Linus Walleij 6568eccd10 ARM: nomadik: get rid of explicit ethernet GPIO management
We used to set up the GPIO used for the SMC ethernet IRQ by
requesting the GPIO line explicitly. As we recently established
that specifying the GPIO controller as interrupt parent and
requesting one of its interrupts by reference should be enough,
we do away with this. Incidentally, the Nomadik GPIO chip driver
handles this just fine: the IRQ is set up and fired as expected.

Linus Walleij c641d4dfef ARM: nomadik: add the new clocks to the device tree
This revamps the device tree to fit with the new clock
implementation and brings it quite a bit closer to how
the hardware actually works.

After this the clock implementation knows about all
clock gates and will gate off all unused clocks at
boot time and save a bit of power.

Linus Walleij 49932f5ef1 ARM: nomadik: move the pin configuration to DT
This moves the pin configuration for the Nomadik over to the
device tree using Gabriel's bindings. Remove the auxdata
nailing down the name of the pin controller as this is no
longer necessary.

This adds device tree hunks for the LED and userbutton on the
USB S8815 board, and set up a heartbeat trigger on the LED and
an escape key on the user button. Alter the defconfig to enable
these standard DT-enabled GPIO drivers.

Linus Walleij b98da4db29 ARM: nomadik: fix IRQ assignment for SMC ethernet
The assignment of IRQ for the SMC91x ethernet adapter had two
problems making it non-working:

- It was not put into the ethernet device node. Let's do this
  by using the board-specific overlay, so we can make other
  overlays on other Nomadik boards.

- The IRQ number was actually completely wrong, this was the
  number for NHK8815, not S8815.

After this ethernet starts working on the USB S8815.

Support basic device tree boot on the Nomadik. Implement the
support in the cpu file with the intent of deleting the board
files later. At this stage IRQ controllers, system timer,
l2x0 cache, UARTs and thus console boot is fully functional.
Patch out the code adding devices by initcalls for now so
as not to disturb the boot.
