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.

31	  Say yes here to enable the Broadcom Cygnus GPIO driver.
32
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.
37
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.
41
42	  Pins from the ASIU GPIO can be individually muxed to GPIO function,
43	  through interaction with the Cygnus IOMUX controller.

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
