Channels share hardware resources but their counter and compare match values are independent. A particular CMT instance can implement only a subset of the channels supported by the CMT model. Channel indices represent the hardware position of the channel in the CMT and don't match the channel numbers in the datasheets. properties: compatible: oneOf: - items: - enum: - renesas,r8a7740-cmt0 # 32-bit CMT0 on R-Mobile A1 - renesas,r8a7740-cmt1 # 48-bit CMT1 on R-Mobile A1 - renesas,r8a7740-cmt2 # 32-bit CMT2 on R-Mobile A1 - renesas,r8a7740-cmt3 # 32-bit CMT3 on R-Mobile A1 - renesas,r8a7740-cmt4 # 32-bit CMT4 on R-Mobile A1 - renesas,sh73a0-cmt0 # 32-bit CMT0 on SH-Mobile AG5 - renesas,sh73a0-cmt1 # 48-bit CMT1 on SH-Mobile AG5 - renesas,sh73a0-cmt2 # 32-bit CMT2 on SH-Mobile AG5 - renesas,sh73a0-cmt3 # 32-bit CMT3 on SH-Mobile AG5 - renesas,sh73a0-cmt4 # 32-bit CMT4 on SH-Mobile AG5 - items: - enum: - renesas,r8a73a4-cmt0 # 32-bit CMT0 on R-Mobile APE6 - renesas,r8a7742-cmt0 # 32-bit CMT0 on RZ/G1H - renesas,r8a7743-cmt0 # 32-bit CMT0 on RZ/G1M - renesas,r8a7744-cmt0 # 32-bit CMT0 on RZ/G1N - renesas,r8a7745-cmt0 # 32-bit CMT0 on RZ/G1E - renesas,r8a77470-cmt0 # 32-bit CMT0 on RZ/G1C - renesas,r8a7790-cmt0 # 32-bit CMT0 on R-Car H2 - renesas,r8a7791-cmt0 # 32-bit CMT0 on R-Car M2-W - renesas,r8a7792-cmt0 # 32-bit CMT0 on R-Car V2H - renesas,r8a7793-cmt0 # 32-bit CMT0 on R-Car M2-N - renesas,r8a7794-cmt0 # 32-bit CMT0 on R-Car E2 - const: renesas,rcar-gen2-cmt0 # 32-bit CMT0 on R-Mobile APE6, R-Car Gen2 and RZ/G1 - items: - enum: - renesas,r8a73a4-cmt1 # 48-bit CMT1 on R-Mobile APE6 - renesas,r8a7742-cmt1 # 48-bit CMT1 on RZ/G1H - renesas,r8a7743-cmt1 # 48-bit CMT1 on RZ/G1M - renesas,r8a7744-cmt1 # 48-bit CMT1 on RZ/G1N - renesas,r8a7745-cmt1 # 48-bit CMT1 on RZ/G1E - renesas,r8a77470-cmt1 # 48-bit CMT1 on RZ/G1C - renesas,r8a7790-cmt1 # 48-bit CMT1 on R-Car H2 - renesas,r8a7791-cmt1 # 48-bit CMT1 on R-Car M2-W - renesas,r8a7792-cmt1 # 48-bit CMT1 on R-Car V2H - renesas,r8a7793-cmt1 # 48-bit CMT1 on R-Car M2-N - renesas,r8a7794-cmt1 # 48-bit CMT1 on R-Car E2 - const: renesas,rcar-gen2-cmt1 # 48-bit CMT1 on R-Mobile APE6, R-Car Gen2 and RZ/G1 - items: - enum: - renesas,r8a774a1-cmt0 # 32-bit CMT0 on RZ/G2M - renesas,r8a774b1-cmt0 # 32-bit CMT0 on RZ/G2N - renesas,r8a774c0-cmt0 # 32-bit CMT0 on RZ/G2E - renesas,r8a774e1-cmt0 # 32-bit CMT0 on RZ/G2H - renesas,r8a7795-cmt0 # 32-bit CMT0 on R-Car H3 - renesas,r8a7796-cmt0 # 32-bit CMT0 on