patch fixes that and prepares for further
I/O space clean-up.

I/O space handling on the versatile platform is currently
broken in multiple ways. Most importantly, the ports do
not get mapped into the virtual address space at all.

Also, there is some amount of confusion between PCI I/O
space and other statically mapped MMIO registers in the
platform code:

* The __io_address() macro that is used to access the
  platform register maps to the same __io macro that gets
  used for I/O space.

* The IO_SPACE_LIMIT is set to a value that is much larger
  than the total available space.

* The I/O resource of the PCI bus is set to the physical
  address of the mapping, which is way outside of the
  actual I/O space limit as well as the address range that
  gets decoded by traditional PCI cards.

* No attempt is made to stay outside of the ISA port range
  that some device drivers try access.

* No resource gets requested as a child of ioport_resource,
  but an IORESOURCE_IO type mapping gets requested
  as a child of iomem_resource.

This patch attempts to correct all of the above. This makes
it possible to use virtio-pci based virtual devices as well
as actual PCI cards including those with legacy ISA port
ranges like VGA.

Some of the issues seem to be duplicated on other platforms.

Chris Metcalf 6699c8cda3 tile: fix bug in get_user() for 4-byte values
The definition of 32-bit values in the 64-bit tilegx architecture is that
they should be sign-extended regardless of whether they are considered
signed or unsigned by the compiler.  Accordingly, we need to use an
"ld4s" rather than "ld4u" to load and sign-extend for get_user().

This fixes glibc bug 14238 (see http://sourceware.org/bugzilla),
introduced during the 3.5 merge window.

Daniel Vetter 6b4e0a93ff Revert "drm/i915/dp: Use auxch precharge value of 5 everywhere"
This reverts commit 092945e11c.

This commit prevents a DP screen from properly training the link.
Oddly enough it works, once the machine has been warm-booted with an
older kernel.

According to DP docs this _should_ have been the right precharge time.
Also, the commit that originally introduces this was just general snb
DP enabling and didn't mention any specific reason for this special
value. Whatever, trust the reporter that this makes things worse and
let's just revert it.

v2: Less spelling fail.
