See Documentation/spi/spidev ... but be aware that even the latest code probably still has issues with nCS0 because of hardware errata on the rm9200 chips. There are some SPI patches due to move upstream that should help that a bit, but I don't think there's a complete solution yet ... short of using the bitbang code I reposted to the ARM list within the last month or so. (ALSO: don't cross-post to the ARM list.) ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
