I spoke too soon: this actually dosn't even build for me.  It's the 
"clocks = <&prci PRCI_CLK_PCIE_AUX>;" line

    Error: arch/riscv/boot/dts/sifive/fu740-c000.dtsi:319.20-21 syntax error
    FATAL ERROR: Unable to parse input tree

I'm not sure what the issue is, I see an anchor for "prci".  Do you mind 
sending along a new version that compiles on top of for-next?  If I need 
the definiton of PRCI_CLK_PCIE_AUX from a PCIe tree then it's probably 
best to just keep the DTS along with the rest of the patches.  IIRC I 
alredy Acked it, but just to be clear

Thanks!
