1NVIDIA Tegra114 SPI controller.
2
3Required properties:
4- compatible : should be "nvidia,tegra114-spi".
5- reg: Should contain SPI registers location and length.
6- interrupts: Should contain SPI interrupts.
7- nvidia,dma-request-selector : The Tegra DMA controller's phandle and
8 request selector for this SPI controller.
9- This is also require clock named "spi" as per binding document
10 Documentation/devicetree/bindings/clock/clock-bindings.txt

12Recommended properties:
13- spi-max-frequency: Definition as per
14 Documentation/devicetree/bindings/spi/spi-bus.txt
