7 title: Renesas RZ/N1 Analog to Digital Converter (ADC)
10 - Herve Codina <herve.codina@bootlin.com>
13 The Renesas RZ/N1 ADC controller available in the Renesas RZ/N1 SoCs family
14 can use up to two internal ADC cores (ADC1 and ADC2) those internal cores are
15 handled through ADC controller virtual channels.
