| 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. |
