CONFIG_PINCTRL_CYGNUS_GPIO: Broadcom Cygnus GPIO (with PINCONF) driver

General informations

The Linux kernel configuration item CONFIG_PINCTRL_CYGNUS_GPIO:

• prompt: Broadcom Cygnus GPIO (with PINCONF) driver
• type: bool
• depends on: CONFIG_OF_GPIO && CONFIG_ARCH_BCM_CYGNUS
• defined in drivers/pinctrl/bcm/Kconfig
• found in Linux kernels: 4.1–4.4

Help text

Say yes here to enable the Broadcom Cygnus GPIO driver.

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.

All 3 Cygnus GPIO controllers support basic PINCONF functions such as bias pull up, pull down, and drive strength configurations, when these pins are muxed to GPIO.

Pins from the ASIU GPIO can be individually muxed to GPIO function, through interaction with the Cygnus IOMUX controller.
