Hi,
What does these two lines in DTS File.
Can u let me know what this suppose to mean
scc@a00 {
........
rx-clock = <1>;
tx-clock = <1>;
........
interrupts = <1e 3>;
interrupt-parent = <&Cpm_pic>;
}
Actually where can we get a better documentation for the DTS File? If
you have any reference please let me know. Thanks A Lot.
Regards,
Vignesh

These indicate which baud rate generator the serial port is attached to.

These indicate that the serial port uses interrupt 0x1e on the CPM PIC.
