Drivers

Device drivers instantiated from the compile-time device description. More...

Collaboration diagram for Drivers:

Modules
	Block devices
	Storage read and written in fixed-size sectors, such as a ramdisk.
	Console
	Direct access, outside the VFS, to the device named by chosen.console.
	GPIO
	Pin configuration, output, and input on GPIO ports.
	LEDs
	Numbered LEDs, their /dev/ledN files, and the driver interface.

Detailed Description

Device drivers instantiated from the compile-time device description.

soc.yaml and board.yaml describe the hardware; the generator creates each enabled device's configuration and calls its driver from dt_init(), after the devices it references. Driver headers are internal to src/drivers/; the public parts are the interfaces other code uses: the console, GPIO ports, LEDs, and block devices.

Drivers explains the model and links a page per driver class: Serial ports, GPIO ports, LEDs, and Block devices. Device bindings lists every compatible. See the Development guide's "Device description" section.
