| 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. |
