When PINCTRL_BCM63XX is selected, and REGMAP is not selected, Kbuild gives the following warning: WARNING: unmet direct dependencies detected for GPIO_REGMAP Depends on [n]: GPIOLIB [=y] && REGMAP [=n] Selected by [y]: - PINCTRL_BCM63XX [=y] && PINCTRL [=y] This is because PINCTRL_BCM63XX selects GPIO_REGMAP without selecting or depending on REGMAP, despite GPIO_REGMAP depending on REGMAP. This unmet dependency bug was detected by Kismet, a static analysis tool for Kconfig. Please advise if this is not the appropriate solution.

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.
