The TDA18211HN is fully supported by the tda18271 module. The driver
will not need anything specific to tune into new broadcast standards
-- just the filters need to be set up properly.
All of the differences in setup are exposed by the driver in the
attach-time configuration structure, so the driver would not need any
modification to work properly with new demodulator hardware, other
than some tweaking in the attach-time configuration structure
overrides. (without the overrides, the driver will use default
behavior, which is appropriate for some but not all designs).
I do not know of anybody working on a driver for the tda10055.
