| * Renesas R-Car Compare Match Timer (CMT) | |
| The CMT is a multi-channel 16/32/48-bit timer/counter with configurable clock | |
| inputs and programmable compare match. | |
| Channels share hardware resources but their counter and compare match value | |
| 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. | |
| Required Properties: | |
| - compatible: must contain one or more of the following: | |
| - "renesas,cmt-48-sh73a0" for the sh73A0 48-bit CMT | |
| (CMT1) | |
| - "renesas,cmt-48-r8a7740" for the r8a7740 48-bit CMT | |
| (CMT1) | |
| - "renesas,cmt-48" for all non-second generation 48-bit CMT | |
| (CMT1 on sh73a0 and r8a7740) | |
| This is a fallback for the above renesas,cmt-48-* entries. | |
| - "renesas,cmt0-r8a73a4" for the 32-bit CMT0 device included in r8a73a4. | |
| - "renesas,cmt1-r8a73a4" for the 48-bit CMT1 device included in r8a73a4. | |
| - "renesas,cmt0-r8a7790" for the 32-bit CMT0 device included in r8a7790. | |
| - "renesas,cmt1-r8a7790" for the 48-bit CMT1 device included in r8a7790. | |
| - "renesas,cmt0-r8a7791" for the 32-bit CMT0 device included in r8a7791. | |
| - "renesas,cmt1-r8a7791" for the 48-bit CMT1 device included in r8a7791. | |
| - "renesas,cmt0-r8a7793" for the 32-bit CMT0 device included in r8a7793. | |
| - "renesas,cmt1-r8a7793" for the 48-bit CMT1 device included in r8a7793. | |
| - "renesas,cmt0-r8a7794" for the 32-bit CMT0 device included in r8a7794. | |
| - "renesas,cmt1-r8a7794" for the 48-bit CMT1 device included in r8a7794. | |
| - "renesas,rcar-gen2-cmt0" for 32-bit CMT0 devices included in R-Car Gen2. | |
| - "renesas,rcar-gen2-cmt1" for 48-bit CMT1 devices included in R-Car Gen2. | |
| These are fallbacks for r8a73a4 and all the R-Car Gen2 | |
| entries listed above. | |
| - reg: base address and length of the registers block for the timer module. | |
| - interrupts: interrupt-specifier for the timer, one per channel. | |
| - clocks: a list of phandle + clock-specifier pairs, one for each entry | |
| in clock-names. | |
| - clock-names: must contain "fck" for the functional clock. | |
