m_can can be a wakeup source on some devices. Especially on some of the am62* SoCs pins, connected to m_can in the mcu, can be used to wakeup the SoC. The wakeup-source property defines on which devices m_can can be used for wakeup and in which power states. The pins associated with m_can have to have a special configuration to be able to wakeup the SoC. This configuration is described in the wakeup pinctrl state while the default state describes the default configuration.
