I have a device use 3-wire spi which are CS,SCK,and a DATA for read/write.( maybe a.s.k.a SISO) The command format like as p.18 in www.newhavendisplay.com/app_notes/NV3035C.pdf The spi-gpio can't register miso and mosi for same GPIO pin. 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@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
