[PATCH v3 1/6] dt-bindings: phy: ti,tcan104x-can: Document NXP TJA105X/1048
Posted by Peng Fan 1 month ago
The TJA105[1,7] is a high-speed CAN transceiver which is a pin-compatible
alternative for TI TCAN1043 with sleep mode supported, and has a compatible
programming model, therefore use ti,tcan1043 as fallback compatible.

The TJA1048 is a dual high-speed CAN transceiver with sleep mode supported.
