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