| 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. |

| 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 |
