The TDA18218 is not currently supported under Linux.  I have the
information needed to write a driver to support it, but I do not have
any devices that use it, nor any interest (as of now) to write the
driver on my own time.

For me, it would not be very difficult to get this done, as I have
done work to support a similar family of tuners -- TDA18271 /
TDA18211.  The TDA18218 tuner is not supported by the current driver.

In the past, I would have gone ahead and written a driver for the
sheer enjoyment of doing so... but nowadays, I actually have other
projects of a higher priority that need my attention instead.

If, in the future, any commercial entity has interest in seeing this
tuner silicon supported under Linux, they should contact me -- perhaps
my desire to write this driver can be increased ;-)
