IMO, just drop it. Regarding this ^^^, you're right, so we avoid to add "fsl,imx-osc", but at this point, does it make sense we create a patchset to remove it from the other .dts(i) files that use it? And same goes for "fsl,imx-ckil", "fsl,imx-ckih1", "fsl,imx-ckih2"? I see that those try to repeat the name of the node itself so they are useless. If you say so I send a patchset for that. Thank you Best regards
