V1 -> V2:
- No changes in v2.
V2 -> V3:
- Add P3T1035 fallback for P3T2030 as they are functionally identical.
- Add comment in the description explaining the use of P3T2030.

-  The TMP108/P3T1085(NXP) is a digital-output temperature sensor with a
-  dynamically-programmable limit window, and under- and overtemperature
-  alert functions.
+  The TMP108 or NXP P3T Family (P3T1035, P3T1085 and P3T2030) is a digital-
+  output temperature sensor with a dynamically-programmable limit window,
+  and under- and over-temperature alert functions.

-  P3T1085(NXP) support I3C.
+  NXP P3T Family (P3T1035, P3T1085 and P3T2030) supports I3C.

+  P3T2030 is functionally identical to P3T1035. Hence, device tree nodes that
+  use the P3T2030 must provide a fallback compatible string of "nxp,p3t1035"
