I'm trying to understand whether this is due to the expected routing through different trees/maintainers or if there is another consideration. > Shawn > >> arm64: dts: qcom: nord: Add iris video node >> arm64: dts: qcom: nord-ride-embedded: Enable iris video codec node >> arm64: dts: qcom: nord-rrd: Enable iris video codec node >> >> .../bindings/media/qcom,glymur-iris.yaml | 6 +- >> arch/arm64/boot/dts/qcom/nord-embedded.dtsi | 114 +++++++++++++++++++++ >> arch/arm64/boot/dts/qcom/nord-ride-embedded.dts | 6 ++ >> arch/arm64/boot/dts/qcom/nord-rrd.dts | 6 ++ >> 4 files changed, 131 insertions(+), 1 deletion(-)
