Commit 4a53f4e6 "USB: ehci-tegra: add probing through device tree" added
AUXDATA for Tegra's USB/EHCI controller. However, it pointed the platform
data at a location containing the address of the intended platform data,
rather than the platform data itself. This change fixes that.

board-dt-tegra*.c should support any board using Tegra when booted using
device tree. Instead of explicitly listing all the supported boards,
which requires a kernel change for each new board, list the supported SoC
model instead.

Note that the board files do currently have explicit support for setting
up each board's pinmux. However, it's fairly likely that at least the
basic devices on any new board will work just fine as set up by the boot-
loader, and the pinmux data should be moving into device tree soon anyway.

Tegra20 based boards will be handled by the current board-dt.c file. Tegra30
based boards will be handled by a new board-dt-tegra30.c file. Hence rename
the existing board-dt.c to board-dt-tegra20.c to reflect its use.

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
* Undid some accidental 0x -> 0x0 search/replace.

This adds a dts file for paz00. As a side effect, this also enables
the embedded controller which controls the keyboard, touchpad, power,
leds, and some other functions.

Rely on platform_data being passed through auxdata for now; more elaborate
bindings for phy config and tunings to be added.

v2: moved vbus-gpio check to the helper function, added check for !of_node,
    added usb2 clock to board-dt table.

*_pinmux_init() register the GPIO and pinmux devices so that they're ready
before any other device needs them.

*_pinmux_init() are also called by board-dt.c in order to set up the GPIO
and pinmux configurations. In this case, if we register the devices, they
end up being probed once due to this registration, and a second time due
to a device-tree node (or vice-versa). The second probe fails since the
memory regions are already requested. Besides, we don't actually want the
duplicated devices.

To avoid this duplicate registration, modify *_pinmux_init() to check
whether it's running on a DT machine. If not, register the pinmux devices.
If so, don't register them.

Finally, modify board-dt.c to call the *_pinmux_init() after all devices have
been instantiated from device-tree. This allows the GPIO and pinmux devices
to be instantiated and initialized before calling functions to configure the
hardware.

This has one disadvantage: The pinmux and GPIO initialization now happens
after /all/ devices are instantiated, rather than after just gpio and
pinmux but before anything else. So the correct HW configuration is not
in place when e.g. the SD/MMC device is probed. Long-term, this should be
solved by doing both:

a) Initializing the HW state from DT nodes during GPIO and pinmux device
   probe.
b) Using the deferred driver probe mechanism, so that drivers can defer
   their probe until after the gpio and pinmux drivers have probed.

v2: s/int is_dt/bool is_dt/
v3: Use of_machine_is_compatible inside *_pinmux_init() rather than passing
an explicit parameter into the function from outside.

Everything required to populate NVIDIA Tegra devices from the device
tree.  This patch adds a new DT_MACHINE_DESC() which matches against
a tegra20 device tree.  So far it only registers the on-chip devices,
but it will be refined in follow on patches to configure clocks and
pin IO from the device tree also.
