| DT bindings for the Renesas R-Car and RZ/G Reset Controllers |
| |
| The R-Car and RZ/G Reset Controllers provide reset control, and implement the |
| following functions: |
| - Latching of the levels on mode pins when PRESET# is negated, |
| - 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) |
| - "renesas,r8a7791-rst" (R-Car M2-W) |
| - "renesas,r8a7792-rst" (R-Car V2H |
| - "renesas,r8a7793-rst" (R-Car M2-N) |
| - "renesas,r8a7794-rst" (R-Car E2) |
| - "renesas,r8a7795-rst" (R-Car H3) |
| - "renesas,r8a7796-rst" (R-Car M3-W) |
| - reg: Address start and address range for the device. |
| |
| |
| Example: |
| |
| rst: reset-controller@e6160000 { |
| compatible = "renesas,r8a7795-rst"; |
| reg = <0 0xe6160000 0 0x0200>; |
| }; |
