15 Say Y here to support Broadcom BCM281xx pinctrl driver, which is used
16 for the BCM281xx SoC family, including BCM11130, BCM11140, BCM11351,
17 BCM28145, and BCM28155 SoCs. This driver requires the pinctrl
18 framework. GPIO is provided by a separate GPIO driver.

40 Say yes here to enable the Broadcom iProc GPIO driver.
41
42 The Broadcom iProc based SoCs- Cygnus, NS2, NSP and Stingray, use
43 same GPIO Controller IP hence this driver could be used for all.
44
45 The Broadcom Cygnus SoC has 3 GPIO controllers including the ASIU
46 GPIO controller (ASIU), the chipCommonG GPIO controller (CCM), and
47 the always-ON GPIO controller (CRMU/AON). All 3 GPIO controllers are
48 supported by this driver.
49
50 The Broadcom NSP has two GPIO controllers including the ChipcommonA
51 GPIO, the ChipcommonB GPIO. Later controller is supported by this
52 driver.
53
54 The Broadcom NS2 has two GPIO controller including the CRMU GPIO,
55 the ChipcommonG GPIO. Both controllers are supported by this driver.
56
57 The Broadcom Stingray GPIO controllers are supported by this driver.
58
59 All above SoCs GPIO controllers support basic PINCONF functions such
60 as bias pull up, pull down, and drive strength configurations, when
61 these pins are muxed to GPIO.
62
63 It provides the framework where pins from the individual GPIO can be
64 individually muxed to GPIO function, through interaction with the
65 SoCs IOMUX controller. This features could be used only on SoCs which
66 support individual pin muxing.
