This approach may resolve this issue for AM335x during power-up, but there still may be an issue during power-down if the AM335x power supply falls faster than the other power supply. It may also violate the same requirement for devices attached to AM335x IOs if they have similar requirements.
Your system must be designed to meet this requirement for all use cases/conditions.
It has been several years since I designed circuit boards, but I was able to resolve this issue by using power supplies designed to track another supply.
