You cannot test the binding different way. You can review it, that it matches datasheet. You can test the DTS on the physical hardware, but not the binding. So if this is equal to "building" we do not act like: "I built a kernel, so add my Tested-by tag". Maybe this was added to cover letter, so the tag populated here as well. > --- > .../devicetree/bindings/display/renesas,du.yaml | 52 ++++++++++++++++++++-- > 1 file changed, 48 insertions(+), 4 deletions(-) Reviewed-by: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org> Best regards, Krzysztof

Yes, Geert gave a tested-by for the series, so b4 applied it to all patches. I'll drop the Tested-by from this and the next patches. Tomi
