It seems to me that that patch does two things at a time:
1. Fixes invalid fourth clock-names entry.
2. Fixes the fsl,imx8mm-pcie device having the "pcie_aux" clock name
required instead of "pcie_phy".

My patch does only the first part. What about moving my patch to that
series and converting the Marek' patch to being applicable on top of
it and fixing the imx8mm part only? That seems reasonable.