R-Car M3-W - renesas,r8a77961-cmt0 # 32-bit CMT0 on R-Car M3-W+ - renesas,r8a77965-cmt0 # 32-bit CMT0 on R-Car M3-N - renesas,r8a77970-cmt0 # 32-bit CMT0 on R-Car V3M - renesas,r8a77980-cmt0 # 32-bit CMT0 on R-Car V3H - renesas,r8a77990-cmt0 # 32-bit CMT0 on R-Car E3 - renesas,r8a77995-cmt0 # 32-bit CMT0 on R-Car D3 - const: renesas,rcar-gen3-cmt0 # 32-bit CMT0 on R-Car Gen3 and RZ/G2 - items: - enum: - renesas,r8a774a1-cmt1 # 48-bit CMT on RZ/G2M - renesas,r8a774b1-cmt1 # 48-bit CMT on RZ/G2N - renesas,r8a774c0-cmt1 # 48-bit CMT on RZ/G2E - renesas,r8a774e1-cmt1 # 48-bit CMT on RZ/G2H - renesas,r8a7795-cmt1 # 48-bit CMT on R-Car H3 - renesas,r8a7796-cmt1 # 48-bit CMT on R-Car M3-W - renesas,r8a77961-cmt1 # 48-bit CMT on R-Car M3-W+ - renesas,r8a77965-cmt1 # 48-bit CMT on R-Car M3-N - renesas,r8a77970-cmt1 # 48-bit CMT on R-Car V3M - renesas,r8a77980-cmt1 # 48-bit CMT on R-Car V3H - renesas,r8a77990-cmt1 # 48-bit CMT on R-Car E3 - renesas,r8a77995-cmt1 # 48-bit CMT on R-Car D3 - const: renesas,rcar-gen3-cmt1 # 48-bit CMT on R-Car Gen3 and RZ/G2 - items: - enum: - renesas,r8a779a0-cmt0 # 32-bit CMT0 on R-Car V3U - renesas,r8a779f0-cmt0 # 32-bit CMT0 on R-Car S4-8 - renesas,r8a779g0-cmt0 # 32-bit CMT0 on R-Car V4H - renesas,r8a779h0-cmt0 # 32-bit CMT0 on R-Car V4M - const: renesas,rcar-gen4-cmt0 # 32-bit CMT0 on R-Car Gen4 - items: - enum: - renesas,r8a779a0-cmt1 # 48-bit CMT on R-Car V3U - renesas,r8a779f0-cmt1 # 48-bit CMT on R-Car S4-8 - renesas,r8a779g0-cmt1 # 48-bit CMT on R-Car V4H - renesas,r8a779h0-cmt1 # 48-bit CMT on R-Car V4M - const: renesas,rcar-gen4-cmt1 # 48-bit CMT on R-Car Gen4 reg: maxItems: 1 interrupts: minItems: 1 maxItems: 8 clocks: maxItems: 1 clock-names: const: fck power-domains: maxItems: 1 resets: maxItems: 1 required: - compatible - reg - interrupts - clocks - clock-names - power-domains allOf: - if: properties: compatible: contains: enum: - renesas,rcar-gen2-cmt0 - renesas,rcar-gen3-cmt0 - renesas,rcar-gen4-cmt0 then: properties: interrupts: minItems: 2 maxItems: 2 - if: properties: compatible: contains: enum: - renesas,rcar-gen2-cmt1 - renesas,rcar-gen3-cmt1 - renesas,rcar-gen4-cmt1 then: properties: interrupts: minItems: 8 maxItems: 8 additionalProperties: false examples: - | #include <dt-bindings/clock/r8a7790-cpg-mssr.h> #include <dt-bindings/interrupt-controller/arm-gic.h> #include <dt-bindings/power/r8a7790-sysc.h> cmt0: timer@ffca0000 { compatible = "renesas,r8a7790-cmt0", "renesas,rcar-gen2-cmt0";
