The existence of a vibrant upstream project provides a solid base for high-quality driver development.
The (Snapdragon 625) is a widely used ARM64 system-on-chip (SoC) primarily found in Android smartphones, tablets, and automotive head units. Developing or finding a "high-quality" driver for this chipset typically involves working with the Mainline Linux Kernel or specific Qualcomm Android BSPs (Board Support Packages). msm8953 for arm64 driver high quality
