Why doesn't that patch update this clock cell then?

This can be split from the patch to fix just the name in one patch and then add the pcie1_lane phandle in the next patch. That way new features aren't being mixed together with the string fix.

Looks like Bjorn already picked it up so that answers my question.

In addition, I see that Rob sent a patch[1] that fixes the interrupt-map in the pcie node. Can you send a similar patch for sc7280? It looks wrong. We need another two zeroes like on sdm845.dtsi. So please resend this series with three patches and the appropriate Fixes tags.
