OK it was not such a big deal, but many many thanks for fixing this up! :-) > Except in case of callback specification (dma_filter()), you need to > provide platform data.

This is very likely because the clock tree has a name like "dev:ssp0" encoded for this device, and if you don't nail it down like that the device name will be the same as the node in your device tree and then clock lookup will fail. The "real fix" is to convert the clock drivers to use device tree so the drivers can just refer to the phandles to figure out what clock node they need. Along with the DMA channel mapping this is one of the major roadblocks to finalizing the device tree adoptions. > When we have sorted out this driver change (please check the new pl022 > specific dt property names!), I will provide patches for arm-soc to > actually use this new interface via dts files. OK cool I guess you will do this for the LPC32xx? Or are you testing this on some other platforms?
