Subject: [PATCH 3/3] arm64: dts: imx95-15x15-frdm: fix duplicated can-phy node names
Date: Thu, 30 Jul 2026 12:33:28 +0800	[thread overview]
Message-ID: <20260730-can-share-silent-v1-3-63fd603f943d@nxp.com> (raw)
In-Reply-To: <20260730-can-share-silent-v1-0-63fd603f943d@nxp.com>

From: Haibo Chen <haibo.chen@nxp.com>

Both the flexcan2 and flexcan5 CAN transceiver PHY nodes use the same
node name "can-phy", which results in a node name collision. Distinguish
them by using unit-less unique names "can-phy0" and "can-phy1".

These two CAN PHYs share their silent pin, this shared GPIO can be
handled by GPIO shared proxy.
