This bit looks good, but please submit dts file patches to the upstream
linux kernel first, using the standard kernel patch submission process.

Also as said before if your I7 version has an eMMC, please add
a new dts file for this titled: arch/arm/dts/sun6i-a31-mele-i7-emmc.dts .

Please submit this new file upstream.

This change is completely unrelated to the emmc changes, please
submit this as a separate patch. Please also explain why you are
making this change, where does the 251 value come from ?
