[PATCH 0/3] arm64: dts: freescale: Use phys to replace xceiver-supply

[PATCH 0/3] arm64: dts: freescale: Use phys to replace xceiver-supply

[Peng Fan (OSS)]

This is a pick up of patch 6-8 from [1].

The drivers changes have been picked in 6.18, just resend the dts changes.

[1]https://lore.kernel.org/linux-phy/20251001-can-v7-0-fad29efc3884@nxp.com/

There are still some other device trees not converted to use phys,
those will be converted later.

[PATCH 1/3] arm64: dts: imx95-15x15-evk: Use phys to replace xceiver-supply

[Peng Fan (OSS)]

From: Peng Fan <peng.fan@nxp.com>

The TJA1051T/3 used on i.MX95-15x15-EVK is actually high-speed CAN
transceiver, not a regulator supply. So use phys to reflect the truth.
