Subject: [PATCH v3 1/2] dt-bindings: can: mcp251xfd: add microchip,xstbyen property
Date: Sat, 21 Mar 2026 19:20:30 +0530 [thread overview]
Message-ID: <20260321135031.3107408-2-viken.dadhaniya@oss.qualcomm.com> (raw)
In-Reply-To: <20260321135031.3107408-1-viken.dadhaniya@oss.qualcomm.com>
Add the boolean property 'microchip,xstbyen' to enable the dedicated
transceiver standby control function on the INT0/GPIO0/XSTBY pin of
the MCP251xFD family.
