    description: |
      Value to use for DDR-Backup Power (default 0).
      This is a bitmask that specifies which DDR power rails need to be kept
      powered when backup mode is entered, for system suspend:
        - bit 0: DDR0
        - bit 1: DDR1
        - bit 2: DDR0C
        - bit 3: DDR1C
      These bits match the KEEPON_DDR* bits in the documentation for the "BKUP
      Mode Cnt" register.

      The RSTB signal is configured for level mode, to accommodate a toggle
      power switch (the RSTBMODE pin is strapped low).
