The new reset controller API is optional, so if that is disabled,
we must not call it from platform code.

device_register() returns -ve values for errors, and zero for success.
There's no need to obfuscate the code with IS_ERR_VALUE().

More multiplatform enablement for ARM platforms. The ones converted in
this branch are:
- bcm2835
- cns3xxx
- sirf
- nomadik
- msx
- spear
- tegra
- ux500
We're getting close to having most of them converted!
One of the larger platforms remaining is Samsung Exynos, and there are
a bunch of supporting patches in this merge window for it. There was a
patch in this branch to a early version of multiplatform conversion,
but it ended up being reverted due to need of more bake time. The
revert commit is part of the branch since it would have required
rebasing multiple dependent branches and they were stable by then.

Device-tree updates for 3.10. The bulk of the churn in this branch is due
to i.MX moving from C-defined pin control over to device tree, which is
a one-time conversion that will allow greater flexibility down the road.
Besides that, there's PCI-e bindings for Marvell mvebu platforms and a
handful of cleanups to tegra due to the new include file functionality
of the device tree compiler.

Here is a collection of fixes (and some intermixed cleanups) that were
considered less important and thus not included in the later parts of
the 3.9-rc cycle.
It's a bit all over the map, contents wise. A series of ux500 fixes
and cleanups, a bunch of various fixes for OMAP and tegra, and some for
Freescale i.MX and even Qualcomm MSM.
Note that there's also a patch on this branch to globally turn off
-Wmaybe-uninitialized when building with -Os. It's been posted several
times by Arnd and no dissent was raised, but nobody seemed interested
to pick it up. So here it is, as the topmost patch.

The code intializes the cpuidle driver at different places.
The cpuidle driver for :

* imx6 : is in cpuidle-imx6q.c, the init function is in cpuidle.c
and cpuidle-imx6q.c
Instead of having the cpuidle code spread across different files,
let's create a driver for each SoC and use the common register function.

The i.MX6 Quad can be fused as i.MX6 Dual chip, and similarly i.MX6
DualLite can be fused as i.MX6 Solo. The actual number of available
cores can be found out from SCU.
Since we do not reflect the fusing thing in device tree, the function
arm_dt_init_cpu_maps() will always call set_cpu_possible(true) for 4
cores on i.MX6 Quad/Dual and 2 cores for i.MX6 DualLite/Solo. This
causes failures when kernel tries to bring those unavailable cores
online. For example, the following failure message will be seen when
booting an i.MX6 Solo chip.
CPU1: failed to come online
Though kernel will still boot fine, the message is somehow annoying.
Let's get rid of it by calling set_cpu_possible(false) on those
unavailable cores.
While at it, the set_cpu_possible(true) for available cores is removed,
since it's already been done in arm_dt_init_cpu_maps().

Function imx_anatop_get_digprog() that reads register ANADIG_DIGPROG is
called to identify silicon version. Users might query silicon version
earlier than regmap subsystem is ready. For example, imx6q clock driver
query revision in mx6q_clocks_init(), where regmap is not initialized

RBC is to control whether some ANATOP sub modules
can enter lpm mode when SOC is into STOP mode, if
RBC is enabled and PMIC_VSTBY_REQ is set, ANATOP
will have below behaviors:
1. Digital LDOs(CORE, SOC and PU) are bypassed;
2. Analog LDOs(1P1, 2P5, 3P0) are disabled;
As the 2P5 is necessary for DRAM IO pre-drive in
STOP mode, so we need to enable weak 2P5 in STOP
mode when 2P5 LDO is disabled.
For RBC settings, there are some rules as below
due to hardware design:
1. All interrupts must be masked during operating
RBC registers;
2. At least 2 CKIL(32K) cycles is needed after the
RBC setting is changed.

The TWD and SCU configs are selected by default as long as
MSM_SCORPIONMP is false and/or MCT is false. Implementing the
logic this way certainly saves lines in the Kconfig but it
precludes those machines which select MSM_SCORPIONMP or MCT from
participating in the single zImage effort because when those
machines are combined with other SMP capable machines the TWD and
SCU are no longer selected by default.
Push the select out to the machine entries so that we can compile
these machines together and still select the appropriate configs.

This patch enables iomuxc_gate clock. It is necessary to be able to
reconfigure iomux pads. Without this clock enabled, the
clk_disable_unused function will disable this clock and the iomux pads
are not configurable anymore. This happens at every boot. After a reboot
(watchdog system reset) the clock is not enabled again, so all iomux pad
reconfigurations in boot code are without effect.
The iomux pads should be always configurable, so this patch always
enables it.

- per: peripheral clock, the clock needed for generating the bit rate.
Currently ssi driver only supports slave mode and thus need only to handle

There is a sync issue with hotplug operation. It's possible that when
imx_cpu_kill gets running on primary core, the imx_cpu_die execution
on the core which is to be killed hasn't been finished yet. The problem
will very likely be hit when running suspend without no_console_suspend
setting on kernel cmdline.
It uses cpu jumping argument register to sync imx_cpu_die and
imx_cpu_kill. The register will be set in imx_cpu_die and imx_cpu_kill
will wait for the register being cleared to actually kill the cpu.

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.

