Hi all, this series of patches adds support to the Atmel QSPI controller. It was tested on a sama5d2 xplained board + Macronix mx25l25673g QSPI memory.
The driver limits its support of Quad SPI memories to the SPI 1-1-4 protocol for Fast Read operations and SPI 1-1-1 protocol for all other commands. The series is based on next-20160609 Best regards, Cyrille Cyrille Pitchen (2): Documentation: atmel-quadspi: add binding file for Atmel QSPI driver mtd: atmel-quadspi: add driver for Atmel QSPI controller .../devicetree/bindings/mtd/atmel-quadspi.txt | 32 + drivers/mtd/spi-nor/Kconfig | 9 + drivers/mtd/spi-nor/Makefile | 1 + drivers/mtd/spi-nor/atmel-quadspi.c | 741 +++++++++++++++++++++ 4 files changed, 783 insertions(+) create mode 100644 Documentation/devicetree/bindings/mtd/atmel-quadspi.txt create mode 100644 drivers/mtd/spi-nor/atmel-quadspi.c -- 1.8.2.2
