Log:
target/u-boot/patches/uboot-20061030-neo1973.patch: disable HWSWP in LCDCON5 to
make frame buffer organization consistent with what u-boot's CFB driver
supports. Note that this requires pixels in swap screens to be swapped.
This resolves

New Revision: 3776
Modified:
trunk/src/target/u-boot/patches/uboot-usbtty-acm.patch
Log:
This fixes the hang at boot time if usbtty is set but no USB is connected.
http://bugzilla.openmoko.org/cgi-bin/bugzilla/show_bug.cgi?id=887
The problem surfaced in the first place because upstream changed
USBTTY_BUFFER_SIZE from 2048 bytes, which was apparently always big enough, to
256 bytes, which isn't. The logic of the fix is slightly ugly since we could
already exit in usbtty_puts if there is no USB. However, this kills the slight
chance that someone might connect and see the buffered messages.
uboot-usbtty-acm.patch:
- drivers/serial/usbtty.c (__usbtty_puts): allow overwriting of the circular
buffer if usbtty is not configured. This is a slight variation of
http://bugzilla.openmoko.org/cgi-bin/bugzilla/attachment.cgi?id=462

Added:
trunk/src/target/kernel/patches/fbset-gta02-core.patch
trunk/src/target/kernel/patches/fbset-smedia-glamo.patch
Modified:
trunk/src/target/kernel/patches/series
Log:
These are the fbset support patches olv submitted a month ago:
http://lists.openmoko.org/pipermail/openmoko-kernel/2007-December/000322.html
The patches are commented out in "series", since they're still untested
| This patchset adds fbset support to glamofb. This means, it can now
| switch between VGA and QVGA at runtime like GTA01 does.
|
| Stefan has wrote up a howto for GTA01:
|
| http://lists.openmoko.org/pipermail/neo1973-hardware/2007-October/000267.html
|
| It is almost the same for GTA02. The only difference is that the LCM is
| controlled by:
|
| /sys/devices/platform/glamo3362.0/glamo-spi-gpio.0/spi2.0/state
fbset-gta02-core.patch:
- arch/arm/mach-s3c2440/mach-gta02.c (gta02_glamo_pdata): initialize fields for
timing data
fbset-smedia-glamo.patch:
- include/linux/glamofb.h (struct glamofb_platform_data): add fields for timing
data
- drivers/video/glamo/glamo-fb.c: move modeline setting to a function of
itself. Call this function on initialization and set_par.
- drivers/video/glamo/glamo-fb.c (glamofb_cmd_mode): glamo fails to return to
display mode if we switch to and back from cmd mode too quickly. Add a
certain amount of delay after entering cmd mode.
- drivers/video/glamo/glamo-core.c (glamo_engine_reset, glamo_pll_rate,
glamo_engine_reclock), drivers/video/glamo/glamo-core.h
(glamo_engine_reclock), drivers/video/glamo/glamo-fb.c
(glamofb_activate_var): adjust DCLK ratio to match the desired pixclock.
