+Cadence Xtensa XTFPGA platform SPI controller.
+
+This simple SPI master controller is built into xtfpga bitstreams and is used
+to control daughterboard audio codec.
+
+Required properties:
+- compatible: should be "cdns,xtfpga-spi".
+- reg: physical base address of the controller and length of memory mapped
+  region.
