TPS65218: Open drain output buffer IC is required on WAKEUP, INTn and PGOOD pin of TPS65218

HI All,

Is it necessary to use open drain buffer in between WAKEUP, INTn and PGOOD signal and Am437X 

Can PMIC drive the logic high and low on the above-mentioned pin till the AM437X iC which is 30mm far from the PMIC

Kindly revert back asap

thanks in advance
