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. Base on linux-mtd-next, commit 15c0be7bec002f9a529dd0966d0db96dde176fd0 See previous revisions 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). V3 -> V2: - Rebase on linux-mtd-next - Skip patches already in the tree V2 -> V1: - Rebase on v4.4 - Use of_device_get_match_data - Split message cleanup - Reword a small part of the atmel_nand device tree binding - Use 'caps' for all private data structures RFC -> V1: - Split the support of 32-bit ECC on SAMA5D2 in two commits - Fix the missing ECC strength configuration code Romain Izard (5): mtd: atmel_nand: Support variable RB_EDGE interrupts dt-bindings: atmel_nand: Reword the documenation mtd: atmel_nand: Support PMECC on SAMA5D2 mtd: atmel_nand: Support 32-bit ECC strength ARM: at91/dt: sama5d2: add nand0 and nfc0 nodes .../devicetree/bindings/mtd/atmel-nand.txt | 31 +++++---- arch/arm/boot/dts/sama5d2.dtsi | 38 +++++++++++ drivers/mtd/nand/atmel_nand.c | 77 ++++++++++++++++++---- drivers/mtd/nand/atmel_nand_ecc.h | 9 ++- drivers/mtd/nand/atmel_nand_nfc.h | 3 +- 5 files changed, 131 insertions(+), 27 deletions(-) -- 2.5.0 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
