pxa_pm_prepare() tried to validate the suspend method type.  As
noted in previous commits:
	eb9289eb
	9c372d06
	e8c9c502

the checking of the suspend type in the 'prepare' method is the
wrong place to do this; use the 'valid' method instead.  This
means that pxa_pm_prepare() can be entirely removed.

Move the pm_ops structure into the PXA25x and PXA27x support
files.  Remove the old pxa_pm_prepare() function, and rename
the both pxa_cpu_pm_prepare() functions as pxa_pm_prepare().
We'll fix that later.

The PXA CKEN changes broken syspend/resume on the pxa27x. This patch
corrects the problem and fixes another couple of bad references.

This patch removes the unnecessary bit number from CKENnn_XXXX
definitions for PXA, so that

	CKEN0_PWM0 --> CKEN_PWM0
	CKEN1_PWM1 --> CKEN_PWM1
	...
	CKEN24_CAMERA --> CKEN_CAMERA

The reasons for the change of these defitions are:

1. they do not scale - they are currently valid for pxa2xx, but
definitely not valid for pxa3xx, e.g., pxa3xx has bit 3 for camera
instead of bit 24

2. they are unnecessary - the peripheral name within the definition
has already announced its usage, we don't need those bit numbers
to know which peripheral we are going to enable/disable clock for

3. they are inconvenient - think about this: a driver programmer
for pxa has to remember which bit in the CKEN register to turn
on/off

Another change in the patch is to make the definitions equal to its
clock bit index, so that

   #define CKEN_CAMERA  (24)

instead of

   #define CKEN_CAMERA  (1 << 24)

this change, however, will add a run-time bit shift operation in
pxa_set_cken(), but the benefit of this change is that it scales
when bit index exceeds 32, e.g., pxa3xx has two registers CKENA
and CKENB, totally 64 bit for this, suppose CAMERA clock enabling
bit is CKENB:10, one can simply define CKEN_CAMERA to be (32 + 10)
and so that pxa_set_cken() need minimum change to adapt to that.

Patch from Richard Purdie

The turbo flag is in bit 0 of the CLKCFG register, not bit 1.
This patch corrects this so get_clk_frequency_khz returns a correct
value.

To allow multiple platforms to use the PXA27x OHCI driver, the platform
code needs to be moved into the board specific files in
arch/arm/mach-pxa. This patch does this for mainstone and adds
preliminary hooks to allow other boards to use the driver.

This has been compile tested for mainstone and successfully run on Spitz
(Sharp Zaurus SL-C3000) with the addition of an appropriate board
support file.

Patch from Todd Poynor

Add symbols for PXA2xx PWRMODE register M field that selects low-power
mode, replace unadorned constants.  Honor power mode parameter of
pxa_cpu_suspend(mode), no longer force to 3 (sleep).  Full Deep Sleep
low-power mode support for PXA27x is pending generic PM interfaces to
select more than 2 suspend-to-RAM-style power modes, but this is
expected soon. This can be hardcoded in the meantime by replacing the
pxa_cpu_suspend() parameter value.  From David Burrage and Todd Poynor.
Try #2 removes one of the register copies and moves the code to save the
pxa_cpu_suspend parameter to immediately surround the call that requires
the parameter value be preserved.

Patch from Todd Poynor

Add support for PXA27x Standby mode, a low-power mode that retains CPU
and some peripheral state (the existing "sleep" mode is a power-power
mode that retains less state). Activated via:
echo -n standby > /sys/power/state

Patch from Todd Poynor

PXA27x sleep fixes:
* set additional sleep/wakeup registers for Mainstone boards.
* move CKEN=0 to pxa25x-specific code; that value is harmful on pxa27x.
* save/restore additional registers, including some found necessary for
C5 processors and/or newer blob versions.
* enable future support of additional sleep modes for PXA27x (eg,
standby, deep sleep).
* split off cpu-specific sleep processing between pxa27x and pxa25x into
separate files (partly in preparation for additional sleep modes).
Includes fixes from David Burrage.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
