This patch set adds a SPI-NOR driver for the NXP SPI Flash (SPIFI) controller that can be found on newer NXP MCUs. For example on the LPC18xx and LPC43xx familiy. NXP SPIFI is a specialized SPI interface for serial Flash devices. It supports one Flash device with 1-, 2- and 4-bits width in SPI mode 0 or 3. The controller operates in either command or memory mode. In memory mode the Flash is made accessible for the CPU as normal memory. This version fix a bug in the write function discovered during testing with JFFS2. Changes since v3: - fix bug in write function - rebase on 4.2-rc1 Changes since v2: - default to auto detection unless chip is specified - update doc with reference to jedec,spi-nor.txt Changes since v1: - use readb_poll_timeout instead of open coding - cache current mode (memory/command) - depend on HAS_IOMEM - removed stray white space - removed leftover debug print Joachim Eastwood (2): mtd: spi-nor: add driver for NXP SPI Flash Interface (SPIFI) doc: dt: add documentation for nxp,lpc1773-spifi .../devicetree/bindings/mtd/nxp-spifi.txt | 58 +++ drivers/mtd/spi-nor/Kconfig | 11 + drivers/mtd/spi-nor/Makefile | 1 + drivers/mtd/spi-nor/nxp-spifi.c | 494 +++++++++++++++++++++ 4 files changed, 564 insertions(+) create mode 100644 Documentation/devicetree/bindings/mtd/nxp-spifi.txt create mode 100644 drivers/mtd/spi-nor/nxp-spifi.c -- 1.8.0 -- 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
