1DT bindings for the Renesas R-Car and RZ/G Reset Controllers 2 3The R-Car and RZ/G Reset Controllers provide reset control, and implement the 4following 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). 11 12 13Required properties: 14 - compatible: Should be 15 - "renesas,<soctype>-reset-wdt" for R-Car Gen1, 16 - "renesas,<soctype>-rst" for R-Car Gen2 and Gen3, and RZ/G 17 Examples with soctypes are: 18 - "renesas,r8a7743-rst" (RZ/G1M) 19 - "renesas,r8a7744-rst" (RZ/G1N) 20 - "renesas,r8a7745-rst" (RZ/G1E) 21 - "renesas,r8a77470-rst" (RZ/G1C) 22 - "renesas,r8a774a1-rst" (RZ/G2M) 23 - "renesas,r8a774c0-rst" (RZ/G2E) 24 - "renesas,r8a7778-reset-wdt" (R-Car M1A) 25 - "renesas,r8a7779-reset-wdt" (R-Car H1) 26 - "renesas,r8a7790-rst" (R-Car H2) 27 - "renesas,r8a7791-rst" (R-Car M2-W) 28 - "renesas,r8a7792-rst" (R-Car V2H 29 - "renesas,r8a7793-rst" (R-Car M2-N) 30 - "renesas,r8a7794-rst" (R-Car E2) 31 - "renesas,r8a7795-rst" (R-Car H3) 32 - "renesas,r8a7796-rst" (R-Car M3-W) 33 - "renesas,r8a77965-rst" (R-Car M3-N) 34 - "renesas,r8a77970-rst" (R-Car V3M) 35 - "renesas,r8a77980-rst" (R-Car V3H) 36 - "renesas,r8a77990-rst" (R-Car E3) 37 - "renesas,r8a77995-rst" (R-Car D3) 38 - reg: Address start and address range for the device. 39 40 41Example: 42 43 rst: reset-controller@e6160000 { 44 compatible = "renesas,r8a7795-rst"; 45 reg = <0 0xe6160000 0 0x0200>; 46 }; 47
