| | 32 | Say yes here to enable the Broadcom iProc GPIO driver. |
| | 33 | |
| | 34 | The Broadcom iProc based SoCs- Cygnus, NS2, NSP and Stingray, use |
| | 35 | same GPIO Controller IP hence this driver could be used for all. |
| | 36 | |
| | 37 | The Broadcom Cygnus SoC has 3 GPIO controllers including the ASIU |
| | 38 | GPIO controller (ASIU), the chipCommonG GPIO controller (CCM), and |
| | 39 | the always-ON GPIO controller (CRMU/AON). All 3 GPIO controllers are |
| | 40 | supported by this driver. |
| | 41 | |
| | 42 | The Broadcom NSP has two GPIO controllers including the ChipcommonA |
| | 43 | GPIO, the ChipcommonB GPIO. Later controller is supported by this |
| | 44 | driver. |
| | 45 | |
| | 46 | The Broadcom NS2 has two GPIO controller including the CRMU GPIO, |
| | 47 | the ChipcommonG GPIO. Both controllers are supported by this driver. |
| | 48 | |
| | 49 | The Broadcom Stingray GPIO controllers are supported by this driver. |
| | 50 | |
| | 51 | All above SoCs GPIO controllers support basic PINCONF functions such |
| | 52 | as bias pull up, pull down, and drive strength configurations, when |
| | 53 | these pins are muxed to GPIO. |
| | 54 | |
| | 55 | It provides the framework where pins from the individual GPIO can be |
| | 56 | individually muxed to GPIO function, through interaction with the |
| | 57 | SoCs IOMUX controller. This features could be used only on SoCs which |
| | 58 | support individual pin muxing. |

| | 68 | |
| | 69 | The Broadcom Cygnus IOMUX driver supports group based IOMUX |
| | 70 | configuration, with the exception that certain individual pins |
| | 71 | can be overrided to GPIO function |

| | 84 | supported by this driver. |
| | 85 | |
| | 86 | The ChipcommonA GPIO controller support basic PINCONF functions such |
