126 Say yes here to enable the Broadcom iProc GPIO driver.
128 The Broadcom iProc based SoCs- Cygnus, NS2, NSP and Stingray, use
129 same GPIO Controller IP hence this driver could be used for all.
131 The Broadcom Cygnus SoC has 3 GPIO controllers including the ASIU
132 GPIO controller (ASIU), the chipCommonG GPIO controller (CCM), and
133 the always-ON GPIO controller (CRMU/AON). All 3 GPIO controllers are
134 supported by this driver.
136 The Broadcom NSP has two GPIO controllers including the ChipcommonA
137 GPIO, the ChipcommonB GPIO. Later controller is supported by this
140 The Broadcom NS2 has two GPIO controller including the CRMU GPIO,
141 the ChipcommonG GPIO. Both controllers are supported by this driver.
143 The Broadcom Stingray GPIO controllers are supported by this driver.
145 All above SoCs GPIO controllers support basic PINCONF functions such
146 as bias pull up, pull down, and drive strength configurations, when
147 these pins are muxed to GPIO.
149 It provides the framework where pins from the individual GPIO can be
150 individually muxed to GPIO function, through interaction with the
151 SoCs IOMUX controller. This features could be used only on SoCs which
152 support individual pin muxing.
