Public bug reported:
SRU Justification:
[Impact]
* Support GPIO driver for BlueField-3 SoCs.
[Fix]
* Support GPIO driver for BlueField-3 SoCs.
* Allows user to alter GPIO value when direction is set to output
* Support configuring GPIOs as interrupts for dependent drivers such as
pwr-mlxbf and mlxbf-gige
[Test Case]
* At the moment, this driver can only be tested internally on palladium and via
the ARM simulator.
* This driver only loaded on BF3 platforms so has no impact on older platforms
such as BF2 and BF1.
[Regression Potential]
* Code will need to be tested once real HW is ready (bringup)
[Other]
* This driver is in the process of being upstreamed. This code is likely to
change depending on feedback we receive from maintainers. But the upstreaming
process is long and we need to have this code to be available before
BlueField-3 bringup.
