There are 10 gpio instances inside SoC with 3 groups as below: - Group1: main_gpio0, main_gpio2, main_gpio4, main_gpio6 - Group2: main_gpio1, main_gpio3, main_gpio5, main_gpio7 - Group3: wkup_gpio0, wkup_gpio1 Only one instance can be used in each group at a time. So use main_gpio0, main_gpio1 and wkup_gpio0 for the current linux context and mark other gpio nodes as disabled.
