| Timer / Counter channel to use, channel 0 is the default. |
| Valid range: 0 - 2 |

| description: | |
| If set to true the `clk` property is ignored. Instead the TC module is |
| driven directly via MCLK. Only supported on sam4e, same70, same70b, |
| samv71, samv71b SoC series. |

| description: | |
| Alternate value of the CMR (Channel Mode Register) register. |
| If specified this value will be written to the register during driver |
| instance initialization instead of the default. It can be used to |
| configure the timer / counter in the custom mode. Together with other |
| properties like channel-num, pinctrl-0 this allows e.g. to configure |
| the driver to count events generated on the TIOA, TIOB signal connected |
| to the external pin. |

| reg-rc: |
| type: int |
| required: false |
| description: | |
| Register C compare/match value. RC can be used as compare/match unit |
| for an specific timer unit. Their use depends on how timer channel |
| is configured,see reg-cmr. It can be used as trigger for both input |
| capture or counter mode, or even as event source. The RC register |
| behavior is SoC dependent. For more information and use cases, |
| check SoC datasheet and application notes. |
