U-Boot drivers/adc/stm32-adc.c depends on these properties , so if you drop them here and U-Boot DTs gets synced with Linux, the ADC driver there will start failing. Can you update the U-Boot ADC driver too ?
Maybe the easiest way would be to retain the old properties for now with a comment, and add the new properties ?
