+NVIDIA Tegra114 SPI controller.
+
+Required properties:
+- compatible : For Tegra114, must contain "nvidia,tegra114-spi".
+ Otherwise, must contain '"nvidia,<chip>-spi", "nvidia,tegra114-spi"' where
+ <chip> is tegra124, tegra132, or tegra210.
+- reg: Should contain SPI registers location and length.
+- interrupts: Should contain SPI interrupts.
+- clock-names : Must include the following entries:
+ - spi
+- resets : Must contain an entry for each entry in reset-names.
+ See ../reset/reset.txt for details.
+- reset-names : Must include the following entries:
+ - spi
+- dmas : Must contain an entry for each entry in clock-names.
+ See ../dma/dma.txt for details.
+- dma-names : Must include the following entries:
+ - rx
+ - tx
+- clocks : Must contain an entry for each entry in clock-names.
+ See ../clocks/clock-bindings.txt for details.
+
+Recommended properties:
+- spi-max-frequency: Definition as per
+ Documentation/devicetree/bindings/spi/spi-bus.txt
+Example:
+
+spi@7000d600 {
+ compatible = "nvidia,tegra114-spi";
+ reg = <0x7000d600 0x200>;
+ interrupts = <0 82 0x04>;
+ spi-max-frequency = <25000000>;
+ #address-cells = <1>;
+ #size-cells = <0>;
+ clocks = <&tegra_car 44>;
+ clock-names = "spi";
+ resets = <&tegra_car 44>;
+ reset-names = "spi";
+ dmas = <&apbdma 16>, <&apbdma 16>;
+ dma-names = "rx", "tx";
+ status = "disabled";
+};
