We do have macros for defining command, address, dummy and data cycles. We also have a .dtr flag that implies sampling the bus on both edges, but there are currently no macros enabling it. We might make use of such macros, so let's create: - SPI_MEM_DTR_OP_CMD - SPI_MEM_DTR_OP_ADDR - SPI_MEM_DTR_OP_DUMMY - SPI_MEM_DTR_OP_DATA_OUT - SPI_MEM_DTR_OP_DATA_OUT Signed-off-by: Miquel Raynal <miquel.raynal@bootlin.com> --- include/linux/spi/spi-mem.h | 41 +++++++++++++++++++++++++++++++++++++++++ 1 file changed, 41 insertions(+)
