      USB-PD tcpm: bad warning+size, PPS adapters · c215e48e
      Douglas Gilbert authored
      Augmented Power Delivery Objects (A)PDO_s are used by USB-C
      PD power adapters to advertize the voltages and currents
      they support. There can be up to 7 PDO_s but before PPS
      (programmable power supply) there were seldom more than 4
      or 5. Recently Samsung released an optional PPS 45 Watt power
      adapter (EP-TA485) that has 7 PDO_s. It is for the Galaxy 10+
      tablet and charges it quicker than the adapter supplied at
      purchase. The EP-TA485 causes an overzealous WARN_ON to soil
      the log plus it miscalculates the number of bytes to read.
      
      So this bug has been there for some time but goes
      undetected for the majority of USB-C PD power adapters on
      the market today that have 6 or less PDO_s. That may soon
      change as more USB-C PD adapters with PPS come to market.
      
      Tested on a EP-TA485 and an older Lenovo PN: SA10M13950
      USB-C 65 Watt adapter (without PPS and has 4 PDO_s) plus
      several other PD power adapters.

      USB-serial fixes for 5.5-rc5
      
      Here's a couple of new modem device ids, including a new quirk for
      devices that expect zero-length packets.
      
      Due to the holidays, only the first one has been in linux-next and with
      no reported issues.

      phy/rockchip: inno-hdmi: round clock rate down to closest 1000 Hz · 4f510aa1
      Jonas Karlman authored
      Commit 287422a9 ("drm/rockchip: Round up _before_ giving to the clock framework")
      changed what rate clk_round_rate() is called with, an additional 999 Hz
      added to the requsted mode clock. This has caused a regression on RK3328
      and presumably also on RK3228 because the inno-hdmi-phy clock requires an
      exact match of the requested rate in the pre pll config table.
      
      When an exact match is not found the parent clock rate (24MHz) is returned
      to the clk_round_rate() caller. This cause wrong pixel clock to be used and
      result in no-signal when configuring a mode on RK3328.
      
      Fix this by rounding the rate down to closest 1000 Hz in round_rate func,
      this allows an exact match to be found in pre pll config table.

      usb: chipidea: host: Disable port power only if previously enabled · c1ffba30
      Guenter Roeck authored
      On shutdown, ehci_power_off() is called unconditionally to power off
      each port, even if it was never called to power on the port.
      For chipidea, this results in a call to ehci_ci_portpower() with a request
      to power off ports even if the port was never powered on.
      This results in the following warning from the regulator code.

      usb: cdns3: should not use the same dev_id for shared interrupt handler · af58e1fc
      Peter Chen authored
      Both drd and gadget interrupt handler use the struct cdns3 pointer as
      dev_id, it causes devm_free_irq at cdns3_gadget_exit doesn't free
      gadget's interrupt handler, it freed drd's handler. So, when the
      host interrupt occurs, the gadget's interrupt hanlder is still
      called, and causes below oops. To fix it, we use gadget's private
      data priv_dev as interrupt dev_id for gadget.

      USB: core: fix check for duplicate endpoints · 3e4f8e21
      Johan Hovold authored
      Amend the endpoint-descriptor sanity checks to detect all duplicate
      endpoint addresses in a configuration.
      
      Commit 0a8fd134 ("USB: fix problems with duplicate endpoint
      addresses") added a check for duplicate endpoint addresses within a
      single alternate setting, but did not look for duplicate addresses in
      other interfaces.
      
      The current check would also not detect all duplicate addresses when one
      endpoint is as a (bi-directional) control endpoint.
      
      This specifically avoids overwriting the endpoint entries in struct
      usb_device when enabling a duplicate endpoint, something which could
      potentially lead to crashes or leaks, for example, when endpoints are
      later disabled.

      phy: cpcap-usb: Improve host vs docked mode detection · 9492535e
      Tony Lindgren authored
      When docked to a Motorola lapdock or media dock, we're in USB A-host mode
      with VBUS provided by the dock. When in regular USB A-host mode, we're
      providing the VBUS. And in regular USB A-host mode we must also keep
      kicking the VBUS to keep it active.
      
      Let's wait a bit before configuring the USB PHY to allow some time between
      the ID and VBUS changes. And let's add vbus_provider flag so we can detect
      docked mode and regularo USB A-host mode better.
      
      With better USB A-host mode detection, we can now also just kick the
      VBUS to keep it enabled and leave out the unnecessary line muxing.
      
      We only need to set and clear vbus_provider in the delayed work so no
      locking is needed for it currently.

      phy: cpcap-usb: Prevent USB line glitches from waking up modem · 63078b6b
      Tony Lindgren authored
      The micro-USB connector on Motorola Mapphone devices can be muxed between
      the SoC and the mdm6600 modem. But even when used for the SoC, configuring
      the PHY with ID pin grounded will wake up the modem from idle state. Looks
      like the issue is probably caused by line glitches.
      
      We can prevent the glitches by using a previously unknown mode of the
      GPIO mux to prevent the USB lines from being connected to the moden while
      configuring the USB PHY, and enable the USB lines after configuring the
      PHY.
      
      Note that this only prevents waking up mdm6600 as regular USB A-host mode,
      and does not help when connected to a lapdock. The lapdock specific issue
      still needs to be debugged separately.

      Tony Lindgren authored
      Only the used bits get cleared with bitmap_zero() when we call
      gpiod_get_array_value_cansleep(). We must mask only the bits we're
      using for ddata->status as the other bits in the bitmap may not be
      initialized.
      
      And let's also drop useless debug code accidentally left over while
      at it.

      phy: cpcap-usb: Fix flakey host idling and enumerating of devices · 049226b9
      Tony Lindgren authored
      We must let the USB host idle things properly before we switch to debug
      UART mode. Otherwise the USB host may never idle after disconnecting
      devices, and that causes the next enumeration to be flakey.

      pipe: fix empty pipe check in pipe_write() · 0dd1e377
      Jan Stancek authored
      LTP pipeio_1 test is hanging with v5.5-rc2-385-gb8e382a1,
      with read side observing empty pipe and sleeping and write
      side running out of space and then sleeping as well. In this
      scenario there are 5 writers and 1 reader.
      
      Problem is that after pipe_write() reacquires pipe lock, it
      re-checks for empty pipe with potentially stale 'head' and
      doesn't wake up read side anymore. pipe->tail can advance
      beyond 'head', because there are multiple writers.
      
      Use pipe->head for empty pipe check after reacquiring lock
      to observe current state.
      
      Testing: With patch, LTP pipeio_1 ran successfully in loop for 1 hour.
               Without patch it hanged within a minute.
