Defines a way for drivers to defer execution of resume callbacks
until one or more other driver they are dependent on has itself
resumed.

Creates a new behaviour requested by Will that the red LED on GTA02
is lit during battery charging.and goes out when the battery is full.
This is done by leveraging the PMU interrupts, but in one scenario
there is no interrupt that occurs, when the battery is replaced after
being removed with the USB power in all the while. So a sleepy work
function is started under those circumstances to watch for battery
reinsertion or USB cable pull.
100mA limit was not being observed under some conditions so this was
fixed and tested with a USB cable with D+/D- disconnected. 1A
charger behaviour was also tested.
Showing the charging action exposes some inconsistency in pcf50633
charging action. If your battery is nearly full, it will keep
charging it at decreasing current even after it thinks it is at
100% capacity for a long while. But if you pull that same battery
and re-insert it, the charger state machine in pcf50633 believe it is
full and won't charge it.

Update this old code to clk API, I2C changes, official GPIO API
various struct changes, explicit readl() writel(), DMA API changes.
Still not ready for actual use (eg, I2C) but a LOT closer.

This is the kernel side of an old (2004) samsung camera driver for 2440
It doesn't compile on modern kernel yet, this patch introduces it into the
kernel tree without gross mods, so it is broken code we can start to work on

Currently we are willing to wake from sleep from

Subject: [PATCH] Do not use msleep in the resume path of s3c2410_ts as it
might lockup
For some reason msleep might set the only task running into a suspended
state and no timer will ever wake it up. Use mdelay to avoid this. I was not
able to understand the reasoning of sleeping after enabling the clock. So we
might just remove the msleep/mdelay at all and be fine.

This patch improves the smoothness of suspend and resume action.
Taking out CONFIG_PM_DEBUG allows much more rapid resume (the low level
serial traffic appears to be synchronous)
Added a platform callback in jbt driver and support in pcf50633 so we
can defer bringing up the backlight until the LCM is able to process
video again (which must happen after the glamo is up and producing
video beacuse the LCM is hooked to glamo SPI)
GTA01 should not be affected by all this as the callback will default
to null and it is on pcf50606

Add missing platform_data that caused the GTA01 to crash on suspend/resume

Restore power button functionality after resume operation
Per Werner's suggestion, run the PMU interrupt handler immediately after resume
to clear/handle any pending interrupts from that device. This appears to
resolve the dead-powerbutton-after-resume problem. This is not well-tested;
need feedback to see if there are any side-effects or other problems.

Patch to register the SPI device and thus the save/resume for the display
This patch does *NOT* resolve this problem, but it does make things a bit
better. The SPI device name changed with 2.6.24, and the change was made for
the gta02 but never propagated to the gta01. With this change, you'll now see
the entries for the spi bus and the display controller in /sys; and the display
controller suspend/resume functions will be called.

Headphone jack detection is bouncy, it can trigger multiple interrupts
on insertion or removal. This patch adds a workqueue that waits out the
interrupt spew in 100ms units, and if it sees no more interrupts for 100ms
only then samples and reports the jack state. I was unable to get a bounce
after 20 or so tries after this.
