Yeah, so do you think below change works for you?

ARM64: dts: hisilicon: add missed thermal sensors for Hi6220

The thermal driver tries to register four sensors but the DT only binds
one sensor (sensor ID 2) with thermal zone, as result the thermal driver
reports failure for missed thermal sensor binding.

This patch adds missed thermal sensor for Hi6220, so can dismiss the
booting failure log.

I personally prefer to avoid doing this, if only register one unique
sensor this will let us have no flexiblity for trying multiple sensors
on this platform.

Thanks,
