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).
