Analysis and Implementation of a Linux Kernel Fingerprint Driver: A Case Study of the CS9711 Sensor

Cause: Driver conflict or power management issue. Fix: cs9711 fingerprint driver

CS9711 is a capacitive fingerprint sensor IC commonly used in embedded and mobile devices. A driver for CS9711 interfaces the sensor with an OS (typically Linux/Android) over SPI/I²C and GPIO, handling power management, image capture, preprocessing, and communication with higher-level fingerprint frameworks (e.g., Android Fingerprint HAL or Linux/Userspace daemon).
