| * spi: spi_s3c24xx must initialize num_chipselectBen Dooks2008-04-151-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | The SPI core now expects num_chipselect to be set correctly as due to added checks on the chip being selected before an transfer is allowed. This patch adds a num_cs field to the platform data which needs to be set correctly before adding the SPI platform device.

* | [ARM] 4987/1: S3C24XX: Ensure watchdog reset initiated from cached code.Ben Dooks2008-04-172-45/+65
| | | | | | | | | | | | | | | | | | | | | | | | | | | | There seems to be some problem with at-least the S3C2440 and bus traffic during an reset. It is unlikely, but still possible that the system will hang in such a way that the watchdog cannot get the system out of the state it is in. Change to making the code that calls the watchdog reset run from cached memory so that instruction fetches have quiesced before the watchdog fires.

* spi: s3c drivers shouldn't care about spi_board_infoDavid Brownell2008-02-062-12/+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.
