1* Renesas R-Mobile/R-Car Timer Unit (TMU) 2 3The TMU is a 32-bit timer/counter with configurable clock inputs and 4programmable compare match. 5 6Channels share hardware resources but their counter and compare match value 7are independent. The TMU hardware supports up to three channels. 8 9Required Properties: 10 11 - compatible: must contain one or more of the following: 12 - "renesas,tmu-r8a7740" for the r8a7740 TMU 13 - "renesas,tmu-r8a774a1" for the r8a774A1 TMU 14 - "renesas,tmu-r8a774b1" for the r8a774B1 TMU 15 - "renesas,tmu-r8a774c0" for the r8a774C0 TMU 16 - "renesas,tmu-r8a7778" for the r8a7778 TMU 17 - "renesas,tmu-r8a7779" for the r8a7779 TMU 18 - "renesas,tmu-r8a77970" for the r8a77970 TMU 19 - "renesas,tmu-r8a77980" for the r8a77980 TMU 20 - "renesas,tmu" for any TMU. 21 This is a fallback for the above renesas,tmu-* entries 22 23 - reg: base address and length of the registers block for the timer module. 24 25 - interrupts: interrupt-specifier for the timer, one per channel. 26 27 - clocks: a list of phandle + clock-specifier pairs, one for each entry 28 in clock-names. 29 - clock-names: must contain "fck" for the functional clock. 30 31Optional Properties: 32 33 - #renesas,channels: number of channels implemented by the timer, must be 2 34 or 3 (if not specified the value defaults to 3). 35 36 37Example: R8A7779 (R-Car H1) TMU0 node 38 39 tmu0: timer@ffd80000 { 40 compatible = "renesas,tmu-r8a7779", "renesas,tmu"; 41 reg = <0xffd80000 0x30>; 42 interrupts = <0 32 IRQ_TYPE_LEVEL_HIGH>, 43 <0 33 IRQ_TYPE_LEVEL_HIGH>, 44 <0 34 IRQ_TYPE_LEVEL_HIGH>; 45 clocks = <&mstp0_clks R8A7779_CLK_TMU0>; 46 clock-names = "fck"; 47 48 #renesas,channels = <3>; 49 }; 50
