Not everything in the device tree is in the .dts file. U-boot or other firmware can modify the device tree before passing it to the kernel. It may not always be possible to update the device tree without also updating the firmware. I already know of changes that I'd like to make to the lite5200 tree which I know will break u-boot. That isn't the situation in this particular case, but we must always keep it in mind. Cheers, g. -- Grant Likely, B.Sc., P.Eng. Secret Lab Technologies Ltd.
