[PATCH v2 1/2] dt-bindings: phy: ti,tcan104x-can: Document mux-states property

From: Aswath Govindraju
Date: Tue Dec 14 2021 - 09:30:08 EST


On some boards, for routing CAN signals from controller to transceivers,
muxes might need to be set. This can be implemented using mux-states
property. Therefore, document the same in the respective bindings.
