Hey, Sorry for the broken tag, will fix on a resend. As for the naming, if there is any reason for them to be named qm_* it's totally fine, I'll revert it and only touch the clock names. I changed them because comparing with lvds1, those ones do not contain the qm_ prefix and I don't see how this dtsi relates specifically to the imx8qm, since it is a imx8-ss... and not imx8qm-ss... I didn't quite get the question about the nodes. Could you elaborate?
