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.

Pramod Kumar616043d2015-11-19 09:22:19 +053033 Say yes here to enable the Broadcom iProc GPIO driver.
34
35 The Broadcom iProc based SoCs- Cygnus, NS2, NSP and Stingray, use
36 same GPIO Controller IP hence this driver could be used for all.
Ray Juib64333c2015-03-09 13:45:00 -070037
38 The Broadcom Cygnus SoC has 3 GPIO controllers including the ASIU
39 GPIO controller (ASIU), the chipCommonG GPIO controller (CCM), and
40 the always-ON GPIO controller (CRMU/AON). All 3 GPIO controllers are
41 supported by this driver.
42
Pramod Kumar616043d2015-11-19 09:22:19 +053043 The Broadcom NSP has two GPIO controllers including the ChipcommonA
44 GPIO, the ChipcommonB GPIO. Later controller is supported by this
45 driver.
46
47 The Broadcom NS2 has two GPIO controller including the CRMU GPIO,
48 the ChipcommonG GPIO. Both controllers are supported by this driver.
49
50 The Broadcom Stingray GPIO controllers are supported by this driver.
51
52 All above SoCs GPIO controllers support basic PINCONF functions such
Ray Juib64333c2015-03-09 13:45:00 -070053 as bias pull up, pull down, and drive strength configurations, when
54 these pins are muxed to GPIO.
55
Pramod Kumar616043d2015-11-19 09:22:19 +053056 It provides the framework where pins from the individual GPIO can be
57 individually muxed to GPIO function, through interaction with the
58 SoCs IOMUX controller. This features could be used only on SoCs which
59 support individual pin muxing.
