      "message": "spi: bugfix spi_add_device() with duplicate chipselects\n\nWhen reviewing a recent patch I noticed a potential trouble spot in the\nregistration of new SPI devices.  The SPI master driver is told to set\nthe device up before adding it to the driver model, so that it\u0027s always\nproperly set up when probe() is called.  (This is important, because in\nthe case of inverted chipselects, this device can make the bus misbehave\nuntil it\u0027s properly deselected.  It\u0027s got to be set up even if no driver\nbinds to the device.)\n\nThe trouble spot is that it doesn\u0027t first verify that no other device\nhas been added using that chipselect.  If such a device has been added,\nits configuration gets trashed.  (Fortunately this has not been a common\nerror!)\n\nThe fix here adds an explicit check, and a mutex to protect the relevant\ncritical region.\n\n[akpm@linux-foundation.org: make the lock local to spi_add_device()]\nSigned-off-by: David Brownell \u003cdbrownell@users.sourceforge.net\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

      "message": "spi: split up spi_new_device() to allow two stage registration.\n\nspi_new_device() allocates and registers an spi device all in one swoop.\nIf the driver needs to add extra data to the spi_device before it is\nregistered, then this causes problems.  This is needed for OF device\ntree support so that the SPI device tree helper can add a pointer to\nthe device node after the device is allocated, but before the device\nis registered.  OF aware SPI devices can then retrieve data out of the\ndevice node to populate a platform data structure.\n\nThis patch splits the allocation and registration portions of code out\nof spi_new_device() and creates two new functions; spi_alloc_device()\nand spi_register_device().  spi_new_device() is modified to use the new\nfunctions for allocation and registration.  None of the existing users\nof spi_new_device() should be affected by this change.\n\nDrivers using the new API can forego the use of spi_board_info\nstructure to describe the device layout and populate data into the\nspi_device structure directly.\n\nThis change is in preparation for adding an OF device tree parser to\ngenerate spi_devices based on data in the device tree.\n\nSigned-off-by: Grant Likely \u003cgrant.likely@secretlab.ca\u003e\nAcked-by: David Brownell \u003cdbrownell@users.sourceforge.net\u003e\n"

Since it is a pointer copy, the new spi_device\nremains dependent on the spi_board_info structure after the new spi_device\nis registered (no other fields in spi_device directly depend on the\nspi_board_info structure; all of the other data is copied).\n\nThis causes a problem when dynamically propulating the list of attached\nSPI devices.  For example, in arch/powerpc, the list of SPI devices can be\npopulated from data in the device tree.  With the current code, the device\ntree adapter must kmalloc() a new spi_board_info structure for each new\nSPI device it finds in the device tree, and there is no simple mechanism\nin place for keeping track of these allocations.\n\nThis patch changes modalias from a \u0027const char *\u0027 to a fixed char array.\nBy copying the modalias string instead of referencing it, the dependency\non the spi_board_info structure is eliminated and an outside caller does\nnot need to maintain a separate spi_board_info allocation for each device.\n\nIf searched through the code to the best of my ability for any references\nto modalias which may be affected by this change and haven\u0027t found\nanything.

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"
