7 title: Analog Devices AXI SPI Engine Controller
10 The AXI SPI Engine controller is part of the SPI Engine framework[1] and
11 allows memory mapped access to the SPI Engine control bus. This allows it
12 to be used as a general purpose software driven SPI controller as well as
13 some optional advanced acceleration and offloading capabilities.
