PS4, Line 9: The GPP_F23/ISH_GP_9A pin receives the lid open/close signal from
           : SMC_LID. This pin is not utilized in the AP firmware stack; however, the
           : ISH firmware requires this signal for its tablet mode support.
           : Therefore, we configure this pin as an ISH GPIO.
> The right side looks a little unaligned. It’d be great if you re-flowed.
