2a5fdc9add ARM: dt: tegra: invert status=disable vs status=okay
In tegra*.dtsi, set status="disable" for all HW modules that the board
design may choose not to use. Update all boards to specifically enable
any of those modules that are useful by setting status="okay".

This makes board files say which features they do use, rather than which
they don't, which feels more logical. It also makes the .dts files
slightly smaller, at least for existing content.

Put properties in order compatible, reg, interrupts, then anything else

c04abb3a07 ARM: dt: tegra: sort nodes based on bus order
Sort the nodes according to the following rules:
* First, any overrides for properties or nodes created by included files,
  in the order they appeared in the include file.
* Second, any nodes with a reg property, in numerical order.
* Third, any nodes without a reg property, in alphabetical order of node
  name.

The second sorting rule at least will probably help if/when we need to
explicitly insert nodes for the various busses in Tegra; that will just
be an indentation change rather than also a node re-ordering.

5ff488875b ARM: dt: tegra: format regs properties consistently
Place each reg "entry" on its own line, and wrap the whole list in
<> rather than each individual entry.

The convention chosen here is slightly arbitrary, but is not consistent
throughout all Tegra files.

Most of these patches convert code from using static platform data to
 describing the hardware in the device tree. This is only the first
 half of the changes for v3.4 because a lot of patches for this topic
 came in the last week before the merge window.

6f74dc9bc8 gpio: tegra: Dynamically allocate IRQ base, and support DT
Enhance the driver to dynamically allocate the base IRQ number, and
create an IRQ domain for itself. The use of an IRQ domain ensures that
any device tree node interrupts properties are correctly parsed.

Describe interrupt-related properties in the device tree binding docs,
and the contents of "child" node interrupts property.

Update tegra*.dtsi to specify the required interrupt-related properties.

Finally, remove the definition of TEGRA_GPIO_TO_IRQ; this macro no longer
gives correct results since the IRQ numbers for GPIOs are dynamically
allocated.
