Subject: [PATCH 1/6] dt-bindings: phy: ti,tcan104x-can: Document NXP TJA1051/1048
Date: Fri, 22 Aug 2025 12:05:28 +0800 [thread overview]
Message-ID: <20250822-can-v1-1-c075f702adea@nxp.com> (raw)
In-Reply-To: <20250822-can-v1-0-c075f702adea@nxp.com>
The TJA1051 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.
