When enabling the uart4 node in the Pine64's Device Tree, there is no /dev/ttyS4 device available. No related error messages apart from deferred pinctrl probing. UART3 works fine as /dev/ttyS3. Workaround: none (use a different UART if you can) I am guessing that limiting us to four 8250 UARTs causes further UARTs to be silently ignored: CONFIG_SERIAL_8250_NR_UARTS=4 CONFIG_SERIAL_8250_RUNTIME_UARTS=4 We should probably revise those numbers.
