f604931238 ARM: OMAP: abstract debug card setup (smc, leds)
Additional cleanup for debug boards on H2/P2/H3/H4:  move the init
code that's not board-specific into a new file where it can be easily
shared between all the different boards (avoiding code duplication,
and making it easier to support more devices).  Make H4 use that.

This should be easy to drop in to the OMAP1 boards using these debug
cards; the only difference seems to be that the p2 does an extra reset
of the smc using the fpga (probably all boards could do that, if it's
necessary) and doesn't use the gpio mux or request APIs.

1c22cc1325 ARM: OMAP: omap2/gpmc updates
GPMC updates:
 - bugfixes: wrong/missing flags, omitted write, wrong test
 - don't map memory segments starting at zero
 - improve debug messaging
 - export gpmc_get_fclk_perio]d() since it's needed to calc timings
 - expect gpmc_cs_set_timings() caller to have initialized sync vs async

Note that this API is glitchy; likely the best fix would be to add
a member to "struct gpmc_timings" to hold GPMC_CONFIG1, since that
holds one key aspect of the GPMC timings (the gpmc_fclk divisor,
and sync vs. async == whether that divisor matters).

03e5386e1e [ARM] 4530/1: MXC: fix elf_hwcap compile breakage as in iop13xx
MXC needs the same change as IOP.  See [ARM] 4494/1
or commit 7dea1b2006

An undefined reference to elf_hwcap prevents linkage, due
to changes made by f884b1cf57
and d1cbbd6b41

Removing processor.h removes the extern definition of
elf_hwcap, which fixes the link issue, but forgets cpu_relax().
So, instead, we'll call barrier() directly.

These patches add full SSP/MCU support for the HP Jornada 720
machine.  Its needed to handle keyboard, touchscreen, battery
and backlight/lcd.

The main driver exports functions and the header file exports
the command values. When talking to the MCU the general procedure
is to start MCU, send command (using ssp_inout(command)), the
proper reply is always TXDUMMY.  After receiving TXDUMMY you can
send the value you wish pushed (for example brightness level).
End with ssp_end() so the spinlock gets unlocked.

Drivers using this havent been implemented yet, but will shortly.

b750a09385 [ARM] 4489/1: pxa: split pxa_cpu_suspend to processor specific ones
1. split pxa_cpu_suspend to pxa25x_cpu_suspend and pxa27x_cpu_suspend
   and make pxa25x_cpu_pm_enter() and pxa27x_cpu_pm_enter() to invoke
   the corresponding _suspend functions, thus remove all those ugly
   #ifdef .. #endif out of sleep.S

2. move the declarations of those suspend functions to pm.h

note: this is not a clean enough solution until all the pxa25x and
pxa27x specific part is further removed out of sleep.S, sleep.S is
supposed to contain generic code only

711be5ccfe [ARM] 4488/1: pxa: move pxa25x/pxa27x specific code out of pm.c
1. introduce a structure pxa_cpu_pm_fns for pxa25x/pxa27x specific
   operations as follows:

	struct pxa_cpu_pm_fns {
		int	save_size;
		void	(*save)(unsigned long *);
		void	(*restore)(unsigned long *);
		int	(*valid)(suspend_state_t state);
		void	(*enter)(suspend_state_t state);
	}

2. processor specific registers saving and restoring are performed
   by calling the corresponding (*save) and (*restore)

3. pxa_cpu_pm_fns->save_size should be initialized to the required
   size for processor specific registers saving, the allocated
   memory address will be passed to (*save) and (*restore)

   memory allocation happens early in pxa_pm_init(), and save_size
   should be assigned prior to this (which is usually true, since
   pxa_pm_init() happens in device_initcall()

4. there're some redundancies for those SLEEP_SAVE_XXX and related
   macros, will be fixed later, one way possible is for the system
   devices to handle the specific registers saving and restoring

70c14ff0e9 [ARM] 4495/1: iop: combined watchdog timer driver for iop3xx and iop13xx
In order for this driver to be shared across the iop architectures the
iop3xx and iop13xx header files are modified to present a common interface
for the iop_wdt driver.

