[PATCH] spi: simple SPI framework This is the core of a small SPI framework, implementing the model of a queue of messages which complete asynchronously (with thin synchronous wrappers on top). - It's still less than 2KB of ".text" (ARM). If there's got to be a mid-layer for something so simple, that's the right size budget. :) - The guts use board-specific SPI device tables to build the driver model tree. (Hardware probing is rarely an option.) - This version of Kconfig includes no drivers. At this writing there are two known master controller drivers (PXA/SSP, OMAP MicroWire) and three protocol drivers (CS8415a, ADS7846, DataFlash) with LKML mentions of other drivers in development. - No userspace API. There are several implementations to compare. Implement them like any other driver, and bind them with sysfs. The changes from last version posted to LKML (on 11-Nov-2005) are minor, and include: - One bugfix (removes a FIXME), with the visible effect of making device names be "spiB.C" where B is the bus number and C is the chipselect. - The "caller provides DMA mappings" mechanism now has kerneldoc, for DMA drivers that want to be fancy. - Hey, the framework init can be subsys_init. Even though board init logic fires earlier, at arch_init ... since the framework init is for driver support, and the board init support uses static init. - Various additional spec/doc clarifications based on discussions with other folk. It adds a brief "thank you" at the end, for folk who've helped nudge this framework into existence. As I've said before, I think that "protocol tweaking" is the main support that this driver framework will need to evolve. From: Mark Underwood <basicmark@yahoo.com> Update the SPI framework to remove a potential priority inversion case by reverting to kmalloc if the pre-allocated DMA-safe buffer isn't available.

spi: Add Analog Devices AXI SPI Engine controller support 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.

spi: add driver for BCM2835 The BCM2835 contains two forms of SPI master controller (one known simply as SPI0, and the other known as the "Universal SPI Master", in the auxilliary block) and one form of SPI slave controller. This patch adds support for the SPI0 controller. This driver is taken from Chris Boot's repository at git://github.com/bootc/linux.git rpi-linear as of commit 6de2905 "spi-bcm2708: fix printf with spurious %s". In the first SPI-related commit there, Chris wrote: Thanks to csoutreach / A Robinson for his driver which I used as an inspiration. You can find his version here: http://piface.openlx.org.uk/raspberry-pi-spi-kernel-driver-available-for Changes made during upstreaming: * Renamed bcm2708 to bcm2835 as per upstream naming for this SoC. * Removed support for brcm,realtime property. * Increased transfer timeout to 30 seconds. * Return IRQ_NONE from the IRQ handler if no interrupt was handled. * Disable TA (Transfer Active) and clear FIFOs on a transfer timeout. * Wrote device tree binding documentation. * Request unnamed clock rather than "sys_pclk"; the DT will provide the correct clock. * Assume that tfr->speed_hz and tfr->bits_per_word are always set in bcm2835_spi_start_transfer(), bcm2835_spi_transfer_one(), so no need to check spi->speed_hz or tft->bits_per_word. * Re-ordered probe() to remove the need for temporary variables. * Call clk_disable_unprepare() rather than just clk_unprepare() on probe() failure. * Don't use devm_request_irq(), to ensure that the IRQ doesn't fire after we've torn down the device, but not unhooked the IRQ. * Moved probe()'s call to clk_prepare_enable() so we can be sure the clock is enabled if the IRQ handler fires immediately. * Remove redundant checks from bcm2835_spi_check_transfer() and bcm2835_spi_setup(). * Re-ordered IRQ handler to check for RXR before DONE. Added comments to ISR. * Removed empty prepare/unprepare implementations. * Removed use of devinit/devexit. * Added BCM2835_ prefix to defines.

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.

spi/qspi: Add qspi flash controller The patch add basic support for the quad spi controller. QSPI is a kind of spi module that allows single, dual and quad read access to external spi devices. The module has a memory mapped interface which provide direct interface for accessing data form external spi devices. The patch will configure controller clocks, device control register and for defining low level transfer apis which will be used by the spi framework to transfer data to the slave spi device(flash in this case). Test details: ------------- Tested this on dra7 board. Test1: Ran mtd_stesstest for 40000 iterations. - All iterations went through without failure. Test2: Use mtd utilities: - flash_erase to erase the flash device - mtd_debug read to read data back. - mtd_debug write to write to the data flash. diff between the write and read data shows zero.

spi/pxa2xx: break out the private DMA API usage into a separate file The PXA SPI driver uses PXA platform specific private DMA implementation which does not work on non-PXA platforms. In order to use this driver on other platforms we break out the private DMA implementation into a separate file that gets compiled only when CONFIG_SPI_PXA2XX_PXADMA is set. The DMA functions are stubbed out if there is no DMA implementation selected (i.e we are building on non-PXA platform). While we are there we can kill the dummy DMA bits in pxa2xx_spi.h as they are not needed anymore for CE4100. Once this is done we can add the generic DMA engine support to the driver that allows usage of any DMA controller that implements DMA engine API.
