acassis opened a new pull request, #18951:
URL: https://github.com/apache/nuttx/pull/18951
## Summary
This driver implements a FT2232H GPIO integration NuttX sim to allow users
to read/write external GPIOs.
It will helps to control external devices using NuttX sim.
The next steps will be adding SPI and I2C integration support.
## Impact
User will be able to use a FT2232H module to read/write external GPIO
## Testing
