Not entirely. They use (or at least have used) mediatek chipsets. Their drivers... well, do a github search for mediatek chipset-based android source code. People have placed entire dumps of Mediatek stuff on Github... and the stuff I could find in 5min is SCARY. Fucking scary. And that's just the tools for the manufacturer, their kernel drivers are a mess of ifdefs and commented out code, with the sparse comments written in some Asian language.
