Hi, Im experimenting the spi interface on a RT5350 target. Its spi driver set the interface as half duplex
master->dev.of_node = pdev->dev.of_node; master->mode_bits = RT2880_SPI_MODE_BITS; master->bits_per_word_mask = SPI_BPW_MASK(8); master->min_speed_hz = clk_get_rate(clk) / 128; master->max_speed_hz = clk_get_rate(clk) / 2; master->flags = SPI_MASTER_HALF_DUPLEX; master->setup = rt2880_spi_setup; master->prepare_message = rt2880_spi_prepare_message; master->set_cs = rt2880_spi_set_cs; master->transfer_one = rt2880_spi_transfer_one, but from the datasheet it seems that the device is full duplex capable. There are some reason to set the driver in this way? Thanks, bye. _______________________________________________ Lede-dev mailing list Lede-dev@lists.infradead.org http://lists.infradead.org/mailman/listinfo/lede-dev
