| 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 Cygnus GPIO driver. |
| 32 | |
| 33 | The Broadcom Cygnus SoC has 3 GPIO controllers including the ASIU |
| 34 | GPIO controller (ASIU), the chipCommonG GPIO controller (CCM), and |
| 35 | the always-ON GPIO controller (CRMU/AON). All 3 GPIO controllers are |
| 36 | supported by this driver. |
| 37 | |
| 38 | All 3 Cygnus GPIO controllers support basic PINCONF functions such |
| 39 | as bias pull up, pull down, and drive strength configurations, when |
| 40 | these pins are muxed to GPIO. |
| 41 | |
| 42 | Pins from the ASIU GPIO can be individually muxed to GPIO function, |
| 43 | through interaction with the Cygnus IOMUX controller. |

| 53 | |
| 54 | The Broadcom Cygnus IOMUX driver supports group based IOMUX |
| 55 | configuration, with the exception that certain individual pins |
| 56 | can be overrided to GPIO function |
