Enable setting FT4232 ports as GPIO

costinctin · wangxiaoningnxp · commit 062c1b74150b · 2026-05-07T16:42:44.000+08:00
Enable setting FT4232 ports as GPIO.
Aside from port B that is used for I2C communication, port C
or port D might be used as GPIOs. This is true for S32N79RDB
that has TP32, TP30, TP29 and TP27 connected to Port C and D.
