From: Faiz Abbas <faiz_abbas at ti.com>
There are 6 gpio instances inside SoC with 2 groups as show below:
Group one: wkup_gpio0, wkup_gpio1
Group two: main_gpio0, main_gpio2, main_gpio4, main_gpio6
Only one instance from each group can be used at a time. So use main_gpio0
and wkup_gpio0 in current linux context and disable the rest of the nodes.
