The kernel API provides its own HAL; what these drivers do is provide a "HAL to HAL" translation layer from their own internal HAL to the kernel HAL, often adding variants on existing kernel infrastructure (your own spinlock implementation, for example), because the existing infrastructure has different semantics to your internal version, and you don't want to translate between them.
