Daniel Walker efdfb2b118 msm: fix Kconfig target board selection
This prevents build failures since it's currently possible to select
8x50, 7x30, or 7x00 without selecting a specific board. These changes
just force a target selection, which is currently defaulting to the most
common one (7x30 only has one).

Daniel Walker 79d98313e0 msm: fix compile failure on struct membank node member
In commit be37030274
"ARM: Remove DISCONTIGMEM support", it removed this "node" member
which cased the following compile failure in mach-msm,

linux/arch/arm/mach-msm/board-halibut.c: In function 'halibut_fixup':
linux/arch/arm/mach-msm/board-halibut.c:86: error: 'struct membank' has no member named 'node'
linux/arch/arm/mach-msm/board-halibut.c:86: error: implicit declaration of function 'PHYS_TO_NID'

I've removed the access to the node member which corrects the
compile failure.

Nicolas Pitre 6451d7783b arm: remove machine_desc.io_pg_offst and .phys_io
Since we're now using addruart to establish the debug mapping, we can
remove the io_pg_offst and phys_io members of struct machine_desc.

The various declarations were removed using the following script:

  grep -rl MACHINE_START arch/arm | xargs \
  sed -i '/MACHINE_START/,/MACHINE_END/ { /\.\(phys_io\|io_pg_offst\)/d }'

[ Initial patch was from Jeremy Kerr, example script from Russell King ]

Jeremy Kerr 0ea1293009 arm: return both physical and virtual addresses from addruart
Rather than checking the MMU status in every instance of addruart, do it
once in kernel/debug.S, and change the existing addruart macros to
return both physical and virtual addresses. The main debug code can then
select the appropriate address to use.

This will also allow us to retreive the address of a uart for the MMU
state that we're not current in.

Arnd Bergmann 6038f373a3 llseek: automatically add .llseek fop
All file_operations should get a .llseek operation so we can make
nonseekable_open the default for future file operations without a
.llseek pointer.

The three cases that we can automatically detect are no_llseek, seq_lseek
and default_llseek. For cases where we can we can automatically prove that
the file offset is always ignored, we use noop_llseek, which maintains
the current behavior of not returning an error from a seek.

New drivers should normally not use noop_llseek but instead use no_llseek
and call nonseekable_open at open time.  Existing drivers can be converted
to do the same when the maintainer knows for certain that no user code
relies on calling seek on the device file.

The generated code is often incorrectly indented and right now contains
comments that clarify for each added line why a specific variant was
chosen. In the version that gets submitted upstream, the comments will
be gone and I will manually fix the indentation, because there does not
seem to be a way to do that using coccinelle.

Some amount of new code is currently sitting in linux-next that should get
the same modifications, which I will do at the end of the merge window.

Many thanks to Julia Lawall for helping me learn to write a semantic
patch that does all this.

Gregory Bean 1963a2afc8 msm: add gpiomux api for gpio multiplex & configuration.
Add the 'gpiomux' api, which addresses the following shortcomings
of existing tlmm api:

- gpio power-collapse, which is managed by a peripheral processor on
  other targets, must be managed by the application processor on the 8x60.
- The enable/disable flag of the legacy gpio_tlmm_config api
  is not applicable on the 8x60, and causes confusion.
- The gpio 'direction' bits are meaningless for all func_sel
  configurations except for generic-gpio mode (func_sel 0), in which
  case the gpio_direction_* functions should be used.  Having these
  bits in the tlmm api leads to confusion and misuse of the gpiolib
  api, and they have been removed in gpiomux.
- The functional api of the legacy system ran contrary to the typical
  use-case, which is a single massive configuration at boot.  Rather
  than forcing hundreds of 'config' function calls, the new api
  allows data to be configured with a single table.

gpiomux_get and gpiomux_put are meant to be called automatically
when gpio_request and gpio_free are called, giving automatic
gpiomux/tlmm control to those drivers/lines with simple
power profiles - in the simplest cases, an entry in the gpiomux table
and the correct usage of gpiolib is all that is required to get proper
gpio power control.

Nicolas Pitre 7c63984b86 ARM: do not define VMALLOC_END relative to PAGE_OFFSET
VMALLOC_END is supposed to be an absolute value, while PAGE_OFFSET may
vary depending on the selected user:kernel memory split mode through
CONFIG_VMSPLIT_*.  In fact, the goal of moving PAGE_OFFSET down is to
accommodate more directly addressed RAM by the kernel below the vmalloc
area, and having VMALLOC_END move along PAGE_OFFSET is rather against
the very reason why PAGE_OFFSET can be moved in the first place.

