When choose randconfig for kernel build, it reports below warning: "warning: (USB_OTG_FSM && FSL_USB2_OTG && USB_MV_OTG) selects USB_OTG which has unmet direct dependencies (USB_SUPPORT && USB && PM)" In fact, USB_OTG is visible symbol and depends on PM, so the driver needs to depend on it to reduce dependency problem.

Clear device initiated resume variables once device is fully up and running in U0 state. Resume needs to be signaled for 20ms for usb2 devices before they can be moved to U0 state. An interrupt is triggered if a device initiates resume. As we handle the event in interrupt context we can not sleep for 20ms, so we instead set a resume flag, a timestamp, and start the roothub polling. The roothub code will later move the port to U0 when it finds a port in resume state with the resume flag set, and timestamp passed by 20ms. A host initiated resume is however not done in interrupt context, and host initiated resume code will directly signal resume, wait 20ms and then move the port to U0. These two codepaths can race, if we are in the middle of a host initated resume, while sleeping for 20ms, we may handle a port event and find the port in resume state. The port event handling code will assume the resume was device initiated and set the resume flag and timestamp. Root hub code will however not catch the port in resume state again as the host initated resume code has already moved the port to U0. The resume flag and timestamp will remain set for this port preventing port from suspending again (LPM setting port to U3) Fix this for now by always clearing the device initated resume parameters once port is in U0 Cc: stable <stable@vger.kernel.org> Signed-off-by: NMathias Nyman <mathias.nyman@linux.intel.com> Signed-off-by: NGreg Kroah-Hartman <gregkh@linuxfoundation.org>

Function ep_ring_is_processing() checks the dequeue pointer in endpoint context to know whether an endpoint is busy with processing TRBs. This is not correct since dequeue pointer field in an endpoint context is only valid when the endpoint is in Halted or Stopped states. This buggy code causes audio noise when playing sound with USB headset connected to host controllers which support CFC (one of xhci 1.1 features). This patch should exist in stable kernel since v4.3.

Existing Intel xHCI controllers require a delay of 1 mS, after setting the CMD_RESET bit in command register, before accessing any HC registers. This allows the HC to complete the reset operation and be ready for HC register access. Without this delay, the subsequent HC register access, may result in a system hang, very rarely. Verified CherryView / Braswell platforms go through over 5000 warm reboot cycles (which was not possible without this patch), without any xHCI reset hang.

Following changes that appeared in lk 4.0.0, the gadget udc driver for some ARM based Atmel SoCs (e.g. at91sam9x5 and sama5d3 families) incorrectly deduced full-speed USB link speed even when the hardware had negotiated a high-speed link. The fix is to make sure that the UDPHS Interrupt Enable Register value does not mask the SPEED bit in the Interrupt Status Register. For a mass storage gadget this problem lead to failures when the host had a USB 3 port with the xhci_hcd driver. If the host was a USB 2 port using the ehci_hcd driver then the mass storage gadget worked (but probably at a lower speed than it should have).

In some SoCs, dwc3 is implemented as a USB2.0 only core, meaning that it can't ever achieve SuperSpeed. Currect driver always sets gadget.max_speed to USB_SPEED_SUPER unconditionally. This can causes issues to some Host stacks where the host will issue a GetBOS() request and we will reply with a BOS containing Superspeed Capability Descriptor. At least Windows seems to be upset by this fact and prints a warning that we should connect $this device to another port.

Here are a few changes in musb_h_tx_flush_fifo(). - It has been observed that sometimes (if not always) musb is unable to flush tx fifo during urb dequeue when disconnect a device. But it seems to be harmless, since the tx fifo flush is done again in musb_ep_program() when re-use the hw_ep. But the WARN() floods the console in the case when multiple tx urbs are queued, so change it to dev_WARN_ONCE(). - applications could queue up many tx urbs, then the 1ms delay could causes minutes of delay in device disconnect. So remove it to get better user experience. The 1ms delay does not help the flushing anyway. - cleanup the debug code - related to lastcsr. ---- Note: The tx fifo flush issue has been observed during device disconnect on AM335x. To reproduce the issue, ensure tx urb(s) are queued when unplug the usb device which is connected to AM335x usb host port. I found using a usb-ethernet device and running iperf (client on AM335x) has very high chance to trigger the problem. Better to turn on dev_dbg() in musb_cleanup_urb() with CPPI enabled to see the issue when aborting the tx channel. Signed-off-by: NBin Liu <b-liu@ti.com> Signed-off-by: NFelipe Balbi <balbi@ti.com>

In commit 734643df ("usb: dwc2: host: add flag to reflect bus state") we changed dwc2_port_suspend() not to set the lx_state anymore (instead it sets the new bus_suspended variable). This introduced a bug where we would fail to detect device insertions if: 1. Plug empty hub into dwc2 2. Plug USB flash drive into the empty hub. 3. Wait a few seconds 4. Unplug USB flash drive 5. Less than 2 seconds after step 4, plug the USB flash drive in again. The dwc2_hcd_rem_wakeup() function should have been changed to look at the new bus_suspended variable. Let's fix it. Since commit b46146d5 ("usb: dwc2: host: resume root hub on remote wakeup") talks about needing the root hub resumed if the bus was suspended, we'll include it in our test. It appears that the "port_l1_change" should only be set to 1 if we were in DWC2_L1 (the driver currently never sets this), so we'll update the former "else" case based on this test.

The comment for ahbcfg for rk3066 parameters (also used for rk3288) claimed that ahbcfg was INCR16, but it wasn't. Since the bits weren't shifted properly, the 0x7 ended up being masked and we ended up programming 0x3 for the HBstLen. Let's set it to INCR16 properly. As per Wu Liang Feng at Rockchip this may increase transmission efficiency. I did blackbox tests with writing 0s to a USB-based SD reader (forcefully capping CPU Freq to try to measure efficiency): cd /sys/devices/system/cpu/cpu0/cpufreq echo userspace > scaling_governor echo 126000 > scaling_setspeed for i in $(seq 10); do dd if=/dev/zero of=/dev/sdb bs=1M count=750 done With the above tests I found that speeds went from ~15MB/s to ~18MB/s. Note that most other tests I did (including reading from the same USB reader) didn't show any difference in performance.

The DEVICE_HWI type was added under the faulty assumption that Huawei devices based on Qualcomm chipsets and firmware use the static USB interface numbering known from Gobi devices. But this model does not apply to Huawei devices like the HP branded lt4112 (Huawei me906e). Huawei firmwares will dynamically assign interface numbers. Functions are renumbered when the firmware is reconfigured. Fix by changing the DEVICE_HWI type to use a simplified version of Huawei's subclass + protocol scheme: Blacklisting known network interface combinations and assuming the rest are serial.

There is a bit of a mess in the order of arguments to the ulpi write callback. There is int ulpi_write(struct ulpi *ulpi, u8 addr, u8 val) in drivers/usb/common/ulpi.c; struct usb_phy_io_ops { ... int (*write)(struct usb_phy *x, u32 val, u32 reg); } in include/linux/usb/phy.h. The callback registered by the musb driver has to comply to the latter, but up to now had "offset" first which effectively made the function broken for correct users. So flip the order and while at it also switch to the parameter names of struct usb_phy_io_ops's write.

cpu_relax() on ARC has been barrier only for SMP (and no-op for UP). Per recent discussions, it is safer to make it a compiler barrier unconditionally.
