[ Stop kernel from hanging every once in a while during Glamo
initialization. ]
debug-glamo-fb-cmdqueue-wait-timeout.patch

This patch seems to alleviate the symptoms but doesn't cure them.
Keep it to keep development going, until we have a proper solution.

This is a temporary work-around Mike Westerhof for this bug:
http://bugzilla.openmoko.org/cgi-bin/bugzilla/show_bug.cgi?id=788
See also
http://lists.openmoko.org/pipermail/openmoko-kernel/2008-February/000804.html
(It's the 2nd option.)
We may settle on a different solution in the future, depending on
feedback from upstream.

S3C24xx ECC mis-calculates the bit to flip:

If the error couldn't be corrected, we returned "no problem" :-(

On GTA02 we use FIQ to manage the vibrator IO now. That
is necessary because we stole timer3 from doing hw pwm
for vibrator. This keeps the same UI in /sys but does
"bitbang pwm" on the same vibrator GPIO

This makes the FIQ stuff specific to one of the timers on the
s3c244x and adds the platform stuff for fiq in the gta02 init
Currently one sysfs node is exposed, a count of FIQ events

Adds a C-based FIQ ISR which is very convenient (and unusual --
normally you have to do FIQ ISR in assembler only).
Based on my article:
http://warmcat.com/_wp/2007/09/17/at91rm9200-fiq-faq-and-simple-example-code-patch/
Implemented as a platform device and driver.
Suspend / resume is tested and works.

Fail the build noisily if "mkimage" can't be found, e.g., if we forgot to add
the u-boot directory to PATH.

Disable the hardware ECC checking on S3C2440 based platforms (HXD8, SMDK2440,
GTA02) for the time being, since our u-boot doesn't yet support it for 2k page
size NAND

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.

Modify GTA02 power manager for bluetooth.
1. Default power value isn't correct. Now we set pcf50633 LDO4 to 3.2 voltage.
2. Separate GTA01 and GTA02 source code.
3. Add pcf50633 API for enable register.

Moved shared PMU code from pcf50606.h and pcf50633.h (which prevented inclusion
of both at the same time) to pcf506xx.h
- include/linux/pcf50606.h (struct pmu_voltage_rail, enum pmu_event, pmu_cb):
moved to pcf506xx.h
- include/linux/pcf50633.h (struct pmu_voltage_rail, enum pmu_event, pmu_cb):
moved to pcf506xx.h

Add the Samsung S3C2442B CPU idcode to the samsung s3c24xx platform code
and fix a Kconfig typo related tot the 2442.
|

This is a patch that seems to make the USB hangs on the S3C2440 go away. At
least a good amount of ping torture didn't make them come back so far.
The issue is that, if there are several back-to-back packets,
sometimes no interrupt is generated for one of them. This
seems to be caused by the mysterious dual packet mode, which
the USB hardware enters automatically if the endpoint size is
half that of the FIFO. (On the 2440, this is the normal
situation for bulk data endpoints.)
There is also a timing factor in this. I think what happens is
that the USB hardware automatically sends an acknowledgement
if there is only one packet in the FIFO (the FIFO has space
for two). If another packet arrives before the host has
retrieved and acknowledged the previous one, no interrupt is
generated for that second one.
However, there may be an indication. There is one undocumented
bit (none of the 244x manuals document it), OUT_CRS1_REG[1],
that seems to be set suspiciously often when this condition
occurs. There is also CLR_DATA_TOGGLE, OUT_CRS1_REG[7], which
may have a function related to this. (The Samsung manual is
rather terse on that, as usual.)
This needs to be examined further. For now, the patch seems to do the
trick.
Note that this is not a clean solution by any means, because we
might potentially get stuck in that interrupt for quite a while.

MTD: S3C24XX large page NAND support
This adds support for using large page NAND devices
with the S3C24XX NAND controller. This also adds the
file Documentation/arm/Samsung-S3C24XX/NAND.txt to
describe the differences.

This is a MMC/SD driver for the Samsung S3C24xx SD/MMC controller, originally
developed years ago by Thomas Kleffel <tk@maintech.de>.
Due to time restraints, he had no time to further maintain the driver and
follow the mainline Linux changes in the SD/MMC stack.
With his authorization, I have taken over the task of making it compliant to
the current mainline SD/MMC API and take care of the mainline kernel merge.
After a potential kernel inclusion, we would co-maintain the driver.

Use FIC's own USB Vendor ID rather than NetChip's
Yes, we could solve this by some modprobe.conf parameters, but I'd like to
rather not rely on this.
