Add flags for Octal I/O data transfer Required for the SPI controller which can do data transfer (TX/RX) on 8 data lines e.g. NXP FlexSPI controller. SPI_TX_OCTAL: transmit with 8 wires SPI_RX_OCTAL: receive with 8 wires Signed-off-by: Yogesh Gaur <redacted> --- include/linux/spi/spi.h | 2 ++ 1 file changed, 2 insertions(+)
