It's not clear what the possible values for the 2ghz property are,
can you be more verbose in the description? How is <0> different
from no property?

0 means disabled, no property means unchanged (compared to EEPROM).

Maybe have a boolean property instead then to say "mediatek,2ghz-disabled" ?

If zero is the only possible value, there is no need to put a number in there.

1 is also possible, which will force-enable the capability.

Ok, then both those values should be documented in the binding.

Related to this, Martin sent patches which add generic bindings for
enabling 2 Ghz and 5 Ghz bands.
