+NVIDIA Tegra114 SPI controller.
+
+Required properties:
+- compatible : should be "nvidia,tegra114-spi".
+- reg: Should contain SPI registers location and length.
+- interrupts: Should contain SPI interrupts.
+- clocks : Should contain an entry for SPI clock.
+
+Recommended properties:
+- spi-max-frequency: Definition as per
+ doc/device-tree-bindings/spi/spi-bus.txt
+Example:
