+
+description: |
+  OTP controller drives a NVMEM memory where system or user specific data
+  can be stored. The OTP controller register space is of interest as well
+  because it contains dedicated registers where it stores the Product ID
+  and the Chip ID (apart other things like TMU or ASV info).
