Pull ARM SoC bug fixes from Arnd Bergmann:
"Four patches for arm-soc this week:
- Kevin Hilman is no longer reachable under his previous email
address. He submitted the patch earlier, but nobody felt
responsible to pick it up.
- One Tegra fix for an incorect register address in device tree.
- IMX multiplatform support exposes a configuration option that leads
to unbootable kernels on all other machines and that needs to
depend on that platform.
- A nontrivial bug fix for the setup of the mxs video output."

While adding i.MX DEBUG_LL selection, commit f8c95fe (ARM: imx: support
DEBUG_LL uart port selection for all i.MX SoCs) leaves Kconfig symbol
DEBUG_IMX_UART_PORT there without any dependency check. This results in
that everyone gets the symbol in their config, which is someting
undesirable. Add "depends on ARCH_MXC" for the symbol to prevent that.

The issue fixed by this patch manifests only then using X11
with mxsfb driver. The X11 will display either shifted image
or otherwise distorted image on the LCD.
The problem is that the X11 tries to reconfigure the framebuffer
and along the way calls fb_ops.fb_set_par() with X11's desired
configuration values. The field of particular interest is
fb_info->var.sync which contains non-standard values if
configured by kernel. These are either FB_SYNC_DATA_ENABLE_HIGH_ACT,
FB_SYNC_DOTCLK_FAILING_ACT or both, depending on the platform
configuration. Both of these values are defined in the
include/linux/mxsfb.h file.
The driver interprets these values and configures the LCD controller
accordingly. Yet X11 only has access to the standard values for this
field defined in include/uapi/linux/fb.h and thus, unlike kernel,
omits these special values. This results in distorted image on the
LCD.
This patch moves these non-standard values into new field of the
mxsfb_platform_data structure so the driver can in turn check this
field instead of the video mode field for these specific portions.
Moreover, this patch prefixes these values with MXSFB_SYNC_ prefix
instead of FB_SYNC_ prefix to prevent confusion of subsequent users.

Pull ARM SoC bug fixes from Arnd Bergmann:
"Things are calming down for arm-soc as well. This set of bug fixes is
dominated in size by the at91 platform bug fixes. Some of them were
meant to go through the framebuffer tree during the merge window, but
since the framebuffer maintainer could not be reached, I offered to
take them here. The other notable at91 change is the addition of
pinctrl definitions to fix the NAND controller.
The rest are mostly simple regression fixes:
- Our removal of VIRT_TO_BUS conflicted with Stephen Rothwell's
renaming of the Kconfig symbol. You will get a trivial merge
conflict here, we still want to remove it.
- missing bits for clocks on imx and s5pv210
- missing header inclusions in mmp and shmobile
- typos in s5pv210 camera and vt8500 clock support code

- an old bogus build warning in the joystick driver

887cbce0 "arch Kconfig: centralise CONFIG_ARCH_NO_VIRT_TO_BUS"
and 4febd95a8 "Select VIRT_TO_BUS directly where needed" from
Stephen Rothwell changed globally how CONFIG_VIRT_TO_BUS is
selected, while my own a5d533ee0 "ARM: disable virt_to_bus/
virt_to_bus almost everywhere" was merged at the same time and
changed which platforms select it on ARM.
The result of this conflict was that we again see CONFIG_VIRT_TO_BUS
on all ARM systems. This patch fixes up the problem and removes
CONFIG_ARCH_NO_VIRT_TO_BUS again on ARM.

clock-event
With recent arm broadcast time clean-up from Mark Rutland, the dummy
broadcast device is always registered with timer subsystem. And since
the rating of the dummy clock event is very high, it may be preferred
over a real clock event.
This is a change in behavior from past and not an intended one. So
reduce the rating of the dummy clock-event so that real clock-event
device is selected when available.

Two small ARM i.MX fixes for v3.9-rc
- Fix i.MX25 DT compilation
- Enable MAX clk on i.MX35
* tag 'arm-imx-fixes-for-3.9-rc' of git://git.pengutronix.de/git/imx/linux-2.6:
ARM: i.MX35: enable MAX clock
ARM: i.MX25: Fix DT compilation
Signed-off-by: Arnd Bergmann <arnd@arndb.de>

The i.MX35 has two bits per clock gate which are decoded as follows:
0b00 -> clock off
0b01 -> clock is on in run mode, off in wait/doze
0b10 -> clock is on in run/wait mode, off in doze
0b11 -> clock is always on
The reset value for the MAX clock is 0b10.
The MAX clock is needed by the SoC, yet unused in the Kernel, so the
common clock framework will disable it during late init time. It will
only disable clocks though which it detects as being turned on. This
detection is made depending on the lower bit of the gate. If the reset
value has been altered by the bootloader to 0b11 the clock framework
will detect the clock as turned on, yet unused, hence it will turn it
off and the system locks up.
This patch turns the MAX clock on unconditionally making the Kernel
independent of the bootloader.

