      "message": "[PATCH] spi: add spi_bitbang driver\n\nThis adds a bitbanging spi master, hooking up to board/adapter-specific glue\ncode which knows how to set and read the signals (gpios etc).\n\nThis code kicks in after the glue code creates a platform_device with the\nright platform_data.  That data includes I/O loops, which will usually\ncome from expanding an inline function (provided in the header).  One goal\nis that the I/O loops should be easily optimized down to a few GPIO register\naccesses, in common cases, for speed and minimized overhead.\n\nThis understands all the currently defined protocol tweaking options in the\nSPI framework, and might eventually serve as as reference implementation.\n\n  - different word sizes (1..32 bits)\n  - differing clock rates\n  - SPI modes differing by CPOL (affecting chip select and I/O loops)\n  - SPI modes differing by CPHA (affecting I/O loops)\n  - delays (usecs) after transfers\n  - temporarily deselecting chips in mid-transfer\n\nA lot of hardware could work with this framework, though common types of\ncontroller can\u0027t reach peak performance without switching to a driver\nstructure that supports pipelining of transfers (e.g.  DMA queues) and maybe\ncontrollers (e.g.  IRQ driven).\n\nSigned-off-by: David Brownell \u003cdbrownell@users.sourceforge.net\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@suse.de\u003e\n"

      "message": "[PATCH] spi: simple SPI framework\n\nThis is the core of a small SPI framework, implementing the model of a\nqueue of messages which complete asynchronously (with thin synchronous\nwrappers on top).\n\n  - It\u0027s still less than 2KB of \".text\" (ARM).  If there\u0027s got to be a\n    mid-layer for something so simple, that\u0027s the right size budget.  :)\n\n  - The guts use board-specific SPI device tables to build the driver\n    model tree.  (Hardware probing is rarely an option.)\n\n  - This version of Kconfig includes no drivers.  At this writing there\n    are two known master controller drivers (PXA/SSP, OMAP MicroWire)\n    and three protocol drivers (CS8415a, ADS7846, DataFlash) with LKML\n    mentions of other drivers in development.\n\n  - No userspace API.  There are several implementations to compare.\n    Implement them like any other driver, and bind them with sysfs.\n\nThe changes from last version posted to LKML (on 11-Nov-2005) are minor,\nand include:\n\n  - One bugfix (removes a FIXME), with the visible effect of making device\n    names be \"spiB.C\" where B is the bus number and C is the chipselect.\n\n  - The \"caller provides DMA mappings\" mechanism now has kerneldoc, for\n    DMA drivers that want to be fancy.\n\n  - Hey, the framework init can be subsys_init.  Even though board init\n    logic fires earlier, at arch_init ... since the framework init is\n    for driver support, and the board init support uses static init.\n\n  - Various additional spec/doc clarifications based on discussions\n    with other folk.  It adds a brief \"thank you\" at the end, for folk\n    who\u0027ve helped nudge this framework into existence.\n\nAs I\u0027ve said before, I think that \"protocol tweaking\" is the main support\nthat this driver framework will need to evolve.\n\nFrom: Mark Underwood \u003cbasicmark@yahoo.com\u003e\n\n  Update the SPI framework to remove a potential priority inversion case by\n  reverting to kmalloc if the pre-allocated DMA-safe buffer isn\u0027t available.\n\nSigned-off-by: David Brownell \u003cdbrownell@users.sourceforge.net\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@suse.de\u003e\n"
