[vinothkumars]

Hi,

I had the issue I unable to find the device entry for LPUAR1 - ttyLP1.

Here is the debug message,

[ 1.732363] 5a070000.serial: ttyLP1 at MMIO 0x5a070010 (irq = 65, base_baud = 5000000) is a FSL_LPUART
[ 1.741833] serial serial0: tty port ttyLP1 registered

Hi All,

finally, I found the fix. This uart interface is allocated to chipset by default in dts.
