for the BCM281xx SoC family, including BCM11130, BCM11140, BCM11351,

BCM28145, and BCM28155 SoCs. This driver requires the pinctrl

framework. GPIO is provided by a separate GPIO driver.

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