Node names should be generic.
https://devicetree-specification.readthedocs.io/en/latest/chapter2-devicetree-basics.html#generic-names-recommendation
Thank Krzysztof,
I think these node names should be "fan-i2c-0" and "fan-i2c-1". Do you
have any other idea ?
i2c-0 is not generic. This should be either fan or fan-controller,
depending what this is.
Thank Krzysztof! I will update node name is "fan-controller" in PATCH v2.
+ compatible = "maxim,max31790";
Unfortunately the compatible is undocumented.
Please run scripts/checkpatch.pl and fix reported warnings.
Best regards,
Krzysztof
Yes Krzysztof,
This compatible has not yes documented.
Should I push a document for max31790 to
./Documentation/devicetree/bindings/ or ask to maintainer (Guenter Roeck
<linux@xxxxxxxxxxxx> or Jean Delvare <jdelvare@xxxxxxxx>) ?
Check on lore.kernel.org if there is ongoing work. If there is no, then
please submit new the bindings (in DT schema). Maintainers are not for
writing your code, so it's you or some other developer who should do it.
Best regards,
Krzysztof
Thank Krzysztof!
I checked on lore.kernel.org but no submit is in-progress for that. I'll
submit new the binding document for max31790.
Now, Do I need to remove the "[PATCH 2/4] ARM: dts: aspeed: mtmitchell:
Add I2C Fan" from PATCH v2?
And will push again "ARM: dts: aspeed: mtmitchell: Add I2C Fan" commit
once max31790 binding document was available upstream.
