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.

34 Say yes here to enable the Broadcom iProc GPIO driver.
35
36 The Broadcom iProc based SoCs- Cygnus, NS2, NSP and Stingray, use
37 same GPIO Controller IP hence this driver could be used for all.
38
39 The Broadcom Cygnus SoC has 3 GPIO controllers including the ASIU
40 GPIO controller (ASIU), the chipCommonG GPIO controller (CCM), and
41 the always-ON GPIO controller (CRMU/AON). All 3 GPIO controllers are
42 supported by this driver.
43
44 The Broadcom NSP has two GPIO controllers including the ChipcommonA
45 GPIO, the ChipcommonB GPIO. Later controller is supported by this
46 driver.
47
48 The Broadcom NS2 has two GPIO controller including the CRMU GPIO,
49 the ChipcommonG GPIO. Both controllers are supported by this driver.
50
51 The Broadcom Stingray GPIO controllers are supported by this driver.
52
53 All above SoCs GPIO controllers support basic PINCONF functions such
54 as bias pull up, pull down, and drive strength configurations, when
55 these pins are muxed to GPIO.
56
57 It provides the framework where pins from the individual GPIO can be
58 individually muxed to GPIO function, through interaction with the
59 SoCs IOMUX controller. This features could be used only on SoCs which
60 support individual pin muxing.

73 configuration, with the exception that certain individual pins
74 can be overridden to GPIO function

86 that can be used for various functions (e.g. SPI, I2C, UART) as well
87 as GPIOs.
