So this is question for authors of that commit 84e0f1c13806. But it looks like I cannot send them emails because of following error: : connect to freescale.com[192.88.156.33]:25: Connection timed out Do you have other way how to contact maintainers of that DTS file? arch/powerpc/boot/dts/fsl/t1023rdb.dts > PHY mode sgmii-2500 does not exist in mainline. Yes, this is reason why I sent this email. In DTS is specified this mode which does not exist. > Andrew >
