Without this patch we cannot make the s3c2410/s3c2440 touchscreen
driver work.
Is this delay device-dependant?
Is there a better way to do this?
We specify the delay value (S3C2410_ADCDLY).

This patch allow us to efficiently modify the number of
remaining conversions from the client side. This us useful
when we do not know in advance how many conversions we will
need or when we need to cancel pending conversions.
This change is simple enough to be compatible with existing
code that can just define the new pointer in the callback
and ignore it.
Sample usage:

This patch fixes a typo in the voltage setting of LDO1.
In the function mangle_pmu_pdata_by_system_rev() the value of min_uV
is set twice, while the value of max_uV stays at the initialized
value. This leaves us with .constraints.min_uV = 3300000 and
.constraints.max_uV = 1300000, which is probably not what we want.
This patch is only required on andy-tracking.

Without this jbt6k74 is not seen by the system and consequently
display doesn't work with Qi.
Rebasing to .28 introduced a regression (probably in
a6af63e826b79ae1ba2d8cbfa66805cc2dfe367c) resulting in jbt6k74 no longer
manageable by the kernel. This was unnoticed before because u-boot does its
own LCM initialization. With Qi it resulted in a white screen.
This patch is fixing it by making spi host bus number (unspecified,
defaults to 0) and spi device (jbt6k74) bus number match.

Machines that do not route the USB vbus signal to a GPIO can use this
mechanism as an alternate way for the udc driver to detect the usb
connect/disconnect state, which is useful (for example) to enable the
link up/down state to be determined for the g_ether gadget.

Removes ext4 support from the packaging defconfig; there is little
value in having this built into the kernel, and a bug in the current
2.6.29-rc3 kernel results in the kernel attempting to mount an ext2
rootfs as ext4, which fails.

This reverts commit 962780e3631255fc5423192d0762f30a1fa45239.
Nothing really wrong with it but the resulting kernel was
too big for the GTA01 NAND flash.

this patch adds "force-shutdown" feature for GTA02. When the power button is
held pressed for 8 seconds, the power is turned off. No need to remove the
battery anymore. Patch is against andy-tracking.

This dirty hack adds camera activation/deactivation on open/close.
This code will have to move to a machine/platform area later. The
general driver is the wrong place for it.
It also removes the unconditional activation and moves the domain
setting to the rest of the power control code. (Thanks, Andy !)
Note that opening the camera now always takes about 20 seconds
until the settings are downloaded, not just on the first open.

Filter chains should be completely opaque to the drivers that use it.
We fix this with this patch.
~ Make the "filter chain" a new object.
~ We can build with CONFIG_TOUCHSCREEN_FILTER=n with no problems in
a cleaner way.
~ Update s3c2410_ts.c to use the filter_chain object.
~ Cleanups.

This patch defines a ts_filter_configuration structure to
avoid using void* in the filter initialization, fixing another
upstream correction. This also makes the initialization more readable.
Tested in GTA02/rev6.
Other changes:
~ Comment filter configuration structures.
~ ts_filter.c:ts_filter_chain_create improved.
~ Small cleanups.
~ More TODOs/FIXMEs.
~ Updated GTA02 filter configuration.
~ Updated GTA01 filter configuration.
~ Updated mach-s3c2410/include/mach/ts.h for the new ts. configuration
structure.
~ Updated all the filters to use the new configuration structure.
~ Removed MAX_TS_FILTER_CHAIN constant that is no longer needed.
No more evil casts left it seems.

This patch turns upstream feedback into API modifications and code
improvements. There will be more patches implementing upstream
corrections but this one is the that will make most of the invasive
changes and make the most important improvements to the API.
Tested in a GTA02/rev06.
The goals of this patch are:
* Replace recursive calls with iteration.
* General code improvements.
* Make ts_filter_mean.c a reference for the rest of the filters.
* Make the (almost)minimum number of changes to the other filters so
that they compile and work, patches for cleaning these up will
come next.
* Filters should do what they were doing before.
Some important changes:
* Move "struct ts_filter tsf" in the private structures to force
a crash (or break things) if we forget to remove an open-coded cast.
* ts_filter.c/ts_filter.h
~ API modifications.
* s3c2410_ts.c:
~ Use the new API.
~ Cleanups.
* ts_filter_mean.c
~ Replace with a simple mean.
~ Use as a reference for the new API.
~ Move private structure from the .h to the .c.
* ts_filter_group.c
~ Update to use the new API.
* ts_filter_median.c
~ Update to use the new API.
* ts_filter_linear.c
~ Remove functions that are no longer needed.
Note:
I might leave some TODOs and FIXMEs with this patch. Most of them
will be removed shortly.
