From 3563aaa006af39f4072e114c883f2363cd26b51f Mon Sep 17 00:00:00 2001 From: Peng Fan Date: Fri, 12 Dec 2025 17:57:20 +0800 Subject: [PATCH] arm64: dts: imx8mp-evk: Use phys to replace xceiver-supply The TJA1048 used on i.MX8MP-EVK is actually high-speed CAN transceiver, not a regulator supply. So use phys to reflect the truth.
