[PATCH 0/2] Add support for TI TCAN1046 CAN transceiver

[Prabhakar]

From: Lad Prabhakar <prabhakar.mahadev-lad.rj@bp.renesas.com>

Hi All,

This patch series adds support for the TI TCAN1046 automotive CAN
transceiver. The TCAN1046 provides dual high-speed CAN channels and
includes STB1/2 control lines.

Cheers,
Prabhakar

[PATCH 2/2] phy: phy-can-transceiver: Add support for TI TCAN1046

From: Lad Prabhakar <prabhakar.mahadev-lad.rj@bp.renesas.com>

Add support for the TI TCAN1046 automotive CAN transceiver. The TCAN1046
provides dual CAN channels and exposes STB1/2 control pins similar to the
NXP TJA1048. Reuse the existing `tja1048_drvdata` configuration for
TCAN1046.

according to patch2, which is the compatible as nxp,tja1048. why not allow
ti,tcan1046 fallback to nxp,tja1048.

So needn't change driver code.

Agreed, I'll do this change and send a v2.
