Signed-off-by: Andy Green <andy@openmoko.com>

Attached is a patch that has greatly reduced the frequency of failures
to resume (due to an oops from the glamo resume handler), and the
dreaded "white screen after resume". I can't say that it fixes all of
these, although I have yet to see the white-screen since applying this
patch and suspending/resuming several hundred times (with the 30-second
suspend on the 2008.8 image and the endless stream of GSM error messages
generated by something in that image, it has proved to be very useful to
do an automated stress test!)
This patch will apply to stable, and should make stable slightly more,
well, "stable".
[Feel free to remove the debug messages if someone feels strongly about
that; I left them in because I think they might be useful in triaging
further crashes; I'm not at all convinced that this patch will fix all
the cases of resume failures.]
[[And, yes, this is ugly, really ugly.]]
[[[Oh yeah - there's still one extreme case that will result in an oops:
if a dependent driver is built as a module, and it is unloaded, and it
happened that the preceding suspend/resume was aborted, and that abort
happened between the dependent driver and the driver upon which it is
dependent, then a list entry will be left behind referencing the
unloaded module. There's just no good way to fix that given the way the
resume dependency plumbing is connected up right now, so just avoid
using modules for any of the drivers involved in the resume dependency
stuff.]]]

commit 905d2fc9c45f622418ce9ef4e67c23453aab7571

always-call-resume-dependencies.patch
Ensure that a dependent resume handler is always executed,
even if the resume handler for driver upon which it is
dependent never suspends (and therefore never resumes either).
Also make sure that we do not end up with duplicate
dependencies registered, something that can happen if the
suspend is aborted due to driver failure or an early resume
(such as occurs when the GSM interrupts during suspend).

This problem was caused by insufficient timeout waiting for pcf50633 to resume
and broken code to detect timeout exhaustion.
Although I'd like to think it has something to do with mmc resume woes it should make a panic
and subsequent emergency spew on UART2 if that had been the case.
Took the opportunity to move the stuff to show completion of probe to later in the
pcf50633 probe and tighten readiness test.

This patch is the pcf50606 equivalent of the pcf50633 patch that
disables interrupts from the chip until after resume is complete.
In order to ensure no data is lost, the work function is called
post-resume to process any pending interrupts.
Most of the code was quite literally re-used from Andy Green's
original patch.

To see if some subtle race is involved, Sean has tried
removing syslog traffic during resume and found he was
not seeing the resume crash any more. We're giving it
a try to see if it changes the behaviour for anyone
else. It would mean we have a pretty fine race in there
somewhere.

We at least always enabled backlight on resume, this patch
changes us to set backlight back to last requested backlight
brightness level on resume. Note it means that you can
resume with screen blanked, but it should come back if that
happened with touchscreen action as usual.
/sys/class/backlight/pcf50633-bl/actual_brightness
and
/sys/class/backlight/pcf50633-bl/brightness
seem to agree after resume when reportedly they didn't before.

This patch adds a sysfs node:
/sys/class/i2c-adapter/i2c-0/0-0073/force_usb_limit_dangerous
it allows to force the charging limit regardless of the one chosen
by pcf50633 kernel driver. As such, if you write a charging limit
here that is not suitable for the power source, and the power source
is not current limited on its side, it could draw more current than
your power source can handle, burn down you house, etc.
If you're certain that your power supply can handle it, you can use
this on your own responsibility to make the amount drawn by the
PMU match what you believed your power supply could handle.
Example usage, in case where you have a dumb 500mA USB charger that
does not have the ID resistor:
# cat /sys/class/i2c-adapter/i2c-0/0-0073/charger_type
host/500mA usb mode 100mA <=== dumb charger does not ennumerate us
# echo 500 > /sys/class/i2c-adapter/i2c-0/0-0073/force_usb_limit_dangerous
# cat /sys/class/i2c-adapter/i2c-0/0-0073/charger_type

We leave SECOND unmasked on resume, it's like the
situation at probe() time, but there it makes us
turn SECOND off after coldplug action. So we need
to act like after that has happened, not exactly
