title: Google GS101 OTP Controller

maintainers:

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).
