15 Say Y here to support Broadcom BCM281xx pinctrl driver, which is used
16 for the BCM281xx SoC family, including BCM11130, BCM11140, BCM11351,
17 BCM28145, and BCM28155 SoCs. This driver requires the pinctrl
18 framework. GPIO is provided by a separate GPIO driver.

102 Say yes here to enable the Broadcom iProc GPIO driver.
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.
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.
112 The Broadcom NSP has two GPIO controllers including the ChipcommonA
113 GPIO, the ChipcommonB GPIO. Later controller is supported by this
116 The Broadcom NS2 has two GPIO controller including the CRMU GPIO,
117 the ChipcommonG GPIO. Both controllers are supported by this driver.
119 The Broadcom Stingray GPIO controllers are supported by this driver.
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.
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.
