I've re-checked it - sorry for disinfo.

PHY devices are created, but omap_device_fail_pm_domain is assigned to them.
As result Runtime PM is not working any more.


[    0.592501] platform 4a094000.pciephy: Cannot lookup hwmod 'pcie1-phy'
[    0.597510] pinctrl-single 4a003400.pinmux: 281 pins at pa fc003400 size 1124
[    0.602794] ti-pipe3 4a094000.pciephy: _od_fail_runtime_resume: FIXME: missing hwmod/omap_dev info

When ti,hwmods is not present PCI PHY will be added as regular Platform device
and Runtime PM will work again.
