It would be perfect if this it true.  But I tried with the following
change, it just makes QORIQ_CPUFREQ non-selectable if THERMAL=m.

Oops.

I find we can achieve your desired result with the following change instead:

+       depends on (THERMAL=m && m) || THERMAL=y || THERMAL=n

"depends on THERMAL || !THERMAL" should also work.

Right.  And this is more simpler.

Note the check on !CPU_THERMAL rather than !THERMAL in my patch, that
part was correct. I think the line should be

	depends on !CPU_THERMAL || THERMAL

as some other drivers do. I must have copied the line
from ARM_MT8173_CPUFREQ, which is a 'bool' symbol, when
it should have been the same as ARM_BIG_LITTLE_CPUFREQ and
CPUFREQ_DT.
