      USB: ohci-exynos: Remove non-DT support · c00809d3
      Jingoo Han authored
      The non-DT for EXYNOS SoCs is not supported from v3.11.
      Thus, there is no need to support non-DT for Exynos OHCI driver.
      
      The 'include/linux/platform_data/usb-ohci-exynos.h' file has been
      used for non-DT support. Thus, the 'usb-ohci-exynos.h' file can
      be removed.

      usb/hcd: remove unnecessary local_irq_save · 88ed9fd5
      Michael Opdenacker authored
      Remove the use of local_irq_save() and IRQF_DISABLED, no longer needed since
      interrupt handlers are always run with interrupts disabled on the
      current CPU.
      
      Tested successfully with 3.12.0-rc4 on my PC. Didn't find
      any issue because of this change.

      USB: EHCI: start new isochronous streams ASAP · a393a807
      Alan Stern authored
      This patch changes the initial delay before the startup of a newly
      scheduled isochronous stream.  Currently the stream doesn't start
      for at least 5 ms (40 microframes).  This value is just an estimate;
      it has no real justification.
      
      Instead, we can start the stream as soon as possible after the
      scheduling computations are complete.  Essentially this requires
      nothing more than reading the frame counter after the stream is
      scheduled, instead of before.

      USB: EHCI: create per-TT bandwidth tables · b35c5009
      Alan Stern authored
      This patch continues the scheduling changes in ehci-hcd by adding a
      table to store the bandwidth allocation below each TT.  This will
      speed up the scheduling code, as it will no longer need to read
      through the entire schedule to compute the bandwidth currently in use.
      
      Properly speaking, the FS/LS budget calculations should be done in
      terms of full-speed bytes per microframe, as described in the USB-2
      spec.  However the driver currently uses microseconds per microframe,
      and the scheduling code isn't robust enough at this point to change
      over.  For the time being, we leave the calculations as they are.

      Manjunath is no longer at Linaro, the email address bounces.  Given
      that, and the fact that others have reported problems with these
      patches, I'm reverting them until someone from Linaro who can SUPPORT
      THEM submits them.
      
      I will no longer accept patches from linaro.com developers unless a
      senior Linaro developer has signed off on them, which did not happen
      with this patch set.
