[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 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.

Now that the generic ARM implementation defines mb() to mean (at least) dsb(), it is appropriate to switch back to the generic kernel version of the barriers. This is also needed for correctness on certain targets (such as 7x27) where dsb() is insufficient and other operations (such as outer cache sync or writing to strongly-ordered memory) are required to ensure proper I/O operations ordering. In some cases, remove explicit calls to outer_sync following a barrier since the barrier will now have an explicit outer_sync call.

The controller also supports other peripheral protocols, however its SPI functionality is very similar to previous SPI core, supported by spi_qsd. Therefore the same driver is being utilized with some register address modification and minor flow change.

This protects the statistics from accidentally being access from another context at the same time.

This graceful closure waits for all the pending transfers to finish or timeout, while not allowing new ones to queue up. This allows correct handling of all the resources involved in a transfer before suspend.

The driver is SPI master, and allows slave connections. Current version of the driver supports FIFO and DM modes chosen upon the message size. The driver also supports loopback mode which can be used for testing purposes. This is a squashed version of all the MSM SPI driver changes on the QuIC MSM 2.6.29 kernel which can be found at www.codeaurora.org. It also contains all relevant adaptations to SPI core changes in 2.6.32 kernel. https://www.codeaurora.org/gitweb/quic/la/?p=kernel/msm.git;a=blob;f=drivers/spi/spi_qsd.c;h=1c8e3ec727b29040648ef9a4949396f7109528ae;hb=refs/heads/android-msm-2.6.29b Change-Id: Ibc1e71deb662af87deed77f10dcc8a3a46a8f012 Signed-off-by: Lena Salman <esalman@qualcomm.com> Signed-off-by: David Brown <davidb@codeaurora.org>
