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.
