The TI uart hardware is ns16550-compatible, except that before it can be used the clocks and power have to be enabled and a non-standard mode control register has to be set to put the device in uart mode (as opposed to irDa or other serial protocols). This adds the extra code in an extension to the standard ns8250 probe routine, and the rest of the driver is just the standard ns8250 code.
