- 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.
