Jean-Christophe PLAGNIOL-VILLARD eb5e76ffd4 ARM: at91: add pmc DT support
Specified the main Oscillator via clock binding.
This will allow to do not hardcode it anymore in the DT board at 12MHz.

Nicolas Ferre 582d5fbd4e ARM: at91/pio: add new PIO3 features
This patch adds the support for new PIO controller found on some
at91sam SOCs.
- more peripheral multiplexing
- more features to configure on a PIO (pull-down, Schmitt trigger, debouncer)
- support for several IRQ triggering features (type and polarity)

Support for those new features are retrieved from the device tree
compatibility string.

Debugfs at91_gpio file is updated to monitor configuration.

Nicolas Ferre 21f8187278 ARM: at91/gpio: add irqdomain and DT support
Add "legacy" type of irqdomain to preserve old-style numbering
and allow smooth transition for both DT and non-DT cases.

Original idea and code by Jean-Christophe Plagniol-Villard.

Nicolas Ferre 467f1cf504 ARM: at91/at91sam9x5: Device tree definition files
Device tree include file for the AT91SAM9x5 SoC family.
An additional .dtsi file is created to describe the generic
SAM9x5 CPU Module (CM).
Device tree source files for each Evaluation Kit that are using
the generic CPU Module and the carrier board. The selection of
available peripherals is done in this .dts file.
