It was suggested to follow the linux gpio standards, and separate the pin controller functionality from the gpio functionality. Instead of creating a followup v2 patch, I am creating a new series because there are 2 drivers (2 patches) involved now: 1) NVIDIA BlueField-3 GPIO driver as front end 2) NVIDIA BlueField-3 pin controller as back end Moved the FW_CONTROL_CLEAR/SET code to the pin controller so that there are 2 GPIO mux selectors: 1) default hardware functionality 2) gpio functionality where software can control the GPIO value when the direction is set to output. Removed support to the GPIO sysfs since its use is deprecated and risky. Instead, used libgpiod to test this code.
