[PATCH V5 1/4] arm64: dts: Add basic DT to support Spreadtrum's SP9860G

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

 




From: Orson Zhai <orson.zhai@xxxxxxxxxxxxxx>

SC9860G is a 8 cores of A53 SoC with 4G LTE support SoC from Spreadtrum.

According to regular hierarchy of sprd dts, whale2.dtsi contains SoC
peripherals IP nodes, sc9860.dtsi contains stuff related to ARM core stuff
and sp9860g dts is for the board level.
