Hello, this is the reworked series to address the handshaking problems I saw. Among others it made my i.MX25 stuck when the other side toggles DCD. The first 4 patches are fixes that I'd like to see in 4.6-rcX, the last two patches are merge window material. Best regards Uwe Uwe Kleine-König (6): serial: imx: fix polarity of RI serial: imx: let irq handler return IRQ_NONE if no event was handled serial: imx: make sure unhandled irqs are disabled serial: imx: only count 0->1 transitions for RNG serial: imx: reorder functions to simplify next patch serial: imx: implement DSR irq handling for DTE mode drivers/tty/serial/imx.c | 156 ++++++++++++++++++++++++++++++----------------- 1 file changed, 100 insertions(+), 56 deletions(-) -- 2.7.0 -- To unsubscribe from this list: send the line "unsubscribe linux-serial" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
