CONFIG_GPIO_MMIO32¶

(No prompt – not directly user assignable.)

Type: bool

Help¶

This is a driver for accessing a simple, fixed purpose, 32-bit
memory-mapped i/o register using the same APIs as GPIO drivers. This
is useful when an SoC or board has registers that aren't part of a
GPIO IP block and these registers are used to control things that
Zephyr normally expects to be specified using a GPIO pin, e.g. for
driving an LED, or chip-select line for an SPI device.

Direct dependencies¶

GPIO

(Includes any dependencies from ifs and menus.)

Defaults¶

No defaults. Implicitly defaults to n.
