lis302dl_use_s3c24xx_gpio_spi_bitbang.patch
Change lis302dl driver to use generic spi code. This requires that we define a
s3c24xx_gpio spi bitbang based controller in mach-gta02.c.

Clean out more switch() on version that has no point given the
actual features that (don't) differ on supported GTA02 versions.
We take care about forcing GPS regulator off on neo1973-pm-gps probe,
but we don't take care about killing the UART GPIO so they don't
drive into the powered-down subsystem. We took care of doing that when
we turned off the thing already, but we cannot just call the OFF code
from the probe due to problems with regulator state init.

S3C64XX: DMA support
Add support for the DMA blocks in the S3C64XX series
of CPUS, which are based on the ARM PL080 PrimeCell
system.
Unfortunately, these DMA controllers diverge from the
PL080 design by adding another DMA controller register
and configuration for OneNAND.

If the PCF50633 ADC is disabled, but the charger is enabled we can't determine
the charger type using the pulldown. The safest thing we can do is to fallback
to 100mA that should be supplied according to the USB specs.

We select the PCF50633 core part, which depends on I2C, in our Kconfig. However,
make oldconfig does not automatically resolve this "depends on I2C" dependency.
We should select I2C for GTA02 as it's needed anyway.

If we disable CONFIG_CHARGER_PCF50633 the build fails with a bunch of errors.
This patch defines placeholders for the functions that require the charger. All
users of the function pointers care about the case when they are NULL, so this
won't break anything. Furthermore a small restructuring of the mach file was
necessary to not sprinkle ifdefs all over.

This patch cleans some cruft from neo1973-pm-gsm.c and makes
some changes to the power code for gsm.
First, on probe it enforces GSM is OFF.
Second, when GSM is OFF, it changes the RTS and TXD pins on
UART 0 to be inputs, instead of driving into a dead subsystem
and costing us ~70mA @ 5V constant dissipation (these 3.3V pins
were found at 1.5V due to that).
Third it asserts the GPIO peripheral function when ON, to keep
the same flow for the new interrupt generation workaround code.
Since several people worked on this area before, and maybe the
assertion of GSM OFF is different (it's OFF from bootloader though)
or maybe something else gets broken, I send the patch for comment
before applying it.

This implements a proper scheme of controlling powering on of the Calypso
GSM modem which should be activated with a "push-button" connected to
MODEM_ON line.
Also a workaround for firmware bug of moko10 and earlier implemented to
force calypso to pull IRQ line down after powering on.
The "reset" sysfs node is left for compatibility with userspace (without it
gsm0710muxd breaks) but it does nothing (NC on hardware level on GTA02
anyway).
I tested flashing the GSM firmware (on GTA02) with this patch (using only
fluid and power_on node) and can confirm that it's working as reliably as
with accessing gpio directly per instructions.
The credit goes to Joerg Reisenweber for discussions and clarifications on
how this should be done properly.

Pardon me if I am too verbose but this is my first opportunity to send a patch.
I was wishing to try andy-tracking kernels on GTA01 long ago but It
was FOSDEM and recent threads on the lists asking for GTA01 that made
me do it.
When I participated on the thread
http://n2.nabble.com/empiezo-a-amargarme-con-los-kernels-necesito-consejo-td2347206.html
in the Spanish mailing list asking what kernel to use with which
distribution, I responded that only FSO based supported 2.6.28 and
upwards. I could not resist to brag that I tested 2.6.29 on GTA01 but
only with kexec ( it is possible that my wording was more ambiguous on
the thread).
Nelson Asked if I had problems booting it with u-boot. I tried and was
successful but this time I played a Little with the interface and vala
term and noticed that the on screen keyboard was changing the key
pressed.
Using http://svn.openmoko.org/developers/tick/touchtest/touch_test.py
shown that most of the Up and sometimes the previous Move to where
landing on ([290..310],575).
Revising the code shown that the some of the filters and the option to
disable them were missing on mach-gta01.c.
I have tested the kernel with the patch applied with the filters
disabled and also with them enabled. When the filters are active I
still receive some misplaced up events but much less (the raster
terminal keyboard is usable).
