104	  The Broadcom iProc based SoCs- Cygnus, NS2, NSP and Stingray, use
105	  same GPIO Controller IP hence this driver could be used for all.
106
107	  The Broadcom Cygnus SoC has 3 GPIO controllers including the ASIU
108	  GPIO controller (ASIU), the chipCommonG GPIO controller (CCM), and
109	  the always-ON GPIO controller (CRMU/AON). All 3 GPIO controllers are
110	  supported by this driver.
111
112	  The Broadcom NSP has two GPIO controllers including the ChipcommonA
113	  GPIO, the ChipcommonB GPIO. Later controller is supported by this
114	  driver.
115
116	  The Broadcom NS2 has two GPIO controller including the CRMU GPIO,
117	  the ChipcommonG GPIO. Both controllers are supported by this driver.
118
119	  The Broadcom Stingray GPIO controllers are supported by this driver.
120
121	  All above SoCs GPIO controllers support basic PINCONF functions such
122	  as bias pull up, pull down, and drive strength configurations, when
123	  these pins are muxed to GPIO.
124
125	  It provides the framework where pins from the individual GPIO can be
126	  individually muxed to GPIO function, through interaction with the
127	  SoCs IOMUX controller. This features could be used only on SoCs which
128	  support individual pin muxing.
