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.

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]

Add WAIT mode (ARM core clock gating) support to imx6q cpuidle driver.
As WAIT mode is broken on imx6q TO 1.0 and 1.1, it only enables the
support for revision 1.2 with chicken bit set.
Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
Move imx6q_cpuidle_driver into a separate file as more codes will
be added when WAIT mode gets implemented as cpuidle.
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
multiplatform on i.MX, which was causing build failures when included
- Device tree updates for at91 dealing mostly with their new

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.
