Gen 1-2 are SoC SC8180X and SC8180XP respectively which are the same SoC except for the CPU frequency https://git.linaro.org/landing-teams/working/qualcomm/kernel.git/log/?qt=grep&q=SC8180. Gen 3 is SoC SC8280 https://git.linaro.org/landing-teams/working/qualcomm/kernel.git/log/?qt=grep&q=SC8280 Best Regards, Alfredo
