Mon Feb 20 22:55:02 PST 2017
From: Orson Zhai <orson.zhai at spreadtrum.com>
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.
