The spi-imx driver supports both master and slave modes, so update the help text to make it more generic. Signed-off-by: Fabio Estevam Signed-off-by: Mark Brown

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: ath79: Enable support for compile test

2019-01-17T12:34:47Z

To allow building this driver in compile test we need to remove all dependency on headers from arch/mips/include. To allow this we explicitly define all the registers locally instead of using ar71xx_regs.h and we move the platform data struct definition to include/linux/platform_data/spi-ath79.h.

spi: ath79: Simplify ath79_spi_chipselect()

2019-01-17T12:34:39Z

First of all this callback was slightly misused to setup the clock polarity at the beginning of a transfer. Beside being at the wrong place, it is also useless as only SPI mode 1 is supported. Instead just make sure the base value used for IOC is suitable to start a transfer by clearing the clock and data bits during the controller setup. This also remove the last direct usage of the GPIO API, so we can remove the direct dependency on GPIOLIB. Signed-off-by: Alban Bedel Signed-off-by: Mark Brown

spi: add cpu details to fsl-dspi Kconfig help

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.

mtd: atmel-quadspi: disallow building on ebsa110

2018-12-11T01:15:11Z

I ran into a link-time error with the atmel-quadspi driver on the EBSA110 platform: drivers/mtd/built-in.o: In function `atmel_qspi_run_command': :(.text+0x1ee3c): undefined reference to `_memcpy_toio' :(.text+0x1ee48): undefined reference to `_memcpy_fromio' The problem is that _memcpy_toio/_memcpy_fromio are not available on that platform, and we have to prevent building the driver there. In case we want to backport this to older kernels: between linux-4.8 and linux-4.20, the Kconfig entry was in drivers/mtd/spi-nor/Kconfig but had the same problem.
