+

+ GPIO, the ChipcommonB GPIO. Later controller is supported by this
+ driver.
+
+ The Broadcom NS2 has two GPIO controller including the CRMU GPIO,
+ the ChipcommonG GPIO. Both controllers are supported by this driver.
+
+ The Broadcom Stingray 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.
+
+ It provides the framework where pins from the individual GPIO can be
+ individually muxed to GPIO function, through interaction with the
+ SoCs IOMUX controller. This features could be used only on SoCs which
+ support individual pin muxing.
