spi: master driver to enable RTC on ICPDAS LP-8841

2016-02-24T04:09:08+00:00

ICP DAS LP-8841 contains a DS-1302 RTC. This driver provides an SPI master which makes the RTC usable. The driver is not supposed to work with anything else. The driver uses the standard MicroWire half-duplex transfer timing. Master output is set on low clock and sensed by the RTC on the rising edge. Master input is set by the RTC on the trailing edge and is sensed by the master on low clock. Signed-off-by: Sergei Ianovich Acked-by: Rob Herring Signed-off-by: Mark Brown

spi: sh-spi, sh-msiof, rspi: Use ARCH_RENESAS

2016-02-18T13:35:07+00:00

Make use of ARCH_RENESAS in place of ARCH_SHMOBILE. This is part of an ongoing process to migrate from ARCH_SHMOBILE to ARCH_RENESAS the motivation for which being that RENESAS seems to be a more appropriate name than SHMOBILE for the majority of Renesas ARM based SoCs.

spi: Allow compile test of bcm2835aux if !GPIOLIB

2016-02-08T13:42:10+00:00

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 of SPI_BCM2835AUX on GPIOLIB if COMPILE_TEST is enabled. Signed-off-by: Geert Uytterhoeven Signed-off-by: Mark Brown

spi: Add Analog Devices AXI SPI Engine controller support

2016-02-05T18:12:57+00:00

This patch adds support for the AXI SPI Engine controller which is a FPGA soft-peripheral which is used in some of Analog Devices' reference designs. The AXI SPI Engine controller is part of the SPI Engine framework[1] and allows memory mapped access to the SPI Engine control bus. This allows it to be used as a general purpose software driven SPI controller. The SPI Engine in addition offers some optional advanced acceleration and offloading capabilities, which are not part of this patch though and will be introduced separately. At the core of the SPI Engine framework is a small sort of co-processor that accepts a command stream and turns the commands into low-level SPI transactions. Communication is done through three memory mapped FIFOs in the register map of the AXI SPI Engine peripheral. One FIFO for the command stream and one each for transmit and receive data. The driver translates a spi_message in a command stream and writes it to the peripheral which executes it asynchronously. This allows it to perform very precise timings which are required for some SPI slave devices to achieve maximum performance (e.g. analog-to-digital and digital-to-analog converters). The execution flow is synchronized to the host system by a special synchronize instruction which generates a interrupt.
