The NAND Flash controller for SAMA5D2 has small differences that make it impossible to use the existing driver for SAMA5D3. This patchset uses the device tree's compatible string to get those differences, and the code is slightly modified to handle them. Applies on the Atmel Linux 4.1 branch for now, but only the dtsi file differs from the mainline. Compile tested for all SAMA5 chips for now, and tested on SAMA5D3xek as there is no existing SAMA5D2 board with NAND Flash memory (yet).
