GPIO controller (ASIU), the chipCommonG GPIO controller (CCM), and
the always-ON GPIO controller (CRMU/AON). All 3 GPIO controllers are
supported by this driver.

+ All above SoCs GPIO controllers support basic PINCONF functions such
as bias pull up, pull down, and drive strength configurations, when
these pins are muxed to GPIO.
- Pins from the ASIU GPIO can be individually muxed to GPIO function,

+ It provides the framework where pins from the individual GPIO can be
+ individually muxed to GPIO function, through interaction with the
