The Scorpion CPU is the same between them. The main difference is that the 8060 doesn't have a modem. We probably only need a qcom-***8*60-dragonboard.dts file when the two diverge. That might be soon given that ssbi and the pmic core are in place. Enabling something like the keypad driver should be possible. -- Qualcomm Innovation Center, Inc. is a member of Code Aurora Forum, hosted by The Linux Foundation
