2017-10-19usb: hub: Allow reset retry for USB2 devices on connect bounceMathias Nyman1-4/+7
If the connect status change is set during reset signaling, but the status remains connected just retry port reset. This solves an issue with connecting a 90W HP Thunderbolt 3 dock with a Lenovo Carbon x1 (5th generation) which causes a 30min loop of a high speed device being re-discovererd before usb ports starts working. [...] [ 389.023845] usb 3-1: new high-speed USB device number 55 using xhci_hcd [ 389.491841] usb 3-1: new high-speed USB device number 56 using xhci_hcd [ 389.959928] usb 3-1: new high-speed USB device number 57 using xhci_hcd [...] This is caused by a high speed device that doesn't successfully go to the enabled state after the second port reset. Instead the connection bounces (connected, with connect status change), bailing out completely from enumeration just to restart from scratch.

2017-10-19usb: dwc2: disable erroneous overcurrent conditionDinh Nguyen3-0/+12
For the case where an external VBUS is used, we should enable the external VBUS comparator in the driver. This would prevent an unnecessary overcurrent error which would then disable the host port. This patch uses the standard 'disable-over-current' binding to allow of the option of disabling the over-current condition.

2017-10-19usb: mtu3: set otg_sel for u2port only if works as dual-role modeChunfeng Yun1-2/+7
When set otg_sel(SSUSB_U2_PORT_OTG_SEL) for u2port which supports dual-role mode, the controller will automatically switch mode between host and device according to IDDIG signal. But if the u2port only supports device mode, and no IDDIG pin is provided, setting otg_sel may cause failure of detection by host. So set it only for dual-role mode.

Calls to regmap_read may fail with an -EINVAL return without setting usbc_irq1 and usbc_irq2. The error handling clean up expects these to have been set (or zero on a failure) and currently may try to clear the wrong IRQs if the uninitalized garbage values in usbc_irq1 or usbc_irq2 are non-zero.

2017-10-17usb: musb: Check for host-mode using is_host_active() on reset interruptJonathan Liu1-4/+2
The sunxi musb has a bug where sometimes it will generate a babble error on device disconnect instead of a disconnect IRQ. When this happens the musb controller switches from host mode to device mode (it clears MUSB_DEVCTL_HM/MUSB_DEVCTL_SESSION and sets MUSB_DEVCTL_BDEVICE) and gets stuck in this state. The babble error is misdetected as a bus reset because MUSB_DEVCTL_HM was cleared. To fix this, use is_host_active() rather than (devctl & MUSB_DEVCTL_HM) to detect babble error so that sunxi musb babble recovery can handle it by restoring the mode. This information is provided by the driver logic and does not rely on register contents.
