Power down panic on Amarda 7040 on linux-aarch64 6.2.10-1

[technosf]

Seeing this on the vanilla linux-aarch64 6.2.10-1 kernel:

[code]
reboot: Power down
ERROR: a8k_system_off: needs to be implemented
lPANIC at PC : 0x0000000004023208
[/code]

I can't tell if this is a compile time misstep or upstream issue. Advice appreciated.
