I like this idea. OMAP UART (8250_omap) also can be switched to IrDA
mode, but I don't know anyone who use it.

This patch set adds IrDA support to the 8250_dw driver. The first patch exposes
the set_ldisc() function in the 8250 driver so it can be overridden, and the
second patch adds a set_ldisc() function to the 8250_dw driver which enables /
disables IrDA SIR mode if supported.

v2:
  The 8250_dw set_ldisc() function no longer tries to enable/disable IrDA SIR
  mode if not supported by the hardware configuration.

Ed Blake (2):
  serial: 8250: Expose set_ldisc function
  serial: 8250_dw: Add support for IrDA SIR mode
