PS1, Line 29: PAD_NC(GPIO_138, UP_20K),
It seems to me there is no one leveraged GPIO_138?

PS1, Line 32: PAD_CFG_GPO_IOSSTATE_IOSTERM(GPIO_140, 0, DEEP, NONE, Tx1RxDCRx0, DISPUPD),
I checked the original review comment but it is still wried to me that
- you put default state as low ->NMOS -> high then PEN_RESET_ODL is not active so chip is not in RESET state (???) during the boot up.
- you set IOSTATE to high -> NMOS -> low so PEN_RESET_ODL is in active which hold chip is RESET state.
