[PATCH v4 21/21] arm64: dts: allwinner: Add OrangePi Zero 2 .dts

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The OrangePi Zero 2 is a development board with the new H616 SoC.

It features the usual connectors used on those small boards, and comes
with the AXP305, which seems to be compatible with the AXP805.

For more details see: http://linux-sunxi.org/Xunlong_Orange_Pi_Zero2
