[PATCH 2/7] dt-bindings: can: m_can: Add wakeup pinctrl state

[Markus Schneider-Pargmann]

Pins associated with m_can can be the source of a wakeup in deep sleep
states. To be able to wakeup these pins have to be configured in a
special way. To support this configuration add the default and wakeup
pinctrl states.
