> The driver requires that CAN_STB signal be driven low to enable
> CAN PHY. Currently this is being managed from U-boot. Will submit a patch

The formatting above should use tabs instead of spaces. Please
check and run checkpatch.pl --strict on this.
Also, sounds like the Kconfig changes should be 2/2, not 1/2
to enable this.
