Every node in the tree that represents a device is required to have the compatible property. compatible is the key an operating system uses to decide which device driver to bind to a device. compatible is a list of strings. The first string in the list specifies the exact device that the node represents in the form "<manufacturer>,<model>".Jan 23, 2017 · Parsing the device tree means if you are making any entry in the device tree (like in your case " resets = <&lcd_reset>; "); so have to parse the same thing in your driver as well.
