The patch subject is inappropriate.  The patch adds a bindings not
device driver.

We usually use specific SoC name in compatible string to specify the
programming model for the hardware.  That said, I do not think we need
"zte,zx2967-thermal".

In the context of tempsensor device, the "tempsensor_" in the clock
names are not really necessary.

"zte,zx296718-thermal"
