Thank you for pointing out that those gpio-line-names are really
specific to the BeagleBone Black and not applicable for other boards
like the BeagleBone Green which lack eMMC.

I will post a new patch for am335x-boneblack.dts.

After that is reviewed and applied, I will then create patches for the
the other BeagleBone models.

thanks,
