This series of uart controllers is able to work in IrDA mode.
This adds a flag to the device tree to enable that feature if needed.

How about an array of 1 or 2 entries instead?
I like this idea.
Yes, that would be an alternative. We just weren't sure what type the
elements of the array would have. Could you point to an existing
example?
I think you need device_property_read_u8_array(). I can only find
device_property_read_u32_array() used in the serial drivers tree in
serial_core.c,
but that should be similar.
