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
23 select GENERIC_PINCONF
24 select GPIOLIB_IRQCHIP
26 config PINCTRL_IPROC_GPIO
27 bool "Broadcom iProc GPIO (with PINCONF) driver"
28 depends on OF_GPIO && (ARCH_BCM_IPROC || COMPILE_TEST)
29 select GPIOLIB_IRQCHIP
31 select GENERIC_PINCONF
32 default ARCH_BCM_IPROC
34 Say yes here to enable the Broadcom iProc GPIO driver.
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.
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.
44 The Broadcom NSP has two GPIO controllers including the ChipcommonA
45 GPIO, the ChipcommonB GPIO. Later controller is supported by this
48 The Broadcom NS2 has two GPIO controller including the CRMU GPIO,
49 the ChipcommonG GPIO. Both controllers are supported by this driver.
51 The Broadcom Stingray GPIO controllers are supported by this driver.
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.
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.
62 config PINCTRL_CYGNUS_MUX
63 bool "Broadcom Cygnus IOMUX driver"
64 depends on (ARCH_BCM_CYGNUS || COMPILE_TEST)
67 select GENERIC_PINCONF
68 default ARCH_BCM_CYGNUS
70 Say yes here to enable the Broadcom Cygnus IOMUX driver.
72 The Broadcom Cygnus IOMUX driver supports group based IOMUX
73 configuration, with the exception that certain individual pins
74 can be overridden to GPIO function
77 bool "Broadcom Northstar pins driver"
78 depends on OF && (ARCH_BCM_5301X || COMPILE_TEST)
80 select GENERIC_PINCONF
81 default ARCH_BCM_5301X
83 Say yes here to enable the Broadcom NS SoC pins driver.
85 The Broadcom Northstar pins driver supports muxing multi-purpose pins
86 that can be used for various functions (e.g. SPI, I2C, UART) as well
89 config PINCTRL_NSP_GPIO
90 bool "Broadcom NSP GPIO (with PINCONF) driver"
91 depends on OF_GPIO && (ARCH_BCM_NSP || COMPILE_TEST)
92 select GPIOLIB_IRQCHIP
94 select GENERIC_PINCONF
97 Say yes here to enable the Broadcom NSP GPIO driver.
99 The Broadcom Northstar Plus SoC ChipcommonA GPIO controller is
100 supported by this driver.
102 The ChipcommonA GPIO controller support basic PINCONF functions such
103 as bias pull up, pull down, and drive strength configurations, when
104 these pins are muxed to GPIO.
106 config PINCTRL_NS2_MUX
107 bool "Broadcom Northstar2 pinmux driver"
109 depends on ARCH_BCM_IPROC || COMPILE_TEST
111 select GENERIC_PINCONF
112 default ARM64 && ARCH_BCM_IPROC
114 Say yes here to enable the Broadcom NS2 MUX driver.
116 The Broadcom Northstar2 IOMUX driver supports group based IOMUX
119 config PINCTRL_NSP_MUX
120 bool "Broadcom NSP IOMUX driver"
121 depends on (ARCH_BCM_NSP || COMPILE_TEST)
124 select GENERIC_PINCONF
127 Say yes here to enable the Broadcom NSP SOC IOMUX driver.
129 The Broadcom Northstar Plus IOMUX driver supports pin based IOMUX
130 configuration, with certain individual pins can be overridden
