| 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 |
