To give one place to setup the pins that are used as GPIOs instead
of as their pinmuxed functions. Specifying enabled as false explicitly
disables the gpio mode of that pin (if left on by firmware).

This should remove the need for calling these from specific drivers and
thus reduce tegra-specific code from them.

The APB DMA block handles DMA transfers to and from some peripherals
in the Tegra SOC.  It reads from sequential addresses on the memory
bus, and writes repeatedly to the same address on the APB bus.

Two transfer modes are supported, oneshot for transferring a known
size to or from a peripheral, and continuous for streaming data.
In continuous mode, a callback occurs when the buffer is half full
to allow the existing data to be handled and a new request queued.x

Colin Cross c5f04b8d10 [ARM] tegra: pinmux: add safe values, move tegra2, add suspend
- the reset values for some pin groups in the tegra pin mux can result in
functional errors due to conflicting with actively-configured pin groups
muxing from the same controller. this change adds a known safe, non-
conflicting mux for every pin group, which can be used on platforms
where the pin group is not routed to any peripheral

- also add each pin group's I/O voltage rail, to enable platform code to
map from the pin groups used by each interface to the regulators used
for dynamic voltage control

- add routines to individually configure the tristate, pin mux and pull-
ups for a pingroup_config array, so that it is possible to program
individual values at run-time without modifying other values.
this allows driver power-management code to reprogram individual
interfaces into lower power states during idle / suspend, or to
reprogram the pin mux to support multiple physical busses per
internal controller (e.g., sharing a single I2C or SPI controller
across multiple pin groups)

- move chip-specific data like pingroups and drive-pingroups
out of the common code and into chip-specific code

- fix debug output for group with no pullups

- add a TEGRA_MUX_SAFE function.  Setting a pingroup to TEGRA_MUX_SAFE
will automatically select a mux setting that is guaranteed not to
conflict with any of the hardware blocks.

but remains powered during the cpu suspend and idle modes that power
down the CPU and the GIC.

Jeremy Kerr 0ea1293009 arm: return both physical and virtual addresses from addruart
Rather than checking the MMU status in every instance of addruart, do it
once in kernel/debug.S, and change the existing addruart macros to
return both physical and virtual addresses. The main debug code can then
select the appropriate address to use.

This will also allow us to retreive the address of a uart for the MMU
state that we're not current in.

Updated with fixes for OMAP from Jason Wang <jason77.wang@gmail.com>
and Tony Lindgren <tony@atomide.com>, and fix for versatile express from
Lorenzo Pieralisi <lorenzo.pieralisi@arm.com>.
