cc2afa43d4 arm/dt: tegra: add dts file for paz00
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.

a7db2c1593 arm/tegra: Add device-tree support for TrimSlice board
* Add device-tree file for TrimSlice
* Add that to the list of .dts files to build
* Update board-dt.c to recognize TrimSlice board name

v2: Makefile: Add board-trimslice-pinmux.c to obj-$(CONFIG_MACH_TEGRA_DT).
v3: Makefile: Use brackets not braces around var names

4a53f4e692 USB: ehci-tegra: add probing through device tree
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.

4b91b6fb86 arm/tegra: Don't create duplicate gpio and pinmux devices
*_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.

8e267f3da5 arm/dt: tegra devicetree support
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.
