VSC devicetree plugin erroneously reports errors

[Allen]

Hello,

The VSC plugin is showing squiggles for SPI related nodes which are valid. (compile with no errors)

Here is an example:

Here is the error message

Thanks

The devicetree extension is a bit more strict than the compiler, since what you're trying to do is technically not allowed in the devicetree-language.

You need to add a compatible field for both the spi1 as well as the child node.

For spi1 you should add compatible = "nordic,nrf-spim". Our developer has created a PR regarding this https://github.com/zephyrproject-rtos/zephyr/pull/41102.

For the SPI child node, check out the possible compatibles in <ncs location>/zephyr/dts/bindings/sensor. For example:

https://github.com/nrfconnect/sdk-zephyr/blob/v2.7.0-ncs1-rc2/boards/arm/thingy53_nrf5340/thingy53_nrf5340_common.dts#L168 

https://github.com/nrfconnect/sdk-nrf/blob/v1.8.0-rc2/boards/arm/thingy91_nrf9160/thingy91_nrf9160_common.dts#L115

Best regards,

Simon

Simon, could you please provide some more details here? I maintain the zephyr devicetree tooling, and I don't see anything inherently wrong with the above example from a DT language perspective.

Hi Marti.

I got this information from an internal in Nordic. Maybe I misunderstood what he was saying. I'll talk to him tomorrow and clarify.
