We do not advertise websites, unless it brings some value. Agreed. I've removed the link in v3. > Drop bootargs, why do you need empty ones anyway? The empty bootargs is not needed. I've removed it. > just "phy" or is there phy-1? There is only one USB PHY on this board. I've renamed the node to "phy". Thanks for the review! Pufan Jin