Details:
* iop13xx supports disabling the timer while iop3xx does not.  This requires
  a few 'compatibility' definitions in include/asm-arm/hardware/iop3xx.h to
  preclude adding #ifdef CONFIG_ARCH_IOP13XX blocks to the driver code.
* The heartbeat interval is derived from the internal bus clock rate, so this
  this patch also exports the tick rate to the iop_wdt driver.

arch/arm/boot/compressed/misc.o: In function `valid_user_regs':
misc.c:(.text+0x74): undefined reference to `elf_hwcap'

This triggers after the various elf_hwcap cleanups in:
f884b1cf57
d1cbbd6b41

include/asm-arm/arch-iop13xx/uncompress.h calls cpu_relax while spinning on
a register value.  cpu_relax requires processor.h->ptrace.h->hwcap.h

'elf_hwcap' is defined as an extern, but since the uncompressor does not
link against arch/arm/kernel/setup.c 'elf_hwcap' remains undefined.

Fix is to open code the cpu_relax() call as barrier().

c211092313 dmaengine: driver for the iop32x, iop33x, and iop13xx raid engines
The Intel(R) IOP series of i/o processors integrate an Xscale core with
raid acceleration engines.  The capabilities per platform are:

iop219:
 (2) copy engines
iop321:
 (2) copy engines
 (1) xor and block fill engine
iop33x:
 (2) copy and crc32c engines
 (1) xor, xor zero sum, pq, pq zero sum, and block fill engine
iop34x (iop13xx):
 (2) copy, crc32c, xor, xor zero sum, and block fill engines
 (1) copy, crc32c, xor, xor zero sum, pq, pq zero sum, and block fill engine

The driver supports the features of the async_tx api:
* asynchronous notification of operation completion
* implicit (interupt triggered) handling of inter-channel transaction
  dependencies

The driver adapts to the platform it is running by two methods.
1/ #include <asm/arch/adma.h> which defines the hardware specific
   iop_chan_* and iop_desc_* routines as a series of static inline
   functions
2/ The private platform data attached to the platform_device defines the
   capabilities of the channels

20070626: Callbacks are run in a tasklet.  Given the recent discussion on
LKML about killing tasklets in favor of workqueues I did a quick conversion
of the driver.  Raid5 resync performance dropped from 50MB/s to 30MB/s, so
the tasklet implementation remains until a generic softirq interface is
available.

Changelog:
* fixed a slot allocation bug in do_iop13xx_adma_xor that caused too few
slots to be requested eventually leading to data corruption
* enabled the slot allocation routine to attempt to free slots before
returning -ENOMEM
* switched the cleanup routine to solely use the software chain and the
status register to determine if a descriptor is complete.  This is
necessary to support other IOP engines that do not have status writeback
capability
* make the driver iop generic
* modified the allocation routines to understand allocating a group of
slots for a single operation
* added a null xor initialization operation for the xor only channel on
iop3xx
* support xor operations on buffers larger than the hardware maximum
* split the do_* routines into separate prep, src/dest set, submit stages
* added async_tx support (dependent operations initiation at cleanup time)
* simplified group handling
* added interrupt support (callbacks via tasklets)
* brought the pending depth inline with ioat (i.e. 4 descriptors)
* drop dma mapping methods, suggested by Chris Leech
* don't use inline in C files, Adrian Bunk
* remove static tasklet declarations
* make iop_adma_alloc_slots easier to read and remove chances for a
  corrupted descriptor chain
* fix locking bug in iop_adma_alloc_chan_resources, Benjamin Herrenschmidt
* convert capabilities over to dma_cap_mask_t
* fixup sparse warnings
* add descriptor flush before iop_chan_enable
* checkpatch.pl fixes
* gpl v2 only correction
* move set_src, set_dest, submit to async_tx methods
* move group_list and phys to async_tx

