On my non-DT s3c64xx system I get this when trying to use SPI for the first time:
Could you clarify first time? Does it work on further retries?
No, the system appears to lock up fairly solidly - I suspect poor error handling in the SPI driver.

though I haven't yet tried your clock patches (there were some conficts that I didn't get round to picking up yet).
This shouldn't really matter, as long as the pl080 drivers probes correctly.
Indeed, I was wondering if it was failing to probe due to not getting its clocks though since that's another area you've been actively working on.
