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.
