I hope so ;-)
I mean, it should be easy to add a backward-compatible code that
would make the PHY driver to use the pci-bus old schema if there's
no PHY entry at DT.
However, this is not enough, as the PHY driver won't be loaded/probed
without at least this at hi3660.dtsi:
pcie_phy: pcie-phy@f3f2000 {
compatible = "hisilicon,hi960-pcie-phy";
};
So, some (probably ugly) hack would be needed at pcie-kirin, in order
to make it to manually load and probe the PHY driver, if it
founds (for instance) "phy" reg-name as a pcie-kirin property.
Thanks,
Mauro
