2015-06-09spi: spi-pxa2xx: remove legacy PXA DMA bitsDaniel Mack1-8/+1
Generic DMA support was already implemented by commit cd7bed003404 ("spi/pxa2xx: break out the private DMA API usage into a separate file") which moved all the legacy PXA DMA implementation code into its own file. With generic DMA available for PXA, we can now just trash this file.

2015-05-06spi: Allow compile test of GPIO consumers if !GPIOLIBGeert Uytterhoeven1-2/+2
The GPIO subsystem provides dummy GPIO consumer functions if GPIOLIB is not enabled. Hence drivers that depend on GPIOLIB, but use GPIO consumer functionality only, can still be compiled if GPIOLIB is not enabled. Relax the dependency on GPIOLIB if COMPILE_TEST is enabled, where appropriate. Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org> Signed-off-by: Mark Brown <broonie@kernel.org>

2015-04-18spi: Add SPI driver for Mikrotik RB4xx series boardsBert Vermeulen1-0/+6
This driver mediates access between the connected CPLD and other devices on the bus. The m25p80-compatible boot flash and (some models) MMC use regular SPI, bitbanged as required by the SoC. However the SPI-connected CPLD has a two-wire mode, in which two bits are transferred per SPI clock cycle. The second bit is transmitted with the SoC's CS2 pin.

This is a driver for the Amlogic Meson SPIFC (SPI flash controller), which is one of the two SPI controllers available on the SoC. It doesn't support DMA and has a 64-byte unified transmit/receive buffer. The device is optimized for interfacing with SPI NOR memories and allows the execution of standard operations such as read, page program, sector erase, etc. in a simplified way, toggling a bit in a dedicated register. The driver doesn't use those predefined commands and relies only on custom transfers. Signed-off-by: Beniamino Galvani <b.galvani@gmail.com> Signed-off-by: Mark Brown <broonie@kernel.org>

2014-05-16spi/topcliff-pch: Fix Kconfig dependenciesJean Delvare1-1/+1
The spi-topcliff-pch driver is for a companion chip to the Intel Atom E600 series processors. These are 32-bit x86 processors so the driver is only needed on X86_32. Add COMPILE_TEST as an alternative, so that the driver can still be build-tested elsewhere. Signed-off-by: Jean Delvare <jdelvare@suse.de> Signed-off-by: Mark Brown <broonie@linaro.org>
