2021-01-18USB: serial: cp210x: set IXOFF thresholdsJohan Hovold1-0/+3
At least CP2102 requires the XON/XOFF limits to be initialised in order for software input flow control (IXOFF) to work. Specifically, XOFF is never sent if the XOFF limit is left at its default value of zero. Set the limits so that input is throttled when the FIFO free level drops below 128 bytes and restarted when the FIFO fill level drops below 128 bytes. Note that the threshold values have been chosen so that they can be used also with CP2105 which has the smallest FIFO of the currently supported device types (288 byte for the SCI port). If needed the limits can be made device specific later. Reviewed-by: Greg Kroah-Hartman <[email protected]> Signed-off-by: Johan Hovold <[email protected]>
2021-01-18USB: serial: cp210x: add support for software flow controlWang Sheng Long1-2/+65
When data is transmitted between two serial ports, the phenomenon of data loss often occurs. The two kinds of flow control commonly used in serial communication are hardware flow control and software flow control. In serial communication, If you only use RX/TX/GND Pins, you can't do hardware flow. So we often used software flow control and prevent data loss. The user sets the software flow control through the application program, and the application program sets the software flow control mode for the serial port chip through the driver. For the cp210 serial port chip, its driver lacks the software flow control setting code, so the user cannot set the software flow control function through the application program. This adds the missing software flow control.

2021-01-15xhci: make sure TRB is fully written before giving it to the controllerMathias Nyman1-0/+2
Once the command ring doorbell is rung the xHC controller will parse all command TRBs on the command ring that have the cycle bit set properly. If the driver just started writing the next command TRB to the ring when hardware finished the previous TRB, then HW might fetch an incomplete TRB as long as its cycle bit set correctly. A command TRB is 16 bytes (128 bits) long. Driver writes the command TRB in four 32 bit chunks, with the chunk containing the cycle bit last. This does however not guarantee that chunks actually get written in that order. This was detected in stress testing when canceling URBs with several connected USB devices. Two consecutive "Set TR Dequeue pointer" commands got queued right after each other, and the second one was only partially written when the controller parsed it, causing the dequeue pointer to be set to bogus values. This was seen as error messages: "Mismatch between completed Set TR Deq Ptr command & xHCI internal state" Solution is to add a write memory barrier before writing the cycle bit.

2021-01-15usb: gadget: u_ether: support configuring interface names.Lorenzo Colitti3-2/+58
This patch allows the administrator to configure the interface name of a function using u_ether (e.g., eem, ncm, rndis). Currently, all such interfaces, regardless of function type, are always called usb0, usb1, etc. This makes it very cumbersome to use more than one such type at a time, because userspace cannnot easily tell the interfaces apart and apply the right configuration to each one. Interface renaming in userspace based on driver doesn't help, because the interfaces all have the same driver. Without this patch, doing this require hacks/workarounds such as setting fixed MAC addresses on the functions, and then renaming by MAC address, or scraping configfs after each interface is created to find out what it is. Setting the interface name is done by writing to the same "ifname" configfs attribute that reports the interface name after the function is bound. The write must contain an interface pattern such as "usb%d" (which will cause the net core to pick the next available interface name starting with "usb"). This patch does not allow writing an exact interface name (as opposed to a pattern) because if the interface already exists at bind time, the bind will fail and the whole gadget will fail to activate. This could be allowed in a future patch. For compatibility with current userspace, when reading an ifname that has not currently been set, the result is still "(unnamed net_device)". Once a write to ifname happens, then reading ifname will return whatever was last written. Tested by configuring an rndis function and an ncm function on the same gadget, and writing "rndis%d" to ifname on the rndis function and "ncm%d" to ifname on the ncm function. When the gadget was bound, the rndis interface was rndis0 and the ncm interface was ncm0.

2021-01-15usb: dwc3: pci: ID for Tiger Lake CPUHeikki Krogerus1-0/+4
Tiger Lake SOC (the versions of it that have integrated USB4 controller) may have two DWC3 controllers. One is part of the PCH (Platform Controller Hub, i.e. the chipset) as usual, and the other is inside the actual CPU block. On all Intel platforms that have the two separate DWC3 controllers, the one inside the CPU handles USB3 and only USB3 traffic, while the PCH version handles USB2 and USB2 alone. The reason for splitting the two busses like this is to allow easy USB3 tunneling over USB4 connections. As USB2 is not tunneled over USB4, it has dedicated USB controllers (both xHCI and DWC3).

