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-r8a774c0" for the r8a774C0 TMU 14 - "renesas,tmu-r8a7778" for the r8a7778 TMU 15 - "renesas,tmu-r8a7779" for the r8a7779 TMU 16 - "renesas,tmu-r8a77970" for the r8a77970 TMU 17 - "renesas,tmu-r8a77980" for the r8a77980 TMU 18 - "renesas,tmu" for any TMU. 19 This is a fallback for the above renesas,tmu-* entries 20 21 - reg: base address and length of the registers block for the timer module. 22 23 - interrupts: interrupt-specifier for the timer, one per channel. 24 25 - clocks: a list of phandle + clock-specifier pairs, one for each entry 26 in clock-names. 27 - clock-names: must contain "fck" for the functional clock. 28 29Optional Properties: 30 31 - #renesas,channels: number of channels implemented by the timer, must be 2 32 or 3 (if not specified the value defaults to 3). 33 34 35Example: R8A7779 (R-Car H1) TMU0 node 36 37 tmu0: timer@ffd80000 { 38 compatible = "renesas,tmu-r8a7779", "renesas,tmu"; 39 reg = <0xffd80000 0x30>; 40 interrupts = <0 32 IRQ_TYPE_LEVEL_HIGH>, 41 <0 33 IRQ_TYPE_LEVEL_HIGH>, 42 <0 34 IRQ_TYPE_LEVEL_HIGH>; 43 clocks = <&mstp0_clks R8A7779_CLK_TMU0>; 44 clock-names = "fck"; 45 46 #renesas,channels = <3>; 47 }; 48
