[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.

spi/rockchip: add driver for Rockchip RK3xxx SoCs integrated SPI In order to facilitate understanding, rockchip SPI controller IP design looks similar in its registers to designware. But IC implementation is different from designware, So we need a dedicated driver for Rockchip RK3XXX SoCs integrated SPI. The main differences: - dma request line: rockchip SPI controller have two DMA request line for tx and rx. - Register offset: RK3288 dw SPI_CTRLR0 0x0000 0x0000 SPI_CTRLR1 0x0004 0x0004 SPI_SSIENR 0x0008 0x0008 SPI_MWCR NONE 0x000c SPI_SER 0x000c 0x0010 SPI_BAUDR 0x0010 0x0014 SPI_TXFTLR 0x0014 0x0018 SPI_RXFTLR 0x0018 0x001c SPI_TXFLR 0x001c 0x0020 SPI_RXFLR 0x0020 0x0024 SPI_SR 0x0024 0x0028 SPI_IPR 0x0028 NONE SPI_IMR 0x002c 0x002c SPI_ISR 0x0030 0x0030 SPI_RISR 0x0034 0x0034 SPI_TXOICR NONE 0x0038 SPI_RXOICR NONE 0x003c SPI_RXUICR NONE 0x0040 SPI_MSTICR NONE 0x0044 SPI_ICR 0x0038 0x0048 SPI_DMACR 0x003c 0x004c SPI_DMATDLR 0x0040 0x0050 SPI_DMARDLR 0x0044 0x0054 SPI_TXDR 0x0400 NONE SPI_RXDR 0x0800 NONE SPI_IDR NONE 0x0058 SPI_VERSION NONE 0x005c SPI_DR NONE 0x0060 - register configuration: such as SPI_CTRLRO in rockchip SPI controller: cr0 = (CR0_BHT_8BIT << CR0_BHT_OFFSET) | (CR0_SSD_ONE << CR0_SSD_OFFSET); cr0 |= (rs->n_bytes << CR0_DFS_OFFSET); cr0 |= ((rs->mode & 0x3) << CR0_SCPH_OFFSET); cr0 |= (rs->tmode << CR0_XFM_OFFSET); cr0 |= (rs->type << CR0_FRF_OFFSET); For more information, see RK3288 chip manual. - Wait for idle: Must ensure that the FIFO data has been sent out before the next transfer.
