The binding does not have to specify assigned-clocks, because they are already allowed by core DT schema. On the other hand, fixed assigned-clocks in the binding will not fit different boards or SoCs. Exactly this is the case for Qualcomm SuperSpeed DWC3 USB SoC controller binding, where few boards have different assigned-clocks: ipq8074-hk10-c1.dtb: usb@8cf8800: assigned-clocks: [[5, 131], [5, 132], [5, 133]] is too long sdm660-xiaomi-lavender.dtb: usb@a8f8800: assigned-clocks: [[37, 92], [37, 91], [38, 64]] is too long Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org> --- Documentation/devicetree/bindings/usb/qcom,dwc3.yaml | 9 --------- 1 file changed, 9 deletions(-)
