Log: Add support for NXP/Freescale etsec2 ethernet controller Adding the compatible property check isn't enough. Device trees for eTSEC2 devices are missing a 'reg' property on the eTSEC node itself, relegating it to the queue group child nodes. Still left to do: add Multigroup mode support (see QorIQ reference manuals s for SoCs with eTSEC2).
