ARM: at91: dt: at91sam9g45 family and board device tree files Create a new device tree source file for Atmel at91sam9g45 SoC family. The Evaluation Kit at91sam9m10g45ek includes it. This first basic support will be populated as drivers and boards will be converted to device tree. Contains serial, dma and interrupt controllers. The generic board file still takes advantage of platform data for early serial init. As we need a storage media and the NAND flash driver is not converted to DT yet, we keep old initialization for it.

ARM: at91: AIC and GPIO IRQ device tree initialization Both AIC and GPIO controllers are now using the standard of_irq_init() function to initialize IRQs in case of DT use. The DT specific initialization functions are now separated from the non-DT case and are now using "linear" irq domains. The .map() irqdomain operation is responsible for positioning the IRQ handlers. In AIC case, the Linux IRQ number is directly programmed in the hardware to avoid an additional reverse mapping operation. The AIC position its irq domain as the "default" irq domain. For DT case, the priority is not yet filled in the SMR. It will be the subject of another patch. Signed-off-by: Nicolas Ferre <nicolas.ferre@atmel.com>
