Hmm, this dts file is not using the new sun8i-reference-design-tablet.dtsi
file. IIRC your kernel submission was using that ?

Currently u-boot does not have that file yet, but I've a patch
adding it in my sunxi-wip:
https://github.com/jwrdegoede/u-boot-sunxi/commits/sunxi-wip

Please resend this series once the dts file has been accepted
in the kernel and send the exact same file as used in the kernel.

You can use my sunxi-wip branch for now / until the dts-sync
which adds sun8i-reference-design-tablet.dtsi gets merged
in u-boot/master (which should happen soon).

Regards,

Hans
