On Android, drivers are not just in the kernel. The HALs bridge kernel drivers to Android frameworks.
Before discussing drivers, we must understand the target. The MSM8953 is a native ARMv8-A (64-bit) processor. While it can run 32-bit code, its primary instruction set is ARM64 (AArch64). The SoC comprises: msm8953 for arm64 driver high quality
A "driver" in this context is the software layer that allows an operating system—typically Linux-based (Android, postmarketOS, Ubuntu Touch) or a real-time OS (RTOS)—to communicate with these hardware blocks. High-quality drivers mean low latency, no memory leaks, proper power management, and full feature support. On Android, drivers are not just in the kernel

These characteristics shape driver design (AArch64 constraints, aligned memory, exception levels, secure calls).
