This patch is to register pwm as platform driver to keep the PWM-related
config when system is in suspend/resume. This could fix the following
issue after resume:
- HDQ read timeout
- LEDs blinked abnormally(if LEDs is driven by PWM)

Add missing platform_data that caused the GTA01 to crash on suspend/resume
The interface to the jbt6k74 driver changed slightly; this patch adds the
missing platform_data for the GTA01. This prevents a crash while suspending.
This patch also makes some minor changes to cleanup and clarify some debug
messages.

Updated patch to preserve the power state of the GPS on the GTA01
Currently the GPS is powered up after a suspend/resume occurs. This patch will
only power the GPS back up if it was powered up when the GTA01 suspended.

Patch to register the SPI device and thus the save/resume for the display
This patch does *NOT* resolve this problem, but it does make things a bit
better. The SPI device name changed with 2.6.24, and the change was made for
the gta02 but never propagated to the gta01. With this change, you'll now see
the entries for the spi bus and the display controller in /sys; and the display
controller suspend/resume functions will be called.

- Any setting of any PIN on bank B will undo the LED setting.
Introduce neo1973_gpb_set_pin to set the PIN in a way not losing
the LED or any other shadowed setting.
- Update users of GPBXY for gta01 and gta02.

Only enable or disable the interrupt if we see we are in the opposing state.
Also force that damn GSM download signal deasserted on probe at the time we
set the logical state for it to deasserted.

Similar to the neo1974_pm_gsm.c keep a static struct around. On suspend
we will save the current power state, on resume we will use this
information to enable power of the GPS only when it was powered on before.
This is passing basic tests with screen /dev/ttySAC1 on suspend and resume.
Only do this for the GTA02 as I don't have a gllin setup for the GTA01
I wonder why the suspend and resume code is not using gps_pwron_set and why
for the GTA02 we need to keep the state of the GPIOs, this should be done
by the s3c code.

GTA02_GPIO_nDL_GSM defaults to high/1. On resume do not enable the DL_GSM if
it was not enabled before. This is stopping the storm of interrupts.
Fix the logic in the download file handling. Downloads are disabled (0) when
the GTA02_GPIO_nDL_GSM is high (1). To enable downloading set
GTA02_GPIO_nDL_GSM to low (0, !on). Disable the jack interrupt while download
the is active. When disabling download we will get a couple of jack interrupts
but this is hardly avoidable.
Avoid reading the GPIO value if we do not even have a console set.

Add function
int gta02_get_pcb_revision(void)
which returns state of GTA02 PCB revision pins. It is also called
and logged during boot with KERN_INFO. The results look like:
b9 b8 b2 b1 b0
GPD4 GPD3 GPD0 GPC15 GPC13
GTA02 A5 and before: 0x000
GTA02 A6 : 0x001

Unless I really really missed the point, there is no support for enabling
USB Host power for USB host mode. This patch adds a /sys node for GTA02
that allows control of the charge pump for 5V out on the USB mini connector
It doesn't change any logical mode in the CPU, just enables (1) and disables
(0) USB host power.

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

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.

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.

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.

The initialization of clocks uses mutexes, but we execute the resume in
an interrupt context. We therefore have to hand this task to a non-interrupt.

Since 2.6.23 kbuild produces a 3GB arch/arm/boot/Image because it includes a
.note.gnu.build-id section at address 0 which is followed by 3GB of 0x00.
The --build-id option is set in the toplevel Makefile.
This patch explicitly puts the notes section after the TEXT section.
