To compile it as a module, choose M here: the module will be called

help
Say Y or M here if you want to build support for the PXA2xx
built-in IRDA interface which can support both SIR and FIR.
This driver relies on platform specific helper routines so
available capabilities may vary from one PXA2xx target to
another.
