Almost all labels generated by the extracting script are now prefixed with DT_. The only exceptions are: - stuff with 'base_label' specified in yaml bindings - items specified by 'regs_config' and 'name_config' dictionaries in globals.py module - FLASH related labels generated by flash.extract() called separately from generate_node_definitions(), e.g. FLASH_WRITE_BLOCK_SIZE - these are used directly, not through fixups, from existing code so I didn't want to touch them now Labels generated for aliases are additionally prefixed with information from the 'compatible' property, e.g. DT_GPIO_LEDS_LED0_* is generated instead of LED0_*. To provide backward compatibility for code that uses LEDx_* and SWx_* labels in their previous forms, a command line option named 'old-alias-names' is added to the extraction script. This option causes that the labels for aliases are generated in both old and new forms. Currently this option is always enabled in dts.cmake.
