GPIO default state

[noblepepper]

Is a gpio in a certain state (high or low) on the rt5350 if it is unconnected? I have been playing with gpio0 and swear it was low unless I pulled it high originally. Now it seems to be high unless I pull it low.

This is able to fix by code. In fact, GPIO default is low, but when uboot up, it will make gpio go high(you can check uboot source, one asm file). then after linux runs, the state will be low again.
