I had an additional look for the possible problem with the AXP813 for BananaPi M3 in U-Boot. With help of Google, i found a patchset for U-Boot from 2016:

In the Debian configuration, i found the following:

I presume this is configs/Sinovoip_BPI_M3_defconfig ?

Some CONFIG_AXP_... are missing in the Debian configuration. Is it possible, that these missing AXP-configs have to be added in the Debian configuration?

If i can do some tests, please let me know.

Debian doesn't have any patches that should affect this; CCing upstream. Hopefully someone there has some suggestions or ideas.
