It seems like the rough idea is, You may loot at drivers/spi/spi_s3c64xx.c in Grant Likely's tree. It doesn't put limit on the number of CS and not even on whether the CS mechanism is simple GPIO toggling(though the callback type is defined to match gpio_set_value). For platform side of it, you need to look in to Ben Dooks' tree. hth -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
