2008-04-11spi: fix platform driver hotplug/coldplugKay Sievers1-0/+2
Since 43cc71eed1250755986da4c0f9898f9a635cb3bf, the platform modalias is prefixed with "platform:". Add MODULE_ALIAS() to the hotpluggable SPI platform drivers, to allow module auto loading.

2008-02-06spi: s3c drivers shouldn't care about spi_board_infoDavid Brownell1-12/+0
The two S3C SPI master drivers got merged without much review, so I just noticed that they're doing something that the SPI core code is responsible for, rather than any adapter driver: they try to register SPI devices. This removes that support from those drivers so they act normally. Interestingly, none of the current boards are affected. So it's a net code shrink with no loss of functionality.

2007-11-29spi: S3C2410: add bus number to SPI GPIO driverDavid Brownell1-0/+1
Allow passing a bus number through the platform data for the S3C2410 SPI GPIO driver. This is needed to support multiple SPI busses.

2007-11-29S3C24XX: ensure we only configure valid GPIOsBen Dooks1-7/+13
If we specify an GPIO which cannot be used for the purpose, then assume that the GPIO is not to be used and do not try and configure it. This can be the case where the SPI bus is TX only.

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.

2006-12-30[PATCH] spi_s3c24xx_gpio: use right headerArnaud Patard (Rtp1-1/+1
Russel King recently reminded us that one shouldn't use asm/arch/hardware.h but one should use asm/hardware.h. Unfortunately, the spi_s3c24xx_gpio driver is using the wrong header. This patch is fixing that.
