Channels share hardware resources but their counter and compare match value are independent. The TMU hardware supports up to three channels. properties: compatible: items: - enum: - renesas,tmu-r8a73a4 # R-Mobile APE6 - renesas,tmu-r8a7740 # R-Mobile A1 - renesas,tmu-r8a7742 # RZ/G1H - renesas,tmu-r8a7743 # RZ/G1M - renesas,tmu-r8a7744 # RZ/G1N - renesas,tmu-r8a7745 # RZ/G1E - renesas,tmu-r8a77470 # RZ/G1C - renesas,tmu-r8a774a1 # RZ/G2M - renesas,tmu-r8a774b1 # RZ/G2N - renesas,tmu-r8a774c0 # RZ/G2E - renesas,tmu-r8a774e1 # RZ/G2H - renesas,tmu-r8a7778 # R-Car M1A - renesas,tmu-r8a7779 # R-Car H1 - renesas,tmu-r8a7790 # R-Car H2 - renesas,tmu-r8a7791 # R-Car M2-W - renesas,tmu-r8a7792 # R-Car V2H - renesas,tmu-r8a7793 # R-Car M2-N - renesas,tmu-r8a7794 # R-Car E2 - renesas,tmu-r8a7795 # R-Car H3 - renesas,tmu-r8a7796 # R-Car M3-W - renesas,tmu-r8a77961 # R-Car M3-W+ - renesas,tmu-r8a77965 # R-Car M3-N - renesas,tmu-r8a77970 # R-Car V3M - renesas,tmu-r8a77980 # R-Car V3H - renesas,tmu-r8a77990 # R-Car E3 - renesas,tmu-r8a77995 # R-Car D3 - renesas,tmu-r8a779a0 # R-Car V3U - renesas,tmu-r8a779f0 # R-Car S4-8 - renesas,tmu-r8a779g0 # R-Car V4H - renesas,tmu-r8a779h0 # R-Car V4M - const: renesas,tmu reg: maxItems: 1 interrupts: minItems: 2 items: - description: Underflow interrupt, channel 0 - description: Underflow interrupt, channel 1 - description: Underflow interrupt, channel 2 - description: Input capture interrupt, channel 2 interrupt-names: minItems: 2 items: - const: tuni0 - const: tuni1 - const: tuni2 - const: ticpi2 clocks: maxItems: 1 clock-names: const: fck power-domains: maxItems: 1 resets: maxItems: 1 '#renesas,channels': description: Number of channels implemented by the timer. $ref: /schemas/types.yaml#/definitions/uint32 enum: [ 2, 3 ] default: 3 required: - compatible - reg - interrupts - interrupt-names - clocks - clock-names - power-domains if: not: properties: compatible: contains: enum: - renesas,tmu-r8a73a4 - renesas,tmu-r8a7740 - renesas,tmu-r8a7778 - renesas,tmu-r8a7779 then: required: - resets additionalProperties: false examples: - | #include #include #include tmu0: timer@ffd80000 { compatible = "renesas,tmu-r8a7779", "renesas,tmu"; reg = <0xffd80000 0x30>; interrupts = , , , ; interrupt-names = "tuni0", "tuni1", "tuni2", "ticpi2"; clocks = <&mstp0_clks R8A7779_CLK_TMU0>; clock-names = "fck"; power-domains = <&sysc R8A7779_PD_ALWAYS_ON>; #renesas,channels = <3>; };
