PXA processors have several low-power modes. Currently kernel supports

The default value is 16 IRQs. Zylonite needs 32, ASIC3 based boards need 70.

My problem is still that due to the way IRQ_GPIO is hardcoded, ASIC3 based boards
need 70 IRQs starting at IRQ_BOARD_START. If I define ASIC3 IRQs similar to LoCoMo
or SA1111, things break as soon as something selects PXA_HAVE_BOARD_IRQS.
Increasing the default number of board IRQs to 70 instead doesn't seem very nice.

Firstly, this patch makes the palm27x asoc driver a little more sane. Also,
since all affected devices use GPIO95 as AC97_nRESET, this patch sets that
properly. Affected are PalmT5, TX and LifeDrive.

Currently there are two possible platform datas for the PXA AC97 driver:
one supported by the generic AC97 driver only which provides callbacks
to allow board-specific configuration at stream startup and teardown,
and another for pxa2xx-ac97-lib which allows configuration of the reset
GPIO for PXA2xx CPUs.

Obviously this won't actually work when using the generic AC97 driver
since the drivers will attempt to parse the platform data in both
formats. Fix this by merging the two structures.

To compile, this patch depends on the "regulator: Allow init data to be

add the init_data field to struct bq24022_mach_info.
It also depends on the "add optional OTG transceiver and voltage

OMAP wishes to pass state to the boot loader upon reboot in order to
instruct it whether to wait for USB-based reflashing or not.  There is
already a facility to do this via the reboot() syscall, except we ignore
the string passed to machine_restart().

This patch fixes things to pass this string to arch_reset().  This means
that we keep the reboot mode limited to telling the kernel _how_ to
perform the reboot which should be independent of what we request the
boot loader to do.

The remaining registers are separated into:

   - <mach/regs-rtc.h>
   - <mach/regs-intc.h>

and then we can remove pxa-regs.h completely. Instead of #include this

1. include the specific <mach/regs-*.h> with care (if that's absolutely

Move the processor specific initialization (largely resources initialization)
out of soc_common_drv_pcmcia_probe() into dedicated sa11xx_drv_pcmcia_probe()

By doing this, we are now able to move the PCMCIA related definitions out of
pxa-regs.h and back into pxa2xx_base.c.

As a result, remove that reference of _PCMCIA1IO in arch/arm/mach-pxa/viper.c.
