Revision 1f81f118406774ca65f5a4b1a63ee2478ba826ac authored by Johan Hovold on 23 April 2018, 13:50:01 UTC, committed by Greg Kroah-Hartman on 23 April 2018, 14:02:12 UTC
Set the new HCD flag which prevents USB core from trying to manage our
phys.
This is needed to be able to associate the controller platform device
with the glue device device-tree node on the BBB which uses legacy USB
phys. Otherwise, the generic phy lookup in usb_phy_roothub_init() and
thus HCD registration fails repeatedly with -EPROBE_DEFER (see commit
178a0bce05cb ("usb: core: hcd: integrate the PHY wrapper into the HCD
core")).
Note that a related phy-lookup issue was recently worked around in the
phy core by commit b7563e2796f8 ("phy: work around 'phys' references to
usb-nop-xceiv devices"). Something similar may now be needed for other
USB phys, and in particular if we eventually want to let USB core manage
musb generic phys.
