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

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.
