The spear/pinctrl branch has hard dependencies on both the
pinctrl branch and the clkdev branch. We merge those here
to fix it up without having to rebase a branch that has
been pulled into other stable branches already.

Create a struct clk_init_data to hold all data that needs to be passed from
the platfrom specific driver to the common clock framework during clock
registration. Add a pointer to this struct inside clk_hw.
This has several advantages:
* Completely hides struct clk from many clock platform drivers and static
clock initialization code that don't care for static initialization of
the struct clks.
* For platforms that want to do complete static initialization, it removed
the need to directly mess with the struct clk's fields while still
allowing to statically allocate struct clk. This keeps the code more
future proof even if they include clk-private.h.
* Simplifies the generic clk_register() function and allows adding optional
fields in the future without modifying the function signature.
* Simplifies the static initialization of clocks on all platforms by
removing the need for forward delcarations or convoluted macros.

Besides the static initialization, the clk_ops of basic clks could
also be used by particular clk type being subclass of the basic clks.
For example, clk_busy_divider has the same clk_ops as clk_divider,
except it has to wait for a busy bit before return success with
.set_rate. clk_busy_divider will somehow reuse clk_ops of clk_divider.
Since clk-provider.h is included by clk-private.h, it's safe to move
those clk_ops declaration of basic clks form clk-private.h into
clk-provider.h, so that implementation of clks like clk_busy_divider
above do not need to include clk-private.h to access those clk_ops.

This continues the theme started with vm_brk() and vm_munmap():
vm_mmap() does the same thing as do_mmap(), but additionally does the
required VM locking.
This uninlines (and rewrites it to be clearer) do_mmap(), which sadly
duplicates it in mm/mmap.c and mm/nommu.c. But that way we don't have
to export our internal do_mmap_pgoff() function.
Some day we hopefully don't have to export do_mmap() either, if all
modular users can become the simpler vm_mmap() instead. We're actually
very close to that already, with the notable exception of the (broken)
use in i810, and a couple of stragglers in binfmt_elf.

Most of the SoC drivers implement list_groups() and list_functions()
routines for pinctrl and pinmux. These routines continue returning
zero until the selector argument is greater than total count of
available groups or functions.
This patch replaces these list_*() routines with get_*_count()
routines, which returns the number of available selection for SoC
driver. pinctrl layer will use this value to check the range it can
choose.
This patch fixes all user drivers for this change. There are other
routines in user drivers, which have checks to check validity of
selector passed to them. It is also no more required and hence
removed.

Here are the fixes I have queued for v3.4-rc cycle so far.
It includes fixes on many of the gadget drivers and a few
of the UDC controller drivers.
For musb we have a fix for a kernel oops when unloading
omap2430.ko glue layer, proper error checking for pm_runtime_*,
fix for the ULPI transfer block, and a bug fix in musb_cleanup_urb
routine.
For s3c-hsotg we have mostly FIFO-related fixes (proper TX FIFO
allocation, TX FIFO corruption fix in DMA mode) but also a couple
of minor fixes (fixing maximum packet size for ep0 and fix for
big transfers with DMA).
For the dwc3 driver we have a memory leak fix, a very important
fix for USB30CV with SetFeature tests and the hability to handle
ep0 requests bigger than wMaxPacketSize.
On top of that there's a bunch of gadget driver minor fixes adding
proper section annotations, and fixing up the sysfs interface for
doing device-initiated connect/disconnect and so on.
All patches have been pending on the mailing list for quite a while
and look good for your for-linus branch.

usb: fixes for v3.4-rc cycle
Here are the fixes I have queued for v3.4-rc cycle so far.
It includes fixes on many of the gadget drivers and a few
of the UDC controller drivers.
For musb we have a fix for a kernel oops when unloading
omap2430.ko glue layer, proper error checking for pm_runtime_*,
fix for the ULPI transfer block, and a bug fix in musb_cleanup_urb
routine.
For s3c-hsotg we have mostly FIFO-related fixes (proper TX FIFO
allocation, TX FIFO corruption fix in DMA mode) but also a couple
of minor fixes (fixing maximum packet size for ep0 and fix for
big transfers with DMA).
For the dwc3 driver we have a memory leak fix, a very important
fix for USB30CV with SetFeature tests and the hability to handle
ep0 requests bigger than wMaxPacketSize.
On top of that there's a bunch of gadget driver minor fixes adding
proper section annotations, and fixing up the sysfs interface for
doing device-initiated connect/disconnect and so on.
All patches have been pending on the mailing list for quite a while
and look good for your for-linus branch.
Complete the separation of the twl6040 from the twl core since
it is a separate chip, not part of the twl6030 PMIC.
Make the needed Kconfig changes for the depending drivers at the
same time to avoid breaking the kernel build (vibra, ASoC components).

The ux500 default config enables the db5500 and the db8500.
The incoming cpuidle driver uses the 'prcmu_enable_wakeups'
and the 'prcmu_set_power_state' functions but these ones
are defined but not implemented for the db5500, leading to
an unresolved symbol error at link time. In order to compile,
we have to disable the db5500 support which is not acceptable
for the default config.
I noticed there are also some other functions which are
defined but not implemented.
This patch fix this by removing the functions definitions
and move out of the config section the empty functions which
are normally used when the DB550 config is disabled.
Only the functions which are not implemented are concerned
by this modification.

Pull ARM fixes from Russell King:
"Nothing too disasterous, the biggest thing being the removal of the
regulator support for vcore in the AMBA driver; only one SoC was using
this and it got broken during the last merge window, which then
started causing problems for other people. Mutual agreement was
reached for it to be removed."

Commit 18a4d0a22e ("[SCSI] Handle disk devices which can not process
medium access commands") introduced a bug in which we would attempt to
dereference the scsi driver even when the device had no ULD attached.
Ensure that a driver is registered and make the driver accessor function
more resilient to errors during device discovery.

GCC's NULL is actually __null, which allows detecting some questionable
NULL usage and warn about it. Moreover each platform/compiler should
have its own stddef.h anyway (which is different from linux/stddef.h).
So there's no good reason to leak kernel's NULL to userspace and
override what the compiler provides.
