One warning is enough. Fixing warnings is good, but what if the property should be there and the bindings are not correct? If you know the answer, please add it to the commit msg. This applies to all your patches. Blind fixing of DTS warnings my produce incorrect results. :( Reviewed-by: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org> Best regards, Krzysztof

Sorry, but the second warning is obvious. It really does not bring any information and better to keep things simple and concise. Concise helps to read/understand the commit. > >> >> Fixing warnings is good, but what if the property should be there and >> the bindings are not correct?

You should always doubt, knowing how incompletely or poorly bindings were written or converted (including the ones I was doing myself). > >> This applies to all your patches.

DTS might be used in other projects - did you test them as well? Best regards, Krzysztof
