NVIDIA Tegra20/Tegra30 SLINK controller.
Required properties:
- compatible : should be "nvidia,tegra20-slink", "nvidia,tegra30-slink".
- reg: Should contain SLINK registers location and length.
- interrupts: Should contain SLINK 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@7000d600 {
compatible = "nvidia,tegra20-slink";
reg = <0x7000d600 0x200>;
interrupts = <0 82 0x04>;
spi-max-frequency = <25000000>;
#address-cells = <1>;
#size-cells = <0>;
clocks = <&tegra_car 44>;
resets = <&tegra_car 44>;
reset-names = "spi";
dmas = <&apbdma 16>, <&apbdma 16>;
dma-names = "rx", "tx";
status = "disabled";
