2015-10-23spi/bcm63xx: move register definitions into the driverJonas Gorski1-1/+1
Move all register definitions and structs into the driver. This allows us dropping the platform_data struct and drop any arch specific includes. Make use of different device names to identify the version of the block we have. Since we now have full control over the message width, we can drop the size check, which was broken anyway, since it never set ret to any error code. Also since we now have no arch depedendent resources, we can now allow compiling it for any arch, hidden behind COMPILE_TEST.

2015-10-07spi: bcm2835aux: add bcm2835 auxiliary spi device driverMartin Sperl1-0/+11
The bcm2835 has 2 auxiliary spi bus masters spi1 and spi2. This implements the driver to enable these devices. The driver does not implement native chip-selects but uses the aribtrary GPIO-chip-selects provided by the spi-chipselect. Note that this driver relies on the fact that the clock is implemented by the clk-bcm2835-aux driver, which enables/disables the HW block when requesting/releasing the clock.

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.

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>
