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. Based on linux-mtd-next, commit ed4eeba7338bb123090f1c8b208f64d8184a896d See revision 2 to apply on the Atmel Linux 4.1 branch. Compile tested for sama5_defconfig, and tested on SAMA5D3xek as there is no existing SAMA5D2 board with NAND Flash memory (yet).
