	  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 Cygnus GPIO driver.

	  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.

	  All 3 Cygnus GPIO controllers support basic PINCONF functions such
	  as bias pull up, pull down, and drive strength configurations, when
	  these pins are muxed to GPIO.

	  Pins from the ASIU GPIO can be individually muxed to GPIO function,
	  through interaction with the Cygnus IOMUX controller.

config PINCTRL_CYGNUS_MUX
	bool "Broadcom Cygnus IOMUX driver"
	depends on (ARCH_BCM_CYGNUS || COMPILE_TEST)
	select PINMUX
	select GENERIC_PINCONF
	default ARCH_BCM_CYGNUS
	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 overrided to GPIO function
