Would it be possible to have a single yaml file for all i.MX thermal
sensors by playing with required and optional properties ?

Don't point to thermal.txt anymore. thermal.txt will be replaced by
thermal-*.yaml files at some point soon.

Don't you have multiple sensors connected to this controller? In that
case, 0 won't be a valid value.

i.MX SoCs have many different thermal sensor IP and hence different thermal driver
is used, and different i.MX thermal drivers have different DT bindings, so is it good to
put all of them into single yaml file? For example, imx_thermal.c is for i.MX6/7 SoCs which
do NOT use of_thermal framework, imx8mm_thermal.c is for i.MX8MM/i.MX8MP which
use of_thermal framework.

If putting all of them into 1 yaml file, it will be almost like just putting 2 files together, I
Personally don't think it is a good idea.

OK, will remove it.

imx8mm_thermal driver is for i.MX8MM and i.MX8MP, i.MX8MM ONLY has 1 sensor,
while i.MX8MP has 2 sensors, that is why I put both 0 and 1 here.
