This book will begin with two chapters that will help you understand the basics of drivers and prepare you for the long journey through the Linux kernel. This book will then cover driver development based on Linux subsystems, such as memory management, industrial input/output (IIO), general-purpose input/output (GPIO), interrupt request (IRQ) management, and Inter-Integrated Circuit (I2C) and Serial Peripheral Interface (SPI). The book will also cover a practical approach to direct memory access and register map abstraction.
