6 bool "Broadcom BCM281xx pinctrl driver"
7 depends on OF && (ARCH_BCM_MOBILE || COMPILE_TEST)
10 select GENERIC_PINCONF
13 Say Y here to support Broadcom BCM281xx pinctrl driver, which is used
14 for the BCM281xx SoC family, including BCM11130, BCM11140, BCM11351,
15 BCM28145, and BCM28155 SoCs. This driver requires the pinctrl
16 framework. GPIO is provided by a separate GPIO driver.
18 config PINCTRL_BCM2835
23 config PINCTRL_CYGNUS_GPIO
24 bool "Broadcom Cygnus GPIO (with PINCONF) driver"
25 depends on OF_GPIO && ARCH_BCM_CYGNUS
26 select GPIOLIB_IRQCHIP
28 select GENERIC_PINCONF
29 default ARCH_BCM_CYGNUS
31 Say yes here to enable the Broadcom Cygnus GPIO driver.
33 The Broadcom Cygnus SoC has 3 GPIO controllers including the ASIU
34 GPIO controller (ASIU), the chipCommonG GPIO controller (CCM), and
35 the always-ON GPIO controller (CRMU/AON). All 3 GPIO controllers are
36 supported by this driver.
38 All 3 Cygnus GPIO controllers support basic PINCONF functions such
39 as bias pull up, pull down, and drive strength configurations, when
40 these pins are muxed to GPIO.
42 Pins from the ASIU GPIO can be individually muxed to GPIO function,
43 through interaction with the Cygnus IOMUX controller.
45 config PINCTRL_CYGNUS_MUX
46 bool "Broadcom Cygnus IOMUX driver"
47 depends on (ARCH_BCM_CYGNUS || COMPILE_TEST)
49 select GENERIC_PINCONF
50 default ARCH_BCM_CYGNUS
52 Say yes here to enable the Broadcom Cygnus IOMUX driver.
54 The Broadcom Cygnus IOMUX driver supports group based IOMUX
55 configuration, with the exception that certain individual pins
56 can be overrided to GPIO function