Daniel Walker bf83de4037 arm: msm: smd: use either package v3 or v4 not both
This modifies SMD to use either the package v3 or package v4,
but not both. The current code tries to allocate as v4 on all
system which can produce a scary looking error message on boot up,

smem_find(16, 40): wrong size 16424
smd_alloc_channel() cid=02 size=08192 'SMD_RPCCALL'

With this error the code then falls back on the package v3 allocation
method. This method is inefficient because it causes a slow down
on some systems even when the allocation method can be determined
at compile time. It also causes a kernel size increase that effects
all system and is not needed.

This change corrects the allocation to use one method or the other
and not both.

San Mehat 5b00f40f90 msm: Add 'execute' datamover callback
Based on a patch from Brent DeGraaf:

"The datamover supports channels which can be shared amongst devices.
As a result, the actual data transfer may occur some time after the
request is queued up. Some devices such as mmc host controllers
will timeout if a command is issued too far in advance of the actual
transfer, so if dma to other devices on the same channel is already
in progress or queued up, the added delay can cause pending transfers
to fail before they start. This change extends the api to allow a
user callback to be invoked just before the actual transfer takes
place, thus allowing actions directly associated with the dma
transfer, such as device commands, to be invoked with precise timing.
Without this mechanism, there is no way for a driver to realize
this timing. Also adds a user pointer to the command structure for use
by the caller to reference information that may be needed by the
callback routine for proper identification and processing associated
with that specific request. This change is necessary to fix problems
associated with excessive command timeouts and race conditions in the
mmc driver."

This patch also fixes all the callers of msm_dmov_enqueue_cmd() to
ensure their callback function is NULL.

Russell King be093beb60 [ARM] pass reboot command line to arch_reset()
OMAP wishes to pass state to the boot loader upon reboot in order to
instruct it whether to wait for USB-based reflashing or not.  There is
already a facility to do this via the reboot() syscall, except we ignore
the string passed to machine_restart().

This patch fixes things to pass this string to arch_reset().  This means
that we keep the reboot mode limited to telling the kernel _how_ to
perform the reboot which should be independent of what we request the
boot loader to do.

Rusty Russell 320ab2b0b1 cpumask: convert struct clock_event_device to cpumask pointers.
Impact: change calling convention of existing clock_event APIs

struct clock_event_timer's cpumask field gets changed to take pointer,
as does the ->broadcast function.

Another single-patch change.  For safety, we BUG_ON() in
clockevents_register_device() if it's not set.

As Al did for Versatile in 2ad4f86b60,
add a typesafe __io implementation for platforms to use.  Convert
platforms to use this new simple typesafe implementation.

Nicolas Pitre b5ee900258 [ARM] remove a common set of __virt_to_bus definitions
Let's provide an overridable default instead of having every machine
class define __virt_to_bus and __bus_to_virt to the same thing.  What
most platforms are using is bus_addr == phys_addr so such is the default.

One exception is ebsa110 which has no DMA what so ever, so the actual
definition is not important except only for proper compilation.  Also
added a comment about the special footbridge bus translation.

Let's also remove comments alluding to set_dma_addr which is not
(and should not) be commonly used.

Brian Swetland f030d7b65e [ARM] msm: vreg interface to msm7k pmic
The baseband cpu owns the pmic, so voltage regulator control is only
available via a relatively limited interface through the proc_comm
transport.

San:
- Propagate DM errors to the originator of the request.
- Implement msm_dmov_stop_cmd()
- Add return value to init code
- Modify msm_dmov_stop_cmd() to support ungraceful flushing

Arve:
- Disable datamover interrupt when not in use.
  We turn off the interrrupt to allow power collapse from idle.

Brian Swetland bcc0f6af07 [ARM] msm: clean up iomap and devices
- Add some more peripherals (sdcc, etc) to the iomap.
- Remove virtual base addresses for devices that we should be passing
  physical addresses to drivers via resources and ioremap()ing.
- don't try to use uarts for ll debug once the mmu is enabled due to
  problems with the peripheral window
- make base addresses void __iomem * and fixup irq.c and timer.c
- Remove common.c and bring in devices.c/devices.h similar to
  the PXA architecture.

Brian Swetland b8a16e1fdf [ARM] msm: add proc_comm support, necessary for clock and power control
The proc_comm protocol is the lowest level protocol available for
communicating with the modem core.  It provides access to clock and
power control, among other things, and is safe for use from atomic
contexts, unlike the higher level SMD and RPC transports.

Brian Swetland 1637de0c9b [ARM] msm: rename ARCH_MSM7X00A to ARCH_MSM
The MSM architecture covers a wider family of chips than just the MSM7X00A.
Move to a more generic name, in perparation for supporting the specific
SoC variants as sub-architectures (ARCH_MSM7X01A, ARCH_MSM722X, etc).  This
gives us ARCH_MSM for the (many) common peripherals.

This also removes the unused/obsolete config item MSM7X00A_IDLE.
