5 config PINCTRL_BCM281XX
6 bool "Broadcom BCM281xx pinctrl driver"
7 depends on OF && (ARCH_BCM_MOBILE || COMPILE_TEST)
10 select GENERIC_PINCONF
12 default ARCH_BCM_MOBILE
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.
19 config PINCTRL_BCM2835
24 config PINCTRL_IPROC_GPIO
25 bool "Broadcom iProc GPIO (with PINCONF) driver"
26 depends on OF_GPIO && (ARCH_BCM_IPROC || COMPILE_TEST)
27 select GPIOLIB_IRQCHIP
29 select GENERIC_PINCONF
30 default ARCH_BCM_IPROC
32 Say yes here to enable the Broadcom iProc GPIO driver.
34 The Broadcom iProc based SoCs- Cygnus, NS2, NSP and Stingray, use
35 same GPIO Controller IP hence this driver could be used for all.
37 The Broadcom Cygnus SoC has 3 GPIO controllers including the ASIU
38 GPIO controller (ASIU), the chipCommonG GPIO controller (CCM), and
39 the always-ON GPIO controller (CRMU/AON). All 3 GPIO controllers are
40 supported by this driver.
42 The Broadcom NSP has two GPIO controllers including the ChipcommonA
43 GPIO, the ChipcommonB GPIO. Later controller is supported by this
46 The Broadcom NS2 has two GPIO controller including the CRMU GPIO,
47 the ChipcommonG GPIO. Both controllers are supported by this driver.
49 The Broadcom Stingray GPIO controllers are supported by this driver.
51 All above SoCs GPIO controllers support basic PINCONF functions such
52 as bias pull up, pull down, and drive strength configurations, when
53 these pins are muxed to GPIO.
55 It provides the framework where pins from the individual GPIO can be
56 individually muxed to GPIO function, through interaction with the
57 SoCs IOMUX controller. This features could be used only on SoCs which
58 support individual pin muxing.
60 config PINCTRL_CYGNUS_MUX
61 bool "Broadcom Cygnus IOMUX driver"
62 depends on (ARCH_BCM_CYGNUS || COMPILE_TEST)
64 select GENERIC_PINCONF
65 default ARCH_BCM_CYGNUS
67 Say yes here to enable the Broadcom Cygnus IOMUX driver.
69 The Broadcom Cygnus IOMUX driver supports group based IOMUX
70 configuration, with the exception that certain individual pins
71 can be overrided to GPIO function
73 config PINCTRL_NSP_GPIO
74 bool "Broadcom NSP GPIO (with PINCONF) driver"
75 depends on OF_GPIO && (ARCH_BCM_NSP || COMPILE_TEST)
76 select GPIOLIB_IRQCHIP
78 select GENERIC_PINCONF
81 Say yes here to enable the Broadcom NSP GPIO driver.
83 The Broadcom Northstar Plus SoC ChipcommonA GPIO controller is
84 supported by this driver.
86 The ChipcommonA GPIO controller support basic PINCONF functions such
87 as bias pull up, pull down, and drive strength configurations, when
88 these pins are muxed to GPIO.
90 config PINCTRL_NS2_MUX
91 bool "Broadcom Northstar2 pinmux driver"
93 depends on ARCH_BCM_IPROC || COMPILE_TEST
95 select GENERIC_PINCONF
96 default ARM64 && ARCH_BCM_IPROC
98 Say yes here to enable the Broadcom NS2 MUX driver.
100 The Broadcom Northstar2 IOMUX driver supports group based IOMUX
103 config PINCTRL_NSP_MUX
104 bool "Broadcom NSP IOMUX driver"
105 depends on (ARCH_BCM_NSP || COMPILE_TEST)
107 select GENERIC_PINCONF
110 Say yes here to enable the Broadcom NSP SOC IOMUX driver.
112 The Broadcom Northstar Plus IOMUX driver supports pin based IOMUX
113 configuration, with certain individual pins can be overridden
