   1 DT bindings for the Renesas R-Car and RZ/G Reset Controllers
   2
   3 The R-Car and RZ/G Reset Controllers provide reset control, and implement the
   4 following functions:
   5   - Latching of the levels on mode pins when PRESET# is negated,
   6   - Mode monitoring register,
   7   - Reset control of peripheral devices (on R-Car Gen1),
   8   - Watchdog timer (on R-Car Gen1),
   9   - Register-based reset control and boot address registers for the various CPU
  10     cores (on R-Car Gen2 and Gen3, and on RZ/G).