d1cbbd6b41 [ARM] 4474/1: Do not check the PSR_F_BIT in valid_user_regs
When running Linux in non-secure mode (on ARM1176 for example),
depending on the CP15 secure configuration register, the CPSR.F bit
(6) might only be modified from the secure mode. However, the
valid_user_regs() function checks for this bit being cleared. With
commit a6c61e9d, a SIGSEGV is forced in handle_signal() if the user
registers are not considered valid.

The patch also ensures that the CPSR.A bit is cleared and the USR mode
is set if the CPU does not support the 26bit user mode.

f53f066c25 [ARM] 4451/1: pxa: make dma.c generic and remove cpu specific dma code
Since the number of dma channels varies between pxa25x and pxa27x, it
introduces some specific code in dma.c. This patch moves the specific
code to pxa25x.c and pxa27x.c and makes dma.c more generic.

1. add pxa_init_dma() for dma initialization, the number of channels
   are passed in by the argument

2. add a "prio" field to the "struct pxa_dma_channel" for the channel
   priority, and is initialized in pxa_init_dma()

3. use a general priority comparison with the channels "prio" field so
   to remove the processor specific pxa_for_each_dma_prio macro,  this
   is not lightning fast as the original one,  but it is acceptable as
   it happens when requesting dma, which is usually not so performance
   critical

486c955118 [ARM] 4434/1: PXA: remove PXA_IRQ_SKIP
1. PXA_IRQ_SKIP is defined to be 7 on PXA25x so that the first IRQ
   starts from zero. This makes IRQ numbering inconsistent between
   PXA25x and PXA27x. Remove this macro so that the same IRQ_XXXXX
   definition has the same value on both PXA25x and PXA27x.

2. make IRQ_SSP3..IRQ_PWRI2C valid only if PXA27x is defined, this
   avoids unintentional use of these macros on PXA25x

f62c3f2c35 [ARM] pxa: remove useless pxa_pm_finish() function
pxa_pm_finish() does nothing but return zero.  The core code
does nothing with this return value, and will not try to call
the finish method in the pm_ops structure if it is NULL.

Therefore, we can remove this useless function.

Support for generic input output for MX1 family.
The implementation prevents allocation of one pin
by two users, but does not store pointer to the user
description permanently, because this solution
would have bigger memory overhead.

The simple way to integrate code with per BSP
pins setup and allocation is required else all GPIO
registration checking is useless. The function
imx_gpio_setup_multiple_pins() can be used for this
purpose in future.

I'm not sure if this is going to fly, weak symbols work on the compilers I'm
using, but whether they work for all of the affected architectures I can't say.
I've cc'ed as many arch maintainers/lists as I could find.

But assuming they do, we can use a weak empty definition of
pcibios_add_platform_entries() to avoid having an empty definition on every
arch.

edd5cd4a94 Introduce fixed sys_sync_file_range2() syscall, implement on PowerPC and ARM
Not all the world is an i386.  Many architectures need 64-bit arguments to be
aligned in suitable pairs of registers, and the original
sys_sync_file_range(int, loff_t, loff_t, int) was therefore wasting an
argument register for padding after the first integer.  Since we don't
normally have more than 6 arguments for system calls, that left no room for
the final argument on some architectures.

Fix this by introducing sys_sync_file_range2(int, int, loff_t, loff_t) which
all fits nicely.  In fact, ARM already had that, but called it
sys_arm_sync_file_range.  Move it to fs/sync.c and rename it, then implement
the needed compatibility routine.  And stop the missing syscall check from
bitching about the absence of sys_sync_file_range() if we've implemented
sys_sync_file_range2() instead.

Tested on PPC32 and with 32-bit and 64-bit userspace on PPC64.
