2009-06-18spi: move more spi_setup() functionality into coreDavid Brownell1-9/+3
Move some common spi_setup() error checks into the SPI framework from the spi_master controller drivers: - Add a new "mode_bits" field to spi_master - Use that in spi_setup to validate the spi->mode value being requested. Setting this new field is now mandatory for any controller supporting more than vanilla SPI_MODE_0. - Update all spi_master drivers to: * Initialize that field * Remove current spi_setup() checks using that value. This is a net minor code shrink.

2009-06-18spi: move common spi_setup() functionality into coreDavid Brownell1-6/+0
Start moving some spi_setup() functionality into the SPI core from the various spi_master controller drivers: - Make that function stop being an inline; - Move two common idioms from drivers into that new function: * Default bits_per_word to 8 if that field isn't set * Issue a standardized dev_dbg() message This is a net minor source code shrink, and supports enhancments found in some follow-up patches.

2009-03-11powerpc/virtex/spi: Xilinx SPI driver not releasing memoryJohn Linn1-2/+7
The driver was not releasing memory when it was removed or when there was a failure during probe. This fixes it. Signed-off-by: John Linn <john.linn@xilinx.com> Acked-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
2009-01-09Xilinx: SPI: updated driver for device treeJohn Linn1-56/+81
The driver was updated to use the device tree rather than the platform data. Signed-off-by: John Linn <john.linn@xilinx.com>

2008-04-11spi: fix platform driver hotplug/coldplugKay Sievers1-0/+3
Since 43cc71eed1250755986da4c0f9898f9a635cb3bf, the platform modalias is prefixed with "platform:". Add MODULE_ALIAS() to the hotpluggable SPI platform drivers, to allow module auto loading.

2007-08-31SPI driver hotplug/coldplug fixesDavid Brownell1-1/+1
Update various SPI drivers so they properly support - coldplug through "modprobe $(cat /sys/devices/.../modalias)" - hotplug through "modprobe $(MODALIAS)" The basic rule for platform, SPI, and (new style) I2C drivers is just to make sure that modprobing the driver name works. In this case, all the relevant drivers are platform drivers, and this patch either (a) Changes the driver name, if no in-tree code would break; this is simpler and thus preferable in the long term. (b) Adds MODULE_ALIAS directives, when in-tree platforms declare devices using the current driver name; less desirable. Most systems will link SPI controller drivers statically, but there's no point in being needlessly broken.
