The Mapleboard MP130 is a single board computer based on the Allwinner
H3 SoC, with all schematics freely available. The Lite version includes
1GB main memory and 8GB eMMC.

https://www.mapleboard.org/en (still mostly in Chinese even when English
is selected)

This DTS is based upon the DTS shipped with the board which uses
mapleboard,mp130- prefixes instead of the allwinner,sun8i variants.

That was my mistake, but it was correct in your first version.

You don't need these nodes at all.

I've fixed both issues and applied your patch for 4.21

Thanks!
