      ARM: dts: omap5: Add bus_dma_limit for L3 bus · dfa7ea30
      Roger Quadros authored
      The L3 interconnect's memory map is from 0x0 to
      0xffffffff. Out of this, System memory (SDRAM) can be
      accessed from 0x80000000 to 0xffffffff (2GB)
      
      OMAP5 does support 4GB of SDRAM but upper 2GB can only be
      accessed by the MPU subsystem.
      
      Add the dma-ranges property to reflect the physical address limit
      of the L3 bus.

      ARM: dts: omap4-droid4: Fix lost touchscreen interrupts · 4abd9930
      Tony Lindgren authored
      Looks like we can have the maxtouch touchscreen stop producing interrupts
      if an edge interrupt is lost. This can happen easily when the SoC idles as
      the gpio controller may not see any state for an edge interrupt if it
      is briefly triggered when the system is idle.
      
      Also it looks like maxtouch stops sending any further interrupts if the
      interrupt is not handled. And we do have several cases of maxtouch already
      configured with a level interrupt, so let's do that.
      
      With level interrupt the gpio controller has the interrupt state visible
      after idle. Note that eventually we will probably also be using the
      Linux generic wakeirq configured for the controller, but that cannot be
      done until the maxtouch driver supports runtime PM.

      Add the dma-ranges property to reflect the physical address limit
      of the L3 bus.
      
      Issues ere observed only with SATA on DRA7-EVM with 4GB RAM
      and CONFIG_ARM_LPAE enabled. This is because the controller
      supports 64-bit DMA and its driver sets the dma_mask to 64-bit
      thus resulting in DMA accesses beyond L3 limit of 2G.
      
      Setting the correct bus_dma_limit fixes the issue.

      soc: fsl: dpio: register dpio irq handlers after dpio create · fe8fe772
      Grigore Popescu authored
      The dpio irqs must be registered when you can actually
      receive interrupts, ie when the dpios are created.
      Kernel goes through NULL pointer dereference errors
      followed by kernel panic [1] because the dpio irqs are
      enabled before the dpio is created.

      Fix by updating the values to bootloader timings that have been tested
      to be working on Nokia N900 with OneNAND manufacturers: Samsung,

      Commit adb72394 ("ARM: OMAP2+: Drop legacy platform data for am3
      lcdc") dropped legacy platform data but we never added the quirks for
      SWSUP_SIDLE and SWSUP_MSTANDBY for lcdc for ti-sysc driver.
      
      This breaks suspend/resume. Let's fix the issue by enabling the same
      quirks for ti-sysc driver as we had earlier with platform data.

      Pull ARM SoC fixes from Olof Johansson:
       "We've been accruing these for a couple of weeks, so the batch is a bit
        bigger than usual.
      
        Largest delta is due to a led-bl driver that is added -- there was a
        miscommunication before the merge window and the driver didn't make it
        in. Due to this, the platforms needing it regressed. At this point, it
        seemed easier to add the new driver than unwind the changes.
      
        Besides that, there are a handful of various fixes:
      
         - AMD tee memory leak fix
      
         - A handful of fixlets for i.MX SCU communication
      
         - A few maintainers woke up and realized DEBUG_FS had been missing
           for a while, so a few updates of that.
      
        ... and the usual collection of smaller fixes to various platforms"

      io_uring: fix lockup with timeouts · f0e20b89
      Pavel Begunkov authored
      There is a recipe to deadlock the kernel: submit a timeout sqe with a
      linked_timeout (e.g.  test_single_link_timeout_ception() from liburing),
      and SIGKILL the process.
      
      Then, io_kill_timeouts() takes @ctx->completion_lock, but the timeout
      isn't flagged with REQ_F_COMP_LOCKED, and will try to double grab it
      during io_put_free() to cancel the linked timeout. Probably, the same
      can happen with another io_kill_timeout() call site, that is
      io_commit_cqring().
