(The driver was posted as a patch some time ago, clearly marked as not ready for mainline. I just did not figure out the correct search term to give the message ID.) Now I am running into problems because the driver uses spi_cs_[de]activate, which is rather useless on coldfire which does automatic cs. Looking through other drivers' code it seems to me that spi_cs_[de]activate was never meant to be called from anybody else but some special SPI drivers that can not aotumatically control cs lines or for systems where SPI is done in software and so setting the appropriate GPIOs is handed over to special board-dependent code. Is this correct, or am I missing something? Regards, Wolfgang
