0118
0119 The Broadcom iProc based SoCs- Cygnus, NS2, NSP and Stingray, use
0120 same GPIO Controller IP hence this driver could be used for all.
0121
0122 The Broadcom Cygnus SoC has 3 GPIO controllers including the ASIU
0123 GPIO controller (ASIU), the chipCommonG GPIO controller (CCM), and
0124 the always-ON GPIO controller (CRMU/AON). All 3 GPIO controllers are
0125 supported by this driver.
0126
0127 The Broadcom NSP has two GPIO controllers including the ChipcommonA
0128 GPIO, the ChipcommonB GPIO. Later controller is supported by this
0129 driver.
0130
0131 The Broadcom NS2 has two GPIO controller including the CRMU GPIO,
0132 the ChipcommonG GPIO. Both controllers are supported by this driver.
0133
0134 The Broadcom Stingray GPIO controllers are supported by this driver.
0135
0136 All above SoCs GPIO controllers support basic PINCONF functions such
0137 as bias pull up, pull down, and drive strength configurations, when
0138 these pins are muxed to GPIO.
0139
0140 It provides the framework where pins from the individual GPIO can be
0141 individually muxed to GPIO function, through interaction with the
0142 SoCs IOMUX controller. This features could be used only on SoCs which
0143 support individual pin muxing.
