Subject: [PATCH 3/3] phy: work around 'phys' references to usb-nop-xceiv
|
||||
devices
|
||||
|
||||
Stefan Wahren reports a problem with a warning fix that was merged
|
||||
for v4.15: we had lots of device nodes with a 'phys' property pointing
|
||||
to a device node that is not compliant with the binding documented in
|
||||
Documentation/devicetree/bindings/phy/phy-bindings.txt
|
||||
|
||||
This generally works because USB HCD drivers that support both the generic
|
||||
phy subsystem and the older usb-phy subsystem ignore most errors from
|
||||
phy_get() and related calls and then use the usb-phy driver instead.
|
||||
|
||||
However, it turns out that making the usb-nop-xceiv device compatible with
|
||||
the generic-phy binding changes the phy_get() return code from -EINVAL to
|
||||
-EPROBE_DEFER, and the dwc2 usb controller driver for bcm2835 now returns
|
||||
-EPROBE_DEFER from its probe function rather than ignoring the failure,
|
||||
breaking all USB support on raspberry-pi when CONFIG_GENERIC_PHY is
|
||||
enabled. The same code is used in the dwc3 driver and the usb_add_hcd()
|
||||
function, so a reasonable assumption would be that many other platforms
|
||||
are affected as well.
|
||||
|
||||
I have reviewed all the related patches and concluded that "usb-nop-xceiv"
|
||||
is the only USB phy that is affected by the change, and since it is by far
|
||||
the most commonly referenced phy, all the other USB phy drivers appear
|
||||
to be used in ways that are are either safe in DT (they don't use the
|
||||
'phys' property), or in the driver (they already ignore -EPROBE_DEFER
|
||||
from generic-phy when usb-phy is available).
|
||||
|
||||
To work around the problem, this adds a special case to _of_phy_get()
|
||||
so we ignore any PHY node that is compatible with "usb-nop-xceiv",
|
||||
as we know that this can never load no matter how much we defer. In the
|
||||
future, we might implement a generic-phy driver for "usb-nop-xceiv"
|
||||
and then remove this workaround.
|
||||
|
||||
Since we generally want older kernels to also want to work with the
|
||||
fixed devicetree files, it would be good to backport the patch into
|
||||
stable kernels as well (3.13+ are possibly affected), even though they
|
||||
don't contain any of the patches that may have caused regressions.
