[PATCH] spi: ads7846 driver

This is a driver for the ADS7846 touchscreen sensor, derived from
the corgi_ts and omap_ts drivers. Key differences from those two:

- Uses the new SPI framework (minimalist version)
- <linux/spi/ads7846.h> abstracts board-specific touchscreen info
- Sysfs attributes for the temperature and voltage sensors
- Uses fewer ARM-specific IRQ primitives

The temperature and voltage sensors show up in sysfs like this:

$ pwd
/sys/devices/platform/omap-uwire/spi2.0
$ ls
bus@ input:event0@ power/ temp1 vbatt
driver@ modalias temp0 vaux
$ cat modalias
ads7846
$ cat temp0
991
$ cat temp1
1177
$

So far only basic testing has been done. There's a fair amount of hardware
that uses this sensor, and which also runs Linux, which should eventually
be able to use this driver.

One portability note may be of special interest. It turns out that not all
SPI controllers are happy issuing requests that do things like "write 8 bit
command, read 12 bit response". Most of them seem happy to handle various
word sizes, so the issue isn't "12 bit response" but rather "different rx
and tx write sizes", despite that being a common MicroWire convention. So
this version of the driver no longer reads 12 bit native-endian words; it
reads 16-bit big-endian responses, then byteswaps them and shifts the
results to discard the noise.

[PATCH] SharpSL: Abstract c7x0 specifics from Corgi Touchscreen driver

Separate out the Sharp Zaurus c7x0 series specific code from the Corgi
Touchscreen driver. Use the new functions in corgi_lcd.

[PATCH] SharpSL: Abstract c7x0 specifics from Corgi Touchscreen driver

Separate out the Sharp Zaurus c7x0 series specific code from the Corgi
Touchscreen driver. Use the new functions in corgi_lcd.c via sharpsl.h for
hsync handling and pass the IRQ as a platform device resource. Move a
function prototype into the w100fb header file where it belongs.

This enables the driver to be used by the Zaurus cxx00 series.

Linux-2.6.12-rc2

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
