      usb: musb: make all glue layer export struct musb_platform_ops · 743411b3
      Felipe Balbi authored
      preparing to a big refactor on musb code. We need
      to be able to compile in all glue layers (or at
      least all ARM-based ones) together and have a
      working binary.
      
      While preparing for that, we move every glue
      layer to export only one symbol, which is
      a struct musb_platform_ops, and make all
      other functions static.
      
      Later patches will come to allow for compiling
      all glue layers together and have a working
      binary.

      usb: musb: introduce struct musb_platform_ops · 3ca8abb8
      Felipe Balbi authored
      This will be passed to musb_core by platform glue
      layer in order to make it easier to compile support
      for several HW glue layers.
      
      Later patches will come using this structure and
      also moving HW glue layers to its own platform
      driver; the idea is to be able to handle platform
      peculiarities in a manner which doesn't affect one
      another.

      This patch makes sure not to assign the_card if gaudio_open_snd_dev fails,
      since the parent function will deallocate the card.
      
      Also make sure all filp's in gaudio_open_snd_dev is assigned NULL upon error
      and gaudio_close_snd_dev only cleanups when the filp's are non-NULL.

      USB: improve uses of usb_mark_last_busy · c08512c7
      Alan Stern authored
      This patch (as1434) cleans up the uses of usb_mark_last_busy() in
      usbcore.  The function will be called when a device is resumed and
      whenever a usage count is decremented.  A call that was missing from
      the hub driver is added: A hub is used whenever one of its ports gets
      suspended (this prevents hubs from suspending immediately after their
      last child).
      
      In addition, the call to disable autosuspend support for new devices
      by default is moved from usb_detect_quirks() (where it doesn't really
      belong) into usb_new_device() along with all the other runtime-PM
      initializations.  Finally, an extra pm_runtime_get_noresume() is added
      to prevent new devices from autosuspending while they are being
      registered.

      USB: use the runtime-PM autosuspend implementation · fcc4a01e
      Alan Stern authored
      This patch (as1428) converts USB over to the new runtime-PM core
      autosuspend framework.  One slightly awkward aspect of the conversion
      is that USB devices will now have two suspend-delay attributes: the
      old power/autosuspend file and the new power/autosuspend_delay_ms
      file.  One expresses the delay time in seconds and the other in
      milliseconds, but otherwise they do the same thing.  The old attribute
      can be deprecated and then removed eventually.
