All 3 GPIO controllers are 87 supported by this driver. 88 89 The Broadcom NSP has two GPIO controllers including the ChipcommonA 90 GPIO, the ChipcommonB GPIO. Later controller is supported by this 91 driver. 92 93 The Broadcom NS2 has two GPIO controller including the CRMU GPIO, 94 the ChipcommonG GPIO. Both controllers are supported by this driver. 95 96 The Broadcom Stingray GPIO controllers are supported by this driver. 97 98 All above SoCs GPIO controllers support basic PINCONF functions such 99 as bias pull up, pull down, and drive strength configurations, when 100 these pins are muxed to GPIO. 101 102 It provides the framework where pins from the individual GPIO can be 103 individually muxed to GPIO function, through interaction with the 104 SoCs IOMUX controller.
