From: Ludovic Barre <ludovic.ba...@st.com> This patch set adds a SPI-NOR driver for stm32 QSPI controller. 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 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 | 45 ++ drivers/mtd/spi-nor/Kconfig | 7 + drivers/mtd/spi-nor/Makefile | 1 + drivers/mtd/spi-nor/stm32-quadspi.c | 679 +++++++++++++++++++++ 4 files changed, 732 insertions(+) create mode 100644 Documentation/devicetree/bindings/mtd/stm32-quadspi.txt create mode 100644 drivers/mtd/spi-nor/stm32-quadspi.c -- 2.7.4
