* SPI driver hotplug/coldplug fixesDavid Brownell2007-08-311-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Blackfin SPI: cleanup according to David Brownell's reviewBryan Wu2007-05-211-72/+80
| | | | | | | | | | a) platorm_driver_probe(...) instead of platform_driver_register(&driver); b) set bfin_spi_enable and bfin_spi_disable static c) Why is the width flag a u32? d) maybe use dev_dbg() instead of pr_debug() Signed-off-by: Bryan Wu <bryan.wu@analog.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
