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. | |

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. | |
b64333ce RJ |
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 | ||
616043d5 PK |
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 | |
b64333ce RJ |
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 | |

83 | The Broadcom Northstar Plus SoC ChipcommonA GPIO controller is | |
84 | supported by this driver. | |

88 | these pins are muxed to GPIO. | |
