      crypto: ccp - Assign DMA commands to the channel's CCP · 7c468447
      Gary R Hook authored
      The CCP driver generally uses a round-robin approach when
      assigning operations to available CCPs. For the DMA engine,
      however, the DMA mappings of the SGs are associated with a
      specific CCP. When an IOMMU is enabled, the IOMMU is
      programmed based on this specific device.
      If the DMA operations are not performed by that specific
      CCP then addressing errors and I/O page faults will occur.
      Update the CCP driver to allow a specific CCP device to be
      requested for an operation and use this in the DMA engine

      Interrupt handling routine was calling req->base.complete() under
      spinlock.  In most cases this wasn't fatal but when combined with some
      of the cipher modes (like LRW) this caused recursion - starting the new
      encryption (s5p_aes_crypt()) while still holding the spinlock from
      previous round (s5p_aes_complete()).
      Beside that, the s5p_aes_interrupt() error handling path could execute
      two completions in case of error for RX and TX blocks.
      Rewrite the interrupt handling routine and the completion by:
      1. Splitting the operations on scatterlist copies from
         s5p_aes_complete() into separate s5p_sg_done(). This still should be
         done under lock.
         The s5p_aes_complete() now only calls req->base.complete() and it has
         to be called outside of lock.
      2. Moving the s5p_aes_complete() out of spinlock critical sections.
         In interrupt service routine s5p_aes_interrupts(), it appeared in few
         places, including error paths inside other functions called from ISR.
         This code was not so obvious to read so simplify it by putting the
         s5p_aes_complete() only within ISR level.

        This includes two branches for arm64 dt updates, both following up on
        earlier changes for the same platforms that are already merged:
         - add USB3 support in Exynos7
         - minor PM related updates
         - new machines: WeTek Set-top-boxes
         - various devices added to DT
        There are also a couple of bugfixes that trickled in since the start
        of the merge window:
         - The moxart_defconfig was not building the intended platform
         - CPU-hotplug was broken on ux500
         - Coresight was broken on Juno (never worked)"
