The R-Car and RZ/G Reset Controllers provide reset control, and implement the

||
|
|
- Mode monitoring register,
|
||
|
|
- Reset control of peripheral devices (on R-Car Gen1),
|
||
|
|
- Watchdog timer (on R-Car Gen1),
|
||
|
|
- Register-based reset control and boot address registers for the various CPU
|
||
|
|
cores (on R-Car Gen2 and Gen3, and on RZ/G).
|
||
|
|
|
||
|
|
|
||
|
|
Required properties:
|
||
|
|
- compatible: Should be
|
||
|
|
- "renesas,<soctype>-reset-wdt" for R-Car Gen1,
|
||
|
|
- "renesas,<soctype>-rst" for R-Car Gen2 and Gen3, and RZ/G
|
||
|
|
Examples with soctypes are:
|
||
|
|
- "renesas,r8a7743-rst" (RZ/G1M)
|
||
|
|
- "renesas,r8a7745-rst" (RZ/G1E)

||
|
|
- "renesas,r8a7778-reset-wdt" (R-Car M1A)
|
||
|
|
- "renesas,r8a7779-reset-wdt" (R-Car H1)
|
||
|
|
- "renesas,r8a7790-rst" (R-Car H2)

|
||
|

|
||
|
|
rst: reset-controller@e6160000 {
|
||
|
