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>;
