Also I traced SPI-3WIRE flag it seems only support half 3-wire which only write or only read but share ping Does current driver can support this kind of 3wire spi format? Or I need to do some modify to support this 3-wire spi -- To unsubscribe from this list: send the line "unsubscribe linux-spi" in the body of a message to majordomo-u79uwXL29TY76Z2rM5mHXA@public.gmane.org More majordomo info at http://vger.kernel.org/majordomo-info.html
