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

+	  Say yes here to enable the Broadcom iProc GPIO driver.
+
+	  The Broadcom iProc based SoCs- Cygnus, NS2, NSP and Stingray, use
+	  same GPIO Controller IP hence this driver could be used for all.
+
+	  The Broadcom Cygnus SoC has 3 GPIO controllers including the ASIU
+	  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.
+
+	  The Broadcom NSP has two GPIO controllers including the ChipcommonA
+	  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.

+	help
+	  Say yes here to enable the Broadcom Cygnus IOMUX driver.
+
+	  The Broadcom Cygnus IOMUX driver supports group based IOMUX
+	  configuration, with the exception that certain individual pins
+	  can be overridden to GPIO function

+	help
+	  Say yes here to enable the Broadcom NS SoC pins driver.
+
+	  The Broadcom Northstar pins driver supports muxing multi-purpose pins
+	  that can be used for various functions (e.g. SPI, I2C, UART) as well
+	  as GPIOs.
+
+config PINCTRL_NSP_GPIO

+
+	  The Broadcom Northstar Plus SoC ChipcommonA GPIO controller is
+	  supported by this driver.
+
+	  The ChipcommonA GPIO controller support basic PINCONF functions such
+	  as bias pull up, pull down, and drive strength configurations, when
+	  these pins are muxed to GPIO.
