      usb: fixes for v4.4-rc2
      
      First round of fixes for this -rc cycle. We have the
      usual set of miscellaneous fixes. The important
      thing here is support for Intel Broxton SoC on dwc3,
      some fixes for Rockchip SoCs on dwc2 and a fix on
      dwc3 to let it report lower speeds than
      USB_SPEED_SUPER.

      usb: gadget: atmel_usba_udc: Expose correct device speed · d134c48d
      Douglas Gilbert authored
      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).

      usb: dwc3: gadget: let us set lower max_speed · b9e51b2b
      Ben McCauley authored
      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.

      usb: musb: fix tx fifo flush handling · 68fe05e2
      Bin Liu authored
      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.

      Peter Chen authored
      The current code tries to allocate memory with GFP_KERNEL at
      interrupt context, it would show below warning during the enumeration
      when I test it with chipidea hardware, change GFP flag as GFP_ATOMIC
      can fix this issue.

      usb: dwc2: host: Fix remote wakeup when not in DWC2_L2 · 1fb7f12d
      Douglas Anderson authored
      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.
      
      Fixes: 734643df ("usb: dwc2: host: add flag to reflect bus state")

      usb: dwc2: host: Fix ahbcfg for rk3066 · f1659303
      Douglas Anderson authored
      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.

      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.

      ARC: [arcompact] Handle bus error from userspace as Interrupt not exception · 541366da
      Vineet Gupta authored
      Bus errors from userspace on ARCompact based cores are handled by core
      as a high priority L2 interrupt but current code treated it as interrupt
      Handling an interrupt like exception is certainly not going to go unnoticed.
      (and it worked so far as we never saw a Bus error from userspace until
      IPPK guys tested a DDR controller with ECC error detection etc hence
      needed to explicitly trigger/handle such errors)
      
       - So move mem_service exception handler from common code into ARCv2 code.
       - In ARCompact code, define  mem_service as L2 interrupt handler which
         just drops down to pure kernel mode and goes of to enqueue SIGBUS

        changes to realize the improved simplicity, that now renders the
        original include/target/configfs_macros.h CPP magic for fabric drivers
        and others, unnecessary and obsolete.
      
        And with common code in place, new configfs attributes can be added

      an abstraction for System Trace Module devices").
      
      This merge resolution comes from Alexander Shishkin, who updated his stm
      class tracing abstraction to account for the removal of the old
      show_attribute and store_attribute methods in commit 51798222
      ("configfs: remove old API") from this pull.  As Alexander says about

       "There's no need to keep an extra wrapper structure per item and the
        awkward show_attribute/store_attribute item ops are no longer needed.
      
        This patch converts policy code to the new api, all the while making
