spi: spi-mem: Add driver for NXP FlexSPI controller

2019-01-28T12:27:44Z

- Add driver for NXP FlexSPI host controller (0) What is the FlexSPI controller? FlexSPI is a flexsible SPI host controller which supports two SPI channels and up to 4 external devices. Each channel supports Single/Dual/Quad/Octal mode data transfer (1/2/4/8 bidirectional data lines) i.e. FlexSPI acts as an interface to external devices, maximum 4, each with up to 8 bidirectional data lines. It uses new SPI memory interface of the SPI framework to issue flash memory operations to up to four connected flash devices (2 buses with 2 CS each). (1) Tested this driver with the mtd_debug and JFFS2 filesystem utility on NXP LX2160ARDB and LX2160AQDS targets. LX2160ARDB is having two NOR slave device connected on single bus A i.e. A0 and A1 (CS0 and CS1). LX2160AQDS is having two NOR slave device connected on separate buses one flash on A0 and second on B1 i.e. (CS0 and CS3). Verified this driver on following SPI NOR flashes: Micron, mt35xu512ab, [Read - 1 bit mode] Cypress, s25fl512s, [Read - 1/2/4 bit mode] Signed-off-by: Yogesh Narayan Gaur Reviewed-by: Frieder Schrempf Reviewed-by: Boris Brezillon Tested-by: Ashish Kumar Signed-off-by: Mark Brown

spi: Add a driver for the Freescale/NXP QuadSPI controller

2019-01-07T16:56:24Z

This driver is derived from the SPI NOR driver at mtd/spi-nor/fsl-quadspi.c. It uses the new SPI memory interface of the SPI framework to issue flash memory operations to up to four connected flash chips (2 buses with 2 CS each). The controller does not support generic SPI messages. This patch also disables the build of the "old" driver and reuses its Kconfig option CONFIG_SPI_FSL_QUADSPI to replace it.

spi: Add QuadSPI driver for Atmel SAMA5D2

2018-11-07T13:21:19Z

Kernel contains QSPI driver strongly tied to MTD and nor-flash memory. New spi-mem interface allows usage also other memory types, especially much larger NAND with SPI interface. This driver works as SPI controller and is not related to MTD, however can work with NAND-flash or other peripherals using spi-mem interface.

spi: spi-mem: add stm32 qspi controller

The qspi controller is a specialized communication interface targeting single, dual or quad SPI Flash memories (NOR/NAND). 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 tested on: -NOR: mx66l51235l -NAND: MT29F2G01ABAGD Signed-off-by: Ludovic Barre Signed-off-by: Mark Brown
