[PATCH tty-next 0/2] serial: Add driver for National Instruments UARTs

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]


This patch series adds a driver for the 16550-like UARTs on National
Instruments (NI) embedded controller hardware.

These UARTs have an interface that is compatble with the TL16C550C (for
which we build on top of 8250_core) but also has extra registers for
the embedded RS-232/RS-485 tranceiver control circuitry.

  serial: 8250: add driver for NI UARTs
