Hi. Is it legal to use zero for 'len' field of struct spi_transfer? I mean, len=0, tx_buf=rx_buf=NULL, delay_usecs!=0.
Some SPI devices need slightly long delay before first CLK edge after CS assertion. To achieve this, I think inserting using a zero length transfer before real transfers. But it seems some drivers do not handle this case properly. Is this driver's bug, or we need additional delay field in struct spi_device for such case? --- Atsushi Nemoto -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
