One way is differentiate using different compatible strings fro pcie and sata and use of_device_is_compatible to select a particular path. > > Therefore, in the init/exit routine of phy_ops, I need some way of > identifying that phy_init/exit has been called from PCIe driver or > SATA driver.
In this case you'll be actually registering two different PHYs (each for pcie and sata), so your phy_get should give you the only the appropriate phy.
