Add support for sending and receiving the least significant bit first for the spi_bitbang driver. This driver can now be used with SPI_TRANFER_LSB flag. Signed-off-by: Michal Morsisko <[email protected]>
Prevent the driver from perfroming transfer when SPI_LINES_OCTAL flag is specified, as this driver supports only SPI_LINES_DUAL for now. Signed-off-by: Michal Morsisko <[email protected]>
