The ports are used as follows:
UART1/A: Routed to debug dongle
UART2/B: GPS
UART3/C: Bluetooth
UART4/D: Routed to debug dongle
UART5/E: Not connected
The debug dongle has jumpers to connect either UART1/A or UART4/D to
the DB-9 connector. UART1/A is typically used on Cardhu, and is the option
we assume here.
For now, only enable UART1/A, and explicitly disable all other ports.
The explicit disable prevents the message "of_serial 70006040.serial:
no clock-frequency property set" being printed during boot.
Enabling the other ports requires their clocks to be enabled, or accesses
to the registers will hang. At present, this requires adding entries into
board-dt-tegra30.c's tegra_dt_clk_init_table[]. Lets punt on that and wait
for the common clock bindings to set this all up, although that will also
requiring adding clock support to 8250.c.
While we're at it, fix board-dt-tegra30.c to enable the correct clock for
the debug UART. We got away with this before, because the bootloader already
enabled it.

Initially, copied guruplug-setup.c and did s/guruplug/dreamplug/g.

After talking to Arnd Bergman, chose an incremental approach to adding
devicetree support. First, we use the dtb to tell us we are on the
dreamplug, then we gradually port over drivers.
Driver porting will start with the uart (see next patch), and progress
from there. Possibly, spi/flash/partitions will be next.
When done, board-dt.c will no longer be dreamplug specific, and dt's can

An additional .dtsi file is created to describe the generic
SAM9x5 CPU Module (CM).
Device tree source files for each Evaluation Kit that are using
the generic CPU Module and the carrier board. The selection of
available peripherals is done in this .dts file.

Add a helper function for finding the index of a string in a string
list property. This helper is useful for bindings that use a separate
*-name property for attaching names to tuples in another property such
as 'reg' or 'gpios'.

A significant part of the changes for these two platforms went into
power management, so they are split out into a separate branch.

Convert tegra20 IRQ intialization to the GIC devicetree binding. Modify the
interrupt definitions in the dts files according to
Documentation/devicetree/bindings/arm/gic.txt
v3 (swarren):
* Moved of_irq_init() call into board-dt.c to avoid ifdef'ing it.
- Even with a dummy replacement if !CONFIG_OF, the reference from
tegra_dt_irq_match[] to gic_of_init() would still have to be ifdef'd
- It's plausible that tegra_dt_irq_match[] may need to contain more
entries in the future, and defining what they are seems more suitable
for board-dt.c than irq.c
v2 (swarren):
* Removed some stale GIC init code from board-dt.c

Mark any SDHCI controllers that aren't registered by the board files as
disabled in the device-tree files.
In practice, these controllers:
* Have nothing hooked up to them at all, or
* For ports intended for SDIO usage, the drivers for anything that might
be attached are not in the device-tree yet. If/when drivers appear, the
SD/MMC port can be re-enabled.
The only possible exception is TrimSlice's mico SD slot, but that wasn't
enabled in the board files before anyway, and doesn't work when all the
SDHCI controllers are enabled anyway.

Mark any serial ports that aren't registered by the board files as disabled
in the device-tree files.
In practice, none of the now-disabled ports ended up succeeding device
probing because of the missing clock-frequency property. However,
explicitly marking the devices disabled has the advantage of squashing
the dev_warn() the failed probe causes, and documenting that we intend
the port not to be used, rather than accidentally left out the property.

The command-lines present in the existing /chosen node are not necessarily
correct for all users. Ideally, we should simply use the command-line
supplied by the boot-loader.
In fact, using the boot-loader's cmdline is quite easy; either the
bootloader fully supports DT, in which case it can modify the DT passed
to the kernel to include its command-line, or CONFIG_APPENDED_DTB can
be used in conjunction with CONFIG_ARM_ATAG_DTB_COMPAT, and the kernel
will substitute the bootloader's command-line into the DT.
