      ARM: OMAP1: OHCI: use platform_data fn ptr to enable OCPI bus · d3645d39
      Paul Walmsley 提交于
      The OMAP1 OHCI driver needs to enable the OCPI IP block before it can
      work.  Previously, the driver was simply calling a symbol defined in
      the OMAP platform code, but this is incorrect: drivers should be fully
      decoupled from platform and architecture code.
      
      So instead, modify the driver to call through a platform_data function
      pointer instead.  We skip any DT aspect, since OMAP1 is not scheduled
      to be converted to DT in the near future.
      
      This resolves the following sparse warning:
      
      It also gets rid of a cpu_is_omap16xx() call in a driver.
      
      In the long term, it probably makes sense to move the OCPI bus code to
      somewhere under drivers/.  This should avoid the whole platform_data/DT
      issue with this function.

      omap: headers: Move remaining headers from include/mach to include/plat · ce491cf8

      Move the remaining headers under plat-omap/include/mach

      USB: automatically enable RHSC interrupts · b5fb454f
      Alan Stern 提交于
      This patch (as1069c) changes the way OHCI root-hub status-change
      interrupts are enabled.  Currently a special HCD method,
      hub_irq_enable(), is called when the hub driver is finished using a
      root hub.  This approach turns out to be subject to races, resulting
      in unnecessary polling.
      
      The patch does away with the method entirely.  Instead, the driver
      automatically enables the RHSC interrupt when no more status changes
      are present.  This scheme is safe with controllers using
      level-triggered semantics for their interrupt flags.

      USB: OHCI: host-controller resumes leave root hub suspended · 43bbb7e0
      Alan Stern 提交于
      Drivers in the ohci-hcd family should perform certain tasks whenever
      their controller device is resumed.  These include checking for loss
      of power during suspend, turning on port power, and enabling interrupt
      requests.
      
      Until now these jobs have been carried out when the root hub is
      resumed, not when the controller is.  Many drivers work around the
      resulting awkwardness by automatically resuming their root hub
      whenever the controller is resumed.  But this is wasteful and
      unnecessary.
      
      To simplify the situation, this patch (as1066) adds a new core
      routine, ohci_finish_controller_resume(), which can be used by all the
      OHCI-variant drivers.  They can call the new routine instead of
      resuming their root hubs.  And ohci-pci.c can call it instead of using
      its own special-purpose handler.

      USB: Properly unregister reboot notifier in case of failure in ehci hcd · 64a21d02
      Aleksey Gorelov 提交于
      If some problem occurs during ehci startup, for instance, request_irq fails,
      echi hcd driver tries it best to cleanup, but fails to unregister reboot
      notifier, which in turn leads to crash on reboot/poweroff.
      
      The following patch resolves this problem by not using reboot notifiers
      anymore, but instead making ehci/ohci driver get its own shutdown method.  For
      PCI, it is done through pci glue, for everything else through platform driver
      glue.
      
      One downside: sa1111 does not use platform driver stuff, and does not have its
      own shutdown hook, so no 'shutdown' is called for it now.  I'm not sure if it
      is really necessary on that platform, though.

      USB: OHCI avoids root hub timer polling · d413984a
      David Brownell 提交于
      This teaches OHCI to use the root hub status change (RHSC) IRQ, bypassing
      root hub timers most of the time and switching over to the "new" root hub
      polling scheme.  It's complicated by the fact that implementations of OHCI
      trigger and ack that IRQ differently (the spec is vague there).
      
      Avoiding root hub timers helps mechanisms like "dynamic tick" leave the
      CPU in lowpower modes for longer intervals.

      [PATCH] fix missing includes · 4e57b681
      Tim Schmielau 提交于
      I recently picked up my older work to remove unnecessary #includes of
      sched.h, starting from a patch by Dave Jones to not include sched.h
      from module.h. This reduces the number of indirect includes of sched.h
      by ~300. Another ~400 pointless direct includes can be removed after
      this disentangling (patch to follow later).
      However, quite a few indirect includes need to be fixed up for this.
      
      In order to feed the patches through -mm with as little disturbance as
      possible, I've split out the fixes I accumulated up to now (complete for
      i386 and x86_64, more archs to follow later) and post them before the real
      patch.  This way this large part of the patch is kept simple with only
      adding #includes, and all hunks are independent of each other.  So if any
      hunk rejects or gets in the way of other patches, just drop it.  My scripts
      will pick it up again in the next round.
