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
