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

  31           Say yes here to enable the Broadcom iProc GPIO driver.
  32
  33           The Broadcom iProc based SoCs- Cygnus, NS2, NSP and Stingray, use
  34           same GPIO Controller IP hence this driver could be used for all.
  35
  36           The Broadcom Cygnus SoC has 3 GPIO controllers including the ASIU
  37           GPIO controller (ASIU), the chipCommonG GPIO controller (CCM), and
  38           the always-ON GPIO controller (CRMU/AON). All 3 GPIO controllers are
  39           supported by this driver.
  40
  41           The Broadcom NSP has two GPIO controllers including the ChipcommonA
  42           GPIO, the ChipcommonB GPIO. Later controller is supported by this
  43           driver.
  44
  45           The Broadcom NS2 has two GPIO controller including the CRMU GPIO,
  46           the ChipcommonG GPIO. Both controllers are supported by this driver.
  47
  48           The Broadcom Stingray GPIO controllers are supported by this driver.
  49
  50           All above SoCs GPIO controllers support basic PINCONF functions such
  51           as bias pull up, pull down, and drive strength configurations, when
  52           these pins are muxed to GPIO.
  53
  54           It provides the framework where pins from the individual GPIO can be
  55           individually muxed to GPIO function, through interaction with the
  56           SoCs IOMUX controller. This features could be used only on SoCs which
  57           support individual pin muxing.

  67
  68           The Broadcom Cygnus IOMUX driver supports group based IOMUX
  69           configuration, with the exception that certain individual pins
  70           can be overrided to GPIO function

  81
  82           The Broadcom Northstar Plus SoC ChipcommonA GPIO controller is
  83           supported by this driver.
  84
  85           The ChipcommonA GPIO controller support basic PINCONF functions such
  86           as bias pull up, pull down, and drive strength configurations, when
  87           these pins are muxed to GPIO.
