Resolve longstanding issue noted by Adrian Hunter: confusion
between settting VSEL=0 (which is 1.8V on MMC1) and poweroff.
Also, leave VSEL alone if we're just powering the regulator off.

Device connected to MMC3 is assumed to be self-powered, so
set_power() function is empty. It can't be omited because
host driver requires it.
Array size for hsmmc[] is specified to allocate to allocate
an instance for the third MMC controller.
Also fix a leak which happens if invalid controller id
is passed.

Correct twl4030 MMC power switching: fix voltage ranges reported
for each slot, and handle them fully.
Lies corrected:
- MMC-1 doesn't support the 2.6-2.7 Volt range
- MMC-2 can't normally support anything except 1.8V
Omissions corrected
- MMC-1 *does* handle the 2.8-2.9 Volt range
- MMC-2 can handle 2.5-3.2 Volt cards, given a transceiver
Add transciever support for MMC-2; enable it for Overo and Pandora.
(Depends on something else to have set up pinmuxing for control
signals instead of as MMC2_DAT4..7 pins.)
Also shrink twl4030_hsmmc_info a smidgeon ... padding is all gone.

There is no CONFIG_I2C2_OMAP_BEAGLE in mainline and it is under
removal in linux-omap also so remove this dead code now.

OMAP_TAGS should vanish soon since they're not generic arm tags.
Most of them can be converted to a platform_data or parsed
from a command line like e.g. serial tag.
For OMAP_TAG_USB we just let boards call omap_usb_init()
passing a pointer to omap_usb_config.
Patch updated by Tony for mainline, basically make
n770 and h4 compile. Also folded in a fix for OSK
by David Brownell <dbrownell@users.sourceforge.net>.

This fixes the spurious interrupt issue on a DMA channel.
In OMAP sDMA, contrast to the SDMA.DMA4_CSRi registers, the
SDMA.DMA4_IRQSTATUS_Lj registers are updated regardless of
the corresponding bits in the SDMA.DMA4_IRQENABLE_Lj registers.
Since there are four sDMA interrupt lines and if more than one
line is actively used by two concurrently running sDMA softwares
modules,then the spurious interrupt can be observed on the other
lines.
Fix in this patch will only dispatch the relevant and enabled
interrupts on a particular line thus perevting spurious IRQ.

This patch set up a cmdline option for omap dma for masking the
available channels. It is needed since the OMAP DMA is a system wide
resource and can be used by another software apart from the kernel.
To reserve the omap SDMA channels for kernel dma usage, use cmdline
bootarg "omap_dma_reserve_ch=". The valid range is 1 to 32.

This patch extends command line option "i2c_bus=bus_id,clkrate" so that
it allow to register additional I2C busses that are not registered with
omap_register_i2c_bus from board initialization code.
Purpose of this is to register additional board busses which are routed
to external connectors only without any on board I2C devices.

This patch adds a new command line option "i2c_bus=bus_id,clkrate" into
I2C bus registration helper. Purpose of the option is to override the
default board specific bus speed which is supplied by the
omap_register_i2c_bus.
The default bus speed is typically set to speed of slowest I2C chip on the
bus and overriding allow to use some experimental configurations or updated
chip versions without any kernel modifications.

Also remove board-omap3beagle.h that is not included anywhere,
and move protoype for voiceblue_reset() from board-voiceblue.h
to system.h.
After this patch there are still board-ams-delta.h, board-sx1.h
and board-voiceblue.h that export some functions. These could
be removed if the functions were moved under drivers.
