Hi,
i noticed that upper usb-Port (otg) is broken on my Bananapi R2Pro with 5.19-rc1, works with 5.18.0
this port is a usb3 (xhci) port which includes an usb2-phy and should support otg, but i still want
to use it in host-only mode (USB-A socket).
already tried setting dr_mode in dts back to "host" as this was changed in rk356x.dtsi by this commit:
bc405bb3eeee 2022-04-25 arm64: dts: rockchip: enable otg/drd operation of usb_host0_xhci in rk356x
i see no error in dmesg and usb-controllers seem to be initialized completely (visible in lsusb).
r2pro has ID-Pin not connected, so i tried also peters Patch without success :(
0901c01f8ac4 2022-06-21 phy: rockchip-inno-usb2: Sync initial otg state
so i tried bisect which seems to point to wrong commit (not related)...

have not replaced dtb while testing to exclude these changes
i looked through commits between good-bad-change and there are some for the rockchip-inno-usb2-phy where i guess the problem is located
git log --oneline 46ee6bcac9838b7f74ff91f9cf38511c901ea9c5..dc6a7effb48e7267c9f1314e3aa8cfe539bd6096
issue is maybe extcon (pointing to the usb2-phy) related as 5.18 uses extcon for this port.
Tried to find something in sysfs/debugfs, but without success.
maybe anyone has an idea? anything i can try/readout (sysfs/debugfs).
regards Frank
Hi,
traced it down with manual reverts to this one:
commit 6a98df08ccd55e87947d253b19925691763e755c
phy: rockchip-inno-usb2: Fix muxed interrupt support
luckily i can revert only this and now upper usb-port works again
@samuel: have you an idea how to fix your problem without breaking my board? :)
@greg/Vinod: maybe we can add a revert of this in mainline till issue is resolved?
regards Frank

I don't know what you're running, but with the standard arm64
defconfig w/ all rockchip stuff built in, I have no issues here on
5.19.
Note, the following changes are necessary to the 5.19 dts here:
Remove the extcon from usb_host0_xhci, as the production model doesn't
have automatic switching capabilities. The ID pin was removed in favor
of the usb debug function which also doesn't work.
Add dr_mode = "host" to the same node, for the same reason.

Lets give it a few days if we can find a fix, if not we can revert

Please share the config and other details on what your running so that
Peter can repro this...

i already added the dr_mode=host to my xhci-node [1], but it is not pushed down to usb2-phy
it looks like the dr_mode property is ignored (or not yet set)...so the switch statement which is added by the patch choose the wrong initialization. in 5.18 init was done independ from phy-mode
# dmesg | grep -i debug
[ 1.093370] phy phy-fe8a0000.usb2phy.0: DEBUG: Passed rockchip_usb2phy_irq 981 port_id:1(OTG:0,HOST:1)

usb_host0_xhci: usb@fcc00000 {
phys = <&usb2phy0_otg>, <&combphy0 PHY_TYPE_USB3>; <<<< usb2phy0_otg seems to be initialized to otg mode and dr_mode is not applied when rockchip_usb2phy_irq is run
second controller works
usb_host1_xhci: usb@fd000000 {
phy-names = "usb2-phy", "usb3-phy";
in case that defconfig is the cause like peter guessed...i use same defconfig for 5.18 (working) and 5.19-rc (only lower port working)