2021-01-14USB: gadget: dummy-hcd: Fix errors in port-reset handlingAlan Stern1-3/+7
Commit c318840fb2a4 ("USB: Gadget: dummy-hcd: Fix shift-out-of-bounds bug") messed up the way dummy-hcd handles requests to turn on the RESET port feature (I didn't notice that the original switch case ended with a fallthrough). The call to set_link_state() was inadvertently removed, as was the code to set the USB_PORT_STAT_RESET flag when the speed is USB2. In addition, the original code never checked whether the port was connected before handling the port-reset request. There was a check for the port being powered, but it was removed by that commit! In practice this doesn't matter much because the kernel doesn't try to reset disconnected ports, but it's still bad form. This patch fixes these problems by changing the fallthrough to break, adding back in the missing set_link_state() call, setting the port-reset status flag, adding a port-is-connected test, and removing a redundant assignment statement.

Descriptor list operation (bit2) : 0 disable reset, 1: enable reset Single mode operation (bit0) : 0 : disable, 1: enable Fixes: 7ecca2a4080c ("usb/gadget: Add driver for Aspeed SoC virtual hub") Cc: stable <[email protected]> Acked-by: Felipe Balbi <[email protected]> Acked-by: Joel Stanley <[email protected]> Signed-off-by: Ryan Chen <[email protected]> Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Greg Kroah-Hartman <[email protected]>
2021-01-12USB: ehci: fix an interrupt calltrace errorLongfang Liu1-0/+3
The system that use Synopsys USB host controllers goes to suspend when using USB audio player. This causes the USB host controller continuous send interrupt signal to system, When the number of interrupts exceeds 100000, the system will forcibly close the interrupts and output a calltrace error. When the system goes to suspend, the last interrupt is reported to the driver. At this time, the system has set the state to suspend. This causes the last interrupt to not be processed by the system and not clear the interrupt flag. This uncleared interrupt flag constantly triggers new interrupt event. This causing the driver to receive more than 100,000 interrupts, which causes the system to forcibly close the interrupt report and report the calltrace error. so, when the driver goes to sleep and changes the system state to suspend, the interrupt flag needs to be cleared.

2021-01-12ehci: fix EHCI host controller initialization sequenceEugene Korenevsky1-0/+12
According to EHCI spec, EHCI HC clears USBSTS.HCHalted whenever USBCMD.RS=1. However, it is a good practice to wait some time after setting USBCMD.RS (approximately 100ms) until USBSTS.HCHalted become zero. Without this waiting, VirtualBox's EHCI virtual HC accidentally hangs (see BugLink).

2021-01-12usb: typec: ucsi: Add support for USB role switchMayank Rana2-3/+55
UCSI already conveys the information about a port's connection status, whether it is operating in UFP or DFP mode, and whether the partner supports USB data or not. This information can be used to notify a dual-role controller to start up its host or peripheral mode accordingly. Add optional support for this by querying each port's fwnode to look for an associated USB role switch device. If present, call usb_role_switch_set() with the determined data role upon Connect Change or Connector Partner Change updates.

2021-01-12usb: dwc2: disable Link Power Management on STM32MP15 HS OTGAmelie Delaunay1-0/+4
Link Power Management (LPM) on STM32MP15 OTG HS encounters instabilities with some Host controllers. OTG core fails to exit L1 state in 200us: "dwc2 49000000.usb-otg: Failed to exit L1 sleep state in 200us." Then the device is still not enumerated. To avoid this issue, disable Link Power Management on STM32MP15 HS OTG.

When the core is in FS host mode, using the FS transceiver, and a Low-Speed device is connected, transceiver clock is 6Mhz. So, to support Low-Speed devices, enable support of FS/LS Low Power mode, so that the PHY supplies a 6 MHz clock during Low-Speed mode.

STM32MP15 ahbcfg register default value sets Burst length/type (HBSTLEN) to Single (32-bit accesses on AHB), which is not recommended, according to STM32MP157 Reference manual [1]. This patch sets Burst length/type (HBSTLEN) so that bus transactions target 16x32 bit accesses. This improves OTG controller performance.
