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.

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

65 depends on (ARCH_BCM_CYGNUS || COMPILE_TEST)
68 select GENERIC_PINCONF
69 default ARCH_BCM_CYGNUS
71 Say yes here to enable the Broadcom Cygnus IOMUX driver.
73 The Broadcom Cygnus IOMUX driver supports group based IOMUX
74 configuration, with the exception that certain individual pins
75 can be overridden to GPIO function

84 Say yes here to enable the Broadcom NS SoC pins driver.
86 The Broadcom Northstar pins driver supports muxing multi-purpose pins
87 that can be used for various functions (e.g. SPI, I2C, UART) as well

98 Say yes here to enable the Broadcom NSP GPIO driver.
100 The Broadcom Northstar Plus SoC ChipcommonA GPIO controller is
101 supported by this driver.
103 The ChipcommonA GPIO controller support basic PINCONF functions such
104 as bias pull up, pull down, and drive strength configurations, when
105 these pins are muxed to GPIO.
