This patch set aims at bringing a basic device tree support for the sam9261.
It's mostly based on the sam9263 and sam9x5 stuff.

Changes since V2:
* removed the smc driver from the serie. It'll be posted in an independent
  serie later.
* removed the DM9000 support (it'll come with the smc driver)
* the sam9261 now supports the Common Clock Framework (CCF). Note: to enable
  the CCF you must remove from the kernel config the platforms that don't
  support it.
* Added basic DT binding for the bus matrix
* Added support for USB host
* Added support for USB gadget
* in dts(i), replaced interrupt-parent with interrupts-extended
* changed the nand partition plan (same as for the sama5d3)
* removed 'mem' parameter in command line
* re-ordered dt-nodes in ascending address order.
* split the lcd support patch in 2 parts (SOC and board)


Change since V1:
* changed the DT representation to use address translation and separate the
  timings' configuration from the device properties by adding a "simple-bus"
  inetrmediate node.
* moved the smc driver from drivers/bus to drivers/memmory
* smc driver now accepts timings in nanoseconds as well as raw register values
* smc driver can clip the timings if they're out of bound and dump them to the
  console
* DM9000 timings are now described in nanosecs (for the virtue of example)

supported features:
* dbgu
* nand
* lcd
* leds
* user buttons
* usb host
* usb gadget

This serie relies on the 3 following patchs:
usb: ohci-at91: fix irq and iomem resource retrieval
usb: at91-udc: fix irq and iomem resource retrieval
ARM: at91: prepare sam9 dt boards transition to common
