Thanks for your patch!
Please CC linux-spi on SPI patches.
Thanks, I'll do it next time!
static int qspi_transfer_out_in(struct rspi_data *rspi,
struct spi_transfer *xfer)
{
qspi_receive_init(rspi);
-
- return rspi_common_transfer(rspi, xfer);
+ return qspi_trigger_transfer_out_int(rspi, xfer->tx_buf,
+ xfer->rx_buf, xfer->len);
So this will always use PIO mode, even if DMA is available?
Thanks, I am going to make a new version with a DMA support.
Best Regards,
Jinso/Cao Minh Hiep.
