-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.
-- clocks : Must contain one entry, for the module clock.
-  See ../clocks/clock-bindings.txt for details.
-- 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
-
-Recommended properties:
-- spi-max-frequency: Definition as per
-                     Documentation/devicetree/bindings/spi/spi-bus.txt
