2022-04-21usb: dwc3: Try usb-role-switch first in dwc3_drd_initSven Peter1-6/+5
If the PHY controller node has a "port" dwc3 tries to find an extcon device even when "usb-role-switch" is present. This happens because dwc3_get_extcon() sees that "port" node and then calls extcon_find_edev_by_node() which will always return EPROBE_DEFER in that case. On the other hand, even if an extcon was present and dwc3_get_extcon() was successful it would still be ignored in favor of "usb-role-switch". Let's just first check if "usb-role-switch" is configured in the device tree and directly use it instead and only try to look for an extcon device otherwise.

2022-04-21usb: mtu3: fix USB 3.0 dual-role-switch from device to hostMacpaul Lin1-4/+2
Issue description: When an OTG port has been switched to device role and then switch back to host role again, the USB 3.0 Host (XHCI) will not be able to detect "plug in event of a connected USB 2.0/1.0 ((Highspeed and Fullspeed) devices until system reboot. Root cause and Solution: There is a condition checking flag "ssusb->otg_switch.is_u3_drd" in toggle_opstate(). At the end of role switch procedure, toggle_opstate() will be called to set DC_SESSION and SOFT_CONN bit. If "is_u3_drd" was set and switched the role to USB host 3.0, bit DC_SESSION and SOFT_CONN will be skipped hence caused the port cannot detect connected USB 2.0 (Highspeed and Fullspeed) devices. Simply remove the condition check to solve this issue.

2022-04-21usb: usbip: add missing device lock on tweak configuration cmdNiels Dossche1-0/+2
The function documentation of usb_set_configuration says that its callers should hold the device lock. This lock is held for all callsites except tweak_set_configuration_cmd. The code path can be executed for example when attaching a remote USB device. The solution is to surround the call by the device lock. This bug was found using my experimental own-developed static analysis tool, which reported the missing lock on v5.17.2. I manually verified this bug report by doing code review as well. I runtime checked that the required lock is not held. I compiled and runtime tested this on x86_64 with a USB mouse. After applying this patch, my analyser no longer reports this potential bug.

2022-04-21usb: dwc3: fix backwards compat with rockchip devicesPeter Geis1-0/+23
Commit 33fb697ec7e5 ("usb: dwc3: Get clocks individually") moved from the clk_bulk api to individual clocks, following the snps,dwc3.yaml dt-binding for clock names. Unfortunately the rk3328 (and upcoming rk356x support) use the rockchip,dwc3.yaml which has different clock names, which are common on devices using the glue layer. The rk3328 does not use a glue layer, but attaches directly to the dwc3 core driver. The offending patch series failed to account for this, thus dwc3 was broken on rk3328. To retain backwards compatibility with rk3328 device trees we must also check for the alternate clock names.

This wakeup signal will turn on when ehci runtime suspend, which will trigger a system control interrupt that will resume ehci back to D0. As no device connect, ehci will be set to runtime suspend and turn on the internal latched wakeup signal again. It will cause a suspend-resume loop and generate system control interrupt continuously.

There are few scenerio when PMC reports 'busy condition' and command fail. If PMC receives a high priority command while servicing a low priority command then it discards the low priority command and start servicing the high priority command. The lower priority command fail and driver returns error. If the same command resend to the PMC then PMC latches the command and service it accordingly. Thus adds the retry logic for the PMC command.

Before the following change was introduced: "43cd0023872e usb: gadget: uvc_video: add worker to handle the frame pumping", the pause flag status was discarded and never returned.

After mnt_hold_writers() has been called we will always have set MNT_WRITE_HOLD and consequently we always need to pair mnt_hold_writers() with mnt_unhold_writers(). After the recent cleanup in [1] where Al switched from a do-while to a for loop the cleanup currently fails to unset MNT_WRITE_HOLD for the first mount that was changed. Fix this and make sure that the first mount will be cleaned up and add some comments to make it more obvious.
