2012-03-15ATMEL: fix nand ecc supportJean-Christophe PLAGNIOL-VILLARD23-26/+23
So we can now choose for the board the ecc mode (ecc soft, soft bch, no ecc and hardware). Set ecc mode in the boards to soft as currently in the driver.

2012-03-01ARM: at91/pio: add new PIO3 featuresNicolas Ferre5-20/+281
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.

The current DT enabled platforms are also modified to use it: - .dtsi files are modified to add Timer Counter Block entries - alias are created to allow identification of each block - clkdev lookup tables are added for clocks identification.

2012-03-01ARM: at91: AIC and GPIO IRQ device tree initializationNicolas Ferre4-61/+168
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>

2012-02-27irq_domain: Centralize definition of irq_dispose_mapping()Grant Likely2-18/+2