Fix regression introduced by commit d2323cf773 ("onewire: w1-gpio: add
ext_pullup_enable pin in platform data") which added a gpio entry to the
platform data, but did not add the required initialisers to the board
files using it. Consequently, the driver would request gpio 0 at probe,
which could break other uses of the corresponding pin.
On AT91 requesting gpio 0 changes the pin muxing for PIOA0, which, for
instance, breaks SPI0 on at91sam9g20.

Commit 455bd4c430b0 ("ARM: 7668/1: fix memset-related crashes caused by
recent GCC (4.7.2) optimizations") attempted to fix a compliance issue
with the memset return value. However the memset itself became broken
by that patch for misaligned pointers.
This fixes the above by branching over the entry code from the
misaligned fixup code to avoid reloading the original pointer.
Also, because the function entry alignment is wrong in the Thumb mode
compilation, that fixup code is moved to the end.
While at it, the entry instructions are slightly reworked to help dual
issue pipelines.

The ab8500 device is a child of the prcmu device, which is a memory mapped
bus device, whose children are addressable using physical memory addresses,
not using mailboxes, so a mailbox number in the ab8500 node cannot be
parsed by DT. Nothing uses this number, since it was only introduced
as part of the failed attempt to clean up prcmu mailbox handling, and
we can simply remove it.

When building a multiplatform kernel, we could end up with a smaller
number of GPIOs than the one required by the platform the kernel was
running on.
Sort the max GPIO number by descending order so that we always take the
highest number required.

Rob Herring has observed that c81611c4e96f "xen: event channel arrays are
xen_ulong_t and not unsigned long" introduced a compile failure when building
without CONFIG_AEABI:
/tmp/ccJaIZOW.s: Assembler messages:
/tmp/ccJaIZOW.s:831: Error: even register required -- `ldrexd r5,r6,[r4]'
Will Deacon pointed out that this is because OABI does not require even base
registers for 64-bit values. We can avoid this by simply using the existing
atomic64_xchg operation and the same containerof trick as used by the cmpxchg
macros. However since this code is used on memory which is shared with the
hypervisor we require proper atomic instructions and cannot use the generic
atomic64 callbacks (which are based on spinlocks), therefore add a dependency
on !GENERIC_ATOMIC64. Since we already depend on !CPU_V6 there isn't much
downside to this.
While thinking about this we also observed that OABI has different struct
alignment requirements to EABI, which is a problem for hypercall argument
structs which are shared with the hypervisor and which must be in EABI layout.
Since I don't expect people to want to run OABI kernels on Xen depend on
CONFIG_AEABI explicitly too (although it also happens to be enforced by the
!GENERIC_ATOMIC64 requirement too).

We always boot from PLL1, so let's have pll1_sys in the clks_init_on
list to have clk prepare/enable use count match the hardware status,
so that drivers managing pll1_sys like cpufreq can get the use count
right from the start.

There is no need to have a #address-cells property in the MPIC Device
Tree node, and more than that, having it confuses the of_irq_map_raw()

During the system initialization, the orion_setup_cpu_mbus_target()
function reads the SDRAM address decoding registers to find out how
many chip-selects of SDRAM have been enabled, and builds a small array
with one entry per chip-select. This array is then used by device
drivers (XOR, Ethernet, etc.) to configure their own address decoding
windows to the SDRAM.
However, devices can only access the first 32 bits of the physical
memory. Even though LPAE is not supported for now, some Marvell boards
are now showing up with 8 GB of RAM, configured using two SDRAM
address decoding windows: the first covering the first 4 GB, the
second covering the last 4 GB. The array built by
orion_setup_cpu_mbus_target() has therefore two entries, and device
drivers try to set up two address decoding windows to the
SDRAM. However, in the device registers for the address decoding, the
base address is only 32 bits, so those two windows overlap each other,
and the devices do not work at all.
This patch makes sure that the array built by
orion_setup_cpu_mbus_target() only contains the SDRAM decoding windows
that correspond to the first 4 GB of the memory. To do that, it
ignores the SDRAM decoding windows for which the 4 low-order bits are
not zero (the 4 low-order bits of the base register are used to store
bits 32:35 of the base address, so they actually indicate whether the
base address is above 4 GB).
This patch allows the newly introduced armada-xp-gp board to properly
operate when it is mounted with more than 4 GB of RAM. Without that,
all devices doing DMA (for example XOR and Ethernet) do not work at
all.

Setting the reg-io-width to 1 byte represents more accurate
description of the HW.
This will fix an issue where UART driver causes kernel
panic during bootup. Gregory CLEMENT traced the issue to
autoconfig() in 8250.c, where the existence of FIFO is
checked from UART_IIR register. The register is now read as
32-bit value as the reg-io-width is set to 4-bytes. The
retuned value seems to contain bogus data for bits 31:8,
causing the issue.
