This patch fixes a bug where the TS might stop working after suspend/resume.
This patch is under upstream review and it seems it will change a lot.

Without this patch we cannot make the s3c2410/s3c2440 touchscreen
driver work. This will be done in a different way in upstream kernel.
We specify the delay value (S3C2410_ADCDLY).

This adds support for platform_battery driver which allows to specify a set
of power supply properties and callbacks to acquire them. It is needed to
support dumb batteries where all the information about their status can
only be obtained by platform-specific actions such as specific ADC
measurements, some guessimation etc.

This driver can be used for dumb batteries when all knowledge about
their state belongs to the platform that does necessary ADC readings,
conversions, guessimations etc.

In some cases it is desirable to completly disable low-level messages. For
example if you have no uart available for a serial console.
With this patch it is possible to disable low-level messages by setting
CONFIG_S3C_LOWLEVEL_UART_PORT to less then zero.

This is nonportable and wastes a lot of memory and thus should be replaced with
a prober solution asap.

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.

This patch adds a flag to the s3c2410_nand platform data, which configures
whether hardware ecc is used for that chip.
Currently hardware ecc is used if it was compiled into the kernel. But if you
want to build a kernel which runs on multiple devices you might have a
configuration where you have devices which require hw ecc as well as devices
which want software ecc.

The gta02 uses the glamo mfd driver which requires 9 board irqs.

Some boards have a need for a set of extra IRQ numbers, for example some
multifunction devices which do irq demultiplexing require them.
This patch adds S3C2410_BOARD_NR_IRQS which specifies the number of extra board
IRQs. Board specific code would use S3C2410_BOARD_IRQ_START to get the number of
it's first irq.
Since it is possible to support a multiple boards with a single kernel and
there is no easy way to set a CONFIG option to multiple values and only use the
maximum each board which needs board IRQs has do be explicitly added to irqs.h

Early verions off uboot used for the gta02 flashed the nand with ecc information
incompatible to s3c2442 hardware ecc. Disable hardware error correction by
default, unless the bootloader explicitly enables it.

On hardware revision 5 and earlier the leds found on the gta02 are missing a
resistor and reading their gpio pin status will always return 0. So we have to
shadow the led states in software. This is done by "hijacking" the gpio accessor
functions for bank B.

The gta02 has three leds which are connected though gpio pins and thus can get
supported by using the generic leds-gpio driver.
