Hi Guillaume,

Not sure what I did to get CC'd on this, but since I'm here...

Please see the bisection report below about usb2phy failing to
probe on rk3399-gru-kevin.

Reports aren't automatically sent to the public while we're
trialing new bisection features on kernelci.org but this one
looks valid.

The bisection was run in the Renesas tree but the same regression
is present in mainline for both usb2phy0 and usb2phy1 devices:

https://linux.kernelci.org/test/plan/id/6100af012344eef9b85018f3/
https://linux.kernelci.org/test/case/id/6100af012344eef9b85018fa/

I don't see any errors in the logs, it looks like the driver is
just not probing.

What's the actual testcase for "rockchip-usb2phy0-probed"? If it's looking for a hard-coded path like "/sys/bus/platform/devices/ff770000.syscon:usb2-phy@e450/driver" then it can be expected to fail, since changing the node name is reflected in the device name.

Robin.

Best wishes,
Guillaume

commit 8c3d64251ac5c5a3d10364f6b07d3603ac1e7b4a
Author: Johan Jonker <jbx6244@xxxxxxxxx>
Date: Tue Jun 1 18:47:59 2021 +0200

arm64: dts: rockchip: rename nodename for phy-rockchip-inno-usb2
The pattern: "^(|usb-|usb2-|usb3-|pci-|pcie-|sata-)phy(@[0-9a-f,]+)*$"
in phy-provider.yaml has required "#phy-cells" for phy nodes.
The "phy-cells" in rockchip-inno-usb2 nodes are located in subnodes.
Rename the nodename to pattern "usb2phy@[0-9a-f]+$" to prevent
notifications.
