AUX level detection is inverted based on GTA01 or 02

Reported-by: John Lee <john_lee@openmoko.com>
We don't reset the devices either at init or resume, where init
means use the BOOT bit to reload device calibration coefficients
from internal EEPROM. John Lee saw brain-damaged behaviour after
resume and sometimes after boot (since it may not have lost power
to force a BOOT itself that makes sense).
This patch
- adds a diagnostic dump feature down /sys
- forces BOOT action on init and resume, and waits for
completion
- makes sure XYZ capture is enabled on resume
- adds some constants in the .h and removes some magic numbers
in the code by using them

Touchscreen on GTA01-02 experiences noise on the channel that serves the
"tall axis" of the LCM. The sample quality of the other axis is good.
The bad samples have a characteristic of one shot excursions that can
reach +/- 20% or more of the sample average.
Previously, we had a simple averaging scheme going in the touchscreen
driver that summed up 32 x and ys and then divided it by 32. This patch
first tidies up the existing code for style, then adds a new "running
average" concept with a FIFO. The running average is separate from the
summing average mentioned above, and is accurate for the last n samples
sample-by-sample, where n is set by 1 << excursion_filter_len_bits in the
machine / platform stuff.
The heuristic the patch implements for the filtering is to accept all
samples, but tag the *previous* sample with a flag if it differed from
the running average by more than reject_threshold_vs_avg in either
axis. The next sample time, a beauty contest is held if the flag was
set to decide if we think the previous sample was a one-shot excursion
(detected by the new sample being closer to the average than to the
flagged previous sample), or if we believe we are moving (detected by
the new sample being closer to the flagged previous sample than the
average. In the case that we believe the previous sample was an
excursion, we simply overwrite it with the new data and adjust the
summing average to use the new data instead of the excursion data.
I only tested this by eyeballing the output of ts_print_raw, but it
seemed to be quite a bit better. Gross movement appeared to be
tracked fine too. If folks want to try different heuristics on top
of this patch, be my guest; either way feedback on what it looks like
with a graphical app would be good.

From dc6d335b467646d802a21ea6b925ee97e83e07be Mon Sep 17 00:00:00 2001

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.

struct input_dev in include/linux/input.h used to have a union
cdev which contained the associated device struct pointer. This
got simplified out in 2.6.25, so this patch removes cdev from
our drivers that used it before.

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.

This patch disables the reporting of touchscreen-like devices via
/dev/input/mice. In the Neo1973 (much like other handheld devices),
we need this to distinguish between the touchscreen (which uses tslib)
and optional additional usb/bluetooth mice that might be attached.

As it is, all instances of ->release() for files that have ->fasync()
need to remember to evict file from fasync lists; forgetting that
creates a hole and we actually have a bunch that *does* forget.
So let's keep our lives simple - let __fput() check FASYNC in
file->f_flags and call ->fasync() there if it's been set. And lose that
crap in ->release() instances - leaving it there is still valid, but we
don't have to bother anymore.

The SGI Volume Button interface driver uses GPL-only symbols
platform_driver_unregister and platform_driver_register, but
lacks license specification. Thus, when compiled as a module,
this driver cannot be installed. This patch fixes this by
adding the MODULE_LICENSE() specification.

Separate building of corgi_ssp.c, and introduce a new hidden config option
CONFIG_CORGI_SSP_DEPRECATED for this. Aslo mark corgi_ts.c and corgi_bl.c
as deprecated.
This unbreaks the legacy configs in {corgi,spitz}_defconfig, however, SPI
based ADS7846 touchscreen driver and a new SPI-based corgi_lcd.c driver
with integrated backlight support are recommended.

This updates most of the OMAP drivers which are in mainline to switch to
using the cross-platform GPIO calls instead of the older OMAP-specific
ones.
This is all fairly brainless/obvious stuff. Probably the most interesting
bit is to observe that the omap-keypad code seems to now have a portable
core that could work with non-OMAP matrix keypads. (That would improve
with hardware IRQ debouncing enabled, of course...)
