Description

ADH GT5X Series Optical Fingerprint Sensor

This binding supports fingerprint sensor modules from ADH Technology,
including GT-511C1R, GT-511C3, GT-521F32, and GT-521F52 models.

These sensors use a fixed 12-byte command/response protocol over UART
and support 3-stage enrollment. Model-specific parameters must be
configured via device tree properties to match the hardware variant.
