It is a specialized SPI interface for serial Flash devices. It supports 1 or 2 Flash device with single, dual and quad SPI Flash memories. It can operate in any of the following modes: -indirect mode: all the operations are performed using the quadspi registers -read memory-mapped mode: the external Flash memory is mapped to the microcontroller address space and is seen by the system as if it was an internal memory Changes in v4: -unsigned bitfields: (1U << 8) -remove "mtd->priv" -error management: issue on no mtd device registered -remove braces in stm32_qspi_mtd_free Changes in v3: -dt-bindings: qspi_mm not optional -dt-bindings: see ../spi/spi-bus.txt -dt-bindings: spi@... -cmd flat struct -ratelimit -macro to avoid hard value "25" Changes in v2: -awful construct: s/u32/u8 -add define for timeout -Use a helper variable -add comment on "stm32 qspi controller fsize issue Ludovic Barre (2): dt-bindings: Document the STM32 QSPI bindings mtd: spi-nor: add driver for STM32 quad spi flash controller .../devicetree/bindings/mtd/stm32-quadspi.txt | 43 ++ drivers/mtd/spi-nor/Kconfig | 7 + drivers/mtd/spi-nor/Makefile | 1 + drivers/mtd/spi-nor/stm32-quadspi.c | 694 +++++++++++++++++++++ 4 files changed, 745 insertions(+) create mode 100644 Documentation/devicetree/bindings/mtd/stm32-quadspi.txt create mode 100644 drivers/mtd/spi-nor/stm32-quadspi.c -- 2.7.4
