referring to the last discussion [¹] about what should be handled
where, your last statement is pretty confusing. We might say we
somehow stuck in a loop if i would repost this patch again
and somebody (probably you :]) is telling me to do the opposite again!

If you have a closer look, you can see that we are checking for
valid pdata:

@@ -408,6 +452,9 @@ static int ci_hdrc_probe(struct platform_device *pdev)
                return -ENODEV;
        }

+       if (!ci->platdata->phy_mode)
+               ci->platdata->phy_mode = of_usb_get_phy_mode(dev->of_node);
+

This way we can ensure that platforms without OF still
can use the pdata. _But_ we always fall back to OF in the
core _if_ nobody cared. This should be done with all properties
that are not SoC, but _common_ device specific settings.
