Custom board using Octavo OSD3358-base. I am connecting analog inputs AIN0, AIN1, AIN2, AIN3 and VREFN (VREFN_ADC). I understand I need to enable the ADC driver in the kernel. I am using an exact copy of am33xx.dtsi and a edited copy of am335x-bone-common.dtsi from BeagleBoard-DeviceTrees-4.19.x-ti.
What needs added to the device tree to enable the analog inputs?