Building the kernel with allyesconfig fails because the i.mx early
resume code located in the .data section is unable to fixup the bl
relocation as the branch target gets too far away.
The idea of having code in the .data section allows for easy access to
nearby data using relative addressing while the MMU is off. However it
is probably best to move the code back to the .text section where it
belongs and fixup the data access instead. This solves the bl reloc
issue (at least until this becomes a general problem) and simplifies
the code as well.

This branch contains of devicetree changes for the Freescale i.MX platform.
The base patch of the branch changes the format of the dts files to a
slightly different format that makes it easier to do derivative board
definitions, but it also introduces a lot of churn in the process since
every line of the file is touched.
On top of that are a handful of the regular changes; enabling more boards
as DT-based instead of legacy board files (mx25pdk), enabling another
driver for devicetree and thus adding bindings (onewire), etc.
I'm not happy about the churn, and will likely not take it for other platforms
in the future.

A large number of cleanups, all over the platforms. This is dominated
largely by the Samsung platforms (s3c, s5p, exynos) and a few of the
others moving code out of arch/arm into more appropriate subsystems.
The clocksource and irqchip drivers are now abstracted to the point
where platforms that are already cleaned up do not need to even specify
the driver they use, it can all get configured from the device tree
as we do for normal device drivers. The clocksource changes basically
touch every single platform in the process.
We further clean up the use of platform specific header files here,
with the goal of turning more of the platforms over to being
"multiplatform" enabled, which implies that they cannot expose
their headers to architecture independent code any more.
It is expected that no functional changes are part of the cleanup.
The overall reduction in total code lines is mostly the result of
removing broken and obsolete code.

Their parents are dummy clock, we only needs to enable
it after system boots up.
- usbphy1 and usbphy2

The mxc-timer on the imx25 needs to be derived from the AHB clock.
If a bootloader reparents this clock to the ipg_clk_highfreq, which according
to the datasheet is a valid operation, the system can/will produce lockups/
freezes after some time [1].
This can be forced with code like
while(1)
syscall(SYS_clock_gettime, CLOCK_REALTIME, &tp);
This was already fixed with the commit
"i.MX25 GPT clock fix: ensure correct the clock source" [2],
for 3.1-rc2, but was lost, when i.MX was converted to the common clock framework
("ARM i.MX25: implement clocks using common clock framework") [3]

Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
The return of v2_set_next_event() will lead to an infinite loop in
tick_handle_oneshot_broadcast() - "goto again;" with imx6q WAIT mode
(to be enabled). This happens because when global event did not expire
any CPU local events, the broadcast device will be rearmed to a CPU
local next_event, which could be far away from now and result in a
max_delta_tick programming in set_next_event().
Fix the problem by detecting those next events with increments larger
than 0x7fffffff, and simply return zero in that case.
It leaves mx1_2_set_next_event() unchanged since only v2_set_next_event()
will be running with imx6q WAIT mode support.
Thanks Russell King for helping understand the problem.

- Header file move for a driver that hadn't been properly converted to

- Device tree updates for at91 dealing mostly with their new

Pull ARM SoC fixes from Olof Johansson:
"Here's a long-pending fixes pull request for arm-soc (I didn't send
one in the -rc4 cycle).
The larger deltas are from:
- A fixup of error paths in the mvsdio driver
- Header file move for a driver that hadn't been properly converted
to multiplatform on i.MX, which was causing build failures when
included
- Device tree updates for at91 dealing mostly with their new pinctrl
setup merged in 3.8 and mistakes in those initial configs
The rest are the normal mix of small fixes all over the place; sunxi,
omap, imx, mvebu, etc, etc."

The hardware reset value of bit CCM_CLPCR_LPM enables WAIT mode
(WAIT_UNCLOCKED) by default. However this is undesirable because
WAIT mode should only be enabled when there is a driver managing
ARM clock gating. Correct the initial power mode to WAIT_CLOCKED
(disable WAIT mode). While at it, the power mode after resuming
is also set back to WAIT_CLOCKED from STOP_POWER_OFF.

It's buggy to disable the cpu that is being hot-unplugged in .cpu_die
hook which runs on the cpu itself. Instead, it should be done in
.cpu_kill which runs on the thread (another cpu) that asks for shutting
down the cpu. Move imx_enable_cpu(cpu, false) call into .cpu_kill
hook, and leave the cpu to be hot-unplugged in WFI within .cpu_die,
so that we can get a more stable cpu hot-plug operation.

ARM: 7608/1: l2x0: Only set .set_debug on PL310 r3p0 and earlier
commit c045e3f13 (ARM: imx: include iram.h rather than mach/iram.h) changed the
location of iram.h, which causes the following build error when building the coda
driver:
drivers/media/platform/coda.c:27:23: error: mach/iram.h: No such file or directory
drivers/media/platform/coda.c: In function 'coda_probe':
drivers/media/platform/coda.c:2000: error: implicit declaration of function 'iram_alloc'

drivers/media/platform/coda.c: In function 'coda_remove':
drivers/media/platform/coda.c:2024: error: implicit declaration of function 'iram_free'
Since the content of iram.h is not imx specific, move it to
include/linux/platform_data/imx-iram.h instead. This is an intermediate solution
until the i.MX iram allocator is converted to the generic SRAM allocator.

This change removes the use of __devinit, __devexit_p, __devinitdata,
