Handle new memory layout.
The "not-needed" memory should not be taken by the framebuffer driver.
Use that for the DRM driver.
Add the cmdq platform device
Set aside 4k for hardware cursor, reject cursors that don't fit.

Change RTS and TXD pins on UART 0 to be inputs only on GTA02.
On GTA01 the UART 0 maybe used otherwise.

This patch fixes the issues of RNDIS on the Openmoko Freerunner (and
subsequently Windows networking with the Freerunner). It arises from the
case where a stall is being issued by the upper level RNDIS driver to
the s3c2410_udc.c in the 2.6.28 series driver and it not being handled
correctly. This patch changes the RNDIS driver to send zero-length
packets instead of a stall, a condition that allowed the udc driver to
function correctly in 2.6.24 series kernels.
Further investigation into the udc driver is recommended. I am currently
looking into it to be able to use the Android ADB gadget driver, which
currently has stability issues using the underlying udc on both Linux
and Windows (although, it's possible that the Android ADB gadget has
problems).
Traces and logs of the USB traffic are available upon request. Thanks to
Aric at SDG Systems for all of his work on this matter.
Regards,
Brian Code

Hello,
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.

If no battery is connected, we periodically get a burst of HDQ error
messages (at least on 3D7K), interrupting whatever we're doing on
the console.
This patch reduces this to only one message per sequence of errors,
and one more message if communication with HDQ is successful later.

This patch explicitly enabled to "camif" clock, to make the driver
work again with Qi commit a24b5fcf84d2cf633a3f660edd23fa4c2a3da231.
Note that this is not fully tested since the Qi change also broke
the LCM driver.

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.

The PLL converts a 26.6 MHz input clock to 87.8 MHz, which is later
divided by two and becomes PCLK. (See comments below for details.)
All this looks like a textbook example for platform stuff, but let's
take it one step a time.

The current version of CPU detection patch from Mark Brown and
Kyungmin Park takes a dump on system_rev. This patch changes it
to retain the low 16 of system_rev from the bootloader ATAG, and
adds access #defines and changes to use them.
No doubt they'll issue a better version of the CPU detection
patch and then this can be reverted.

Use the regulator framework to provide optional support for DVFS in
the S3C64XX cpufreq driver. When a software controllable regulator
is configured the driver will use it to lower the supply voltage when
running at a lower frequency, giving improved power saving.
When regulator support is disabled or no regulator can be obtained
for VDDARM the driver will fall back to scaling only the frequency.
