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

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

  72           configuration, with the exception that certain individual pins
  73           can be overridden to GPIO function

  86           supported by this driver.
