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
Example:
spi@7000c380 {
compatible = "nvidia,tegra20-sflash";
reg = <0x7000c380 0x80>;
interrupts = <0 39 0x04>;
spi-max-frequency = <25000000>;
#address-cells = <1>;
#size-cells = <0>;
clocks = <&tegra_car 43>;
resets = <&tegra_car 43>;
reset-names = "spi";
dmas = <&apbdma 11>, <&apbdma 11>;
dma-names = "rx", "tx";
};
