I've not got any up to date information about the 2450, but I belive the newer HSPI block is not compatible with the older spi_s3c24xx.c driver. > So my question is my XR20M1172(slave spi) will communicate with hspi or > spi_s3c24xx file because i am registering my slave chip with spi.c file > which is talking with spi_s3c24xx.c file. The registeration of SPI devices is seperate from the registration of the SPI bus master. The SPI bus master is registered from a platform device that attaches the master controller to a SPI bus. The SPI bus is specified in a number passed in to the driver via platform_data supplied when the master is registered. > I am using linux 2.6.21 kernel source. I might be persuaded to do an HSPI driver, but it will be a patch against a much newer kernel, since it will be useful for other devices that are being actively maintained. > Any help will be greatful. > > Regards > > Arjun > ------------------------------------------------------------------------------ > Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day > trial.
