NVIDIA Tegra20 SFLASH controller.



Required properties:

- compatible : should be "nvidia,tegra20-sflash".

- reg: Should contain SFLASH registers location and length.

- interrupts: Should contain SFLASH interrupts.

- nvidia,dma-request-selector : The Tegra DMA controller's phandle and

  request selector for this SFLASH controller.



Recommended properties:

- spi-max-frequency: Definition as per

                     Documentation/devicetree/bindings/spi/spi-bus.txt



Example:



spi@7000d600 {

	compatible = "nvidia,tegra20-sflash";

	reg = <0x7000c380 0x80>;

	interrupts = <0 39 0x04>;

	nvidia,dma-request-selector = <&apbdma 16>;

	spi-max-frequency = <25000000>;

	#address-cells = <1>;

	#size-cells = <0>;

	status = "disabled";
