Same thing happened with Allwinner's SOCs, when the one point of contact that was providing the source of their modified kernel left, Allwinner chipsets stopped getting rapid mainline kernel support. The silver lining though is that the sunxi community has been working to mainline newer chips like the Allwinner H3 & has been doing a bang up job with minimal info, newer kernels can boot up & get most hardware onboard configured & ready to use.
