ADPD105 -- GPIO Pins Input Levels

In the datasheet of ADPD105, there are some conflicted information I want to ask about.

 

If you check Table.5 at page 9, GPIO pins input level can go as high as 3.6V. However, If you check Table.8 at page 12 and the first paragraph at page 30, it is stated that GPIO cannot take input levels higher than 2.2V and should be given 1.8V as input HIGH.

 

Clearly there is a contradiction in the information you are representing and I would like to know if I need a level translator or not as I would like drive GPIO pins 3.3V, same as my I2C bus.
