HI,
I want to know how change this for ppp for uart?
/* modem status interrupt bits are undefined
after reset,and the hardware do not support
DSRMIS,DCDMIS and RIMIS bit,so we should ingore
them when they are pending. */
if (istat & (BM_UARTAPP_INTR_ABDIS
| BM_UARTAPP_INTR_OEIS
| BM_UARTAPP_INTR_BEIS
| BM_UARTAPP_INTR_PEIS
| BM_UARTAPP_INTR_FEIS
| BM_UARTAPP_INTR_RTIS
| BM_UARTAPP_INTR_TXIS
| BM_UARTAPP_INTR_RXIS
| BM_UARTAPP_INTR_CTSMIS)) {
dev_info(s->dev, "Unhandled status %x\n", istat);
}
__raw_writel(istatus & (BM_UARTAPP_INTR_ABDIS
| BM_UARTAPP_INTR_OEIS
| BM_UARTAPP_INTR_BEIS
| BM_UARTAPP_INTR_PEIS
| BM_UARTAPP_INTR_FEIS
| BM_UARTAPP_INTR_RTIS
| BM_UARTAPP_INTR_TXIS
| BM_UARTAPP_INTR_RXIS
| BM_UARTAPP_INTR_DSRMIS
| BM_UARTAPP_INTR_DCDMIS
| BM_UARTAPP_INTR_CTSMIS
| BM_UARTAPP_INTR_RIMIS),
s->port.membase + HW_UARTAPP_INTR_CLR);
when i use uart to ppp ,it always print mxs-auart mxs-auart.0: Unhandled status 520080 !
when i disable this part ,it works ok.
thanks !
Hi
this is just warning and seems can be safely ignored.
Best regards
igor
