Add the function to register the OHCI platform device, given the root hub
related platform data passed from the board specific code. The platfrom
data provide for overriding the OHCI port power and over-current bits at
the board level.

The patch itself does not change the functionality of
any existing code. PARAM entries in the present GIT kernel
are referred to as slots. New API's being added to the
EDMA driver were referring to these PARAM entries as
"params". This patch updates the terminolgy used in the
EDMA driver.

The reserve_contiguous_params function is used to reserve
a set of contiguous PARAMs. If we do not find a complete
set of contiguous PARAMs, the functions still has to free
every PARAM that it found to be free in the process of finding a
complete set and thus marked as "in use".
This patch mainly deals with correctly handling the
freeing of PARAMs.

The edma_alloc_cont_slots API is used for obtaining a set of
contiguous slots. When we use the "_ANY" option with this
API, by definition of this option it is suppossed to start
looking for a set of contiguous slots starting from slot 64 for
DaVinci SOC's and 32 for DA8xx SOC's. This has been explained in
the API description in the driver itself. So when we use the
"_ANY" option with this API, the slot number passed as
an argument should be a "don't care".
This patch takes care of this condition mentioned above.
When checking to see if the starting slot is a valid number,
it checks to make sure that the "_ANY" option is not used.

On the latest DA850/OMAP-L138 EVM (Beta) the GPIO pin
number of LCD panel power has changed. This patch takes
care of this change. Software will support only Beta
versions of DA850/OMAP-L138 EVM.
In the process, add the missing entry for data pin 0
and remove the GPIO specific pins from da850_lcdcntl_pins
structure. EVM specific muxing for LCD is being done in the
board file now.

Add graphics support for the Sharp LCD035Q3DG01 graphical
LCD that's on the User Interface (UI) daughter card of the
DA830/OMAP-L137 EVM.
The LCD shares EMIFA lines with the NAND and NOR devices that
are also on the UI card so those lines are shared via a couple
of muxes. The muxes are controlled by the 'MUX_MODE' line on
the UI card. The 'MUX_MODE' line is controlled by pin P6 of
a pcf8574 i2c expander that's at i2c address 0x3f on UI card.
The i2c expander is controlled using the gpio infrastructure
from the board code using the 'setup()' and 'teardown()'
routines.

clk_round_rate, clk_set_rate have been updated to handle dynamic
frequency changes.
The motivation behind the changes is to support dynamic CPU frequency
change.
davinci_set_pllrate() changes the PLL rate of a given PLL. This function
has been presented as a generic function though it has been tested only
on OMAP-L138 EVM. No other currently available DaVinci device will probably
use this function, but any future device specific changes will hopefully be
small enough to get taken care using a cpu_is_xxx() macro.

Percpu symbols now occupy the same namespace as other global

Some Blackfin on-chip ROMs utilize some MDMA channels during the suspend

clear all DMA channels when resuming since no DMA could have been running

laziness on the part of the on-chip ROM or boot loader.

This patch adds a resource and corresponding name to the MMCONFIG
structure. This makes allocation simpler (we can allocate the
resource and name at the same time we allocate the pci_mmcfg_region),
