Writing a Linux kernel device driver involves an 8-stage workflow: device type identification, subsystem architecture review, skeleton implementation, device tree bindings, probe/remove functions, and power management. This ensures compilable, idiomatic C code for kernel module development.

Implementing probe and remove functions for a platform driver requires using `devm_*` resource management for automatic cleanup. Proper probe/remove implementation handles device tree bindings, manages IRQs, and registers with subsystems like IIO to ensure robust kernel module behavior.

Adding device tree bindings for an I2C sensor driver involves defining hardware properties in the device tree and parsing them during the probe function. This process integrates with the IIO subsystem to correctly initialize and register the custom sensor.

Yes, the driver development workflow explicitly supports power management integration. It guides you through incorporating power management into the kernel module, ensuring the device driver handles power states correctly alongside robust error handling and `devm_*` resource cleanup.

Yes, you can use this approach to build a character device driver for a memory-mapped peripheral. The workflow generates compilable C code and explanations tailored to character devices, platform drivers, and I2C/SPI drivers for embedded systems.
