      kernel/sys.c: Clarify that UNAME26 does not generate unique versions anymore · b7285b42
      Jonathan Neuschäfer authored
      UNAME26 is a mechanism to report Linux's version as 2.6.x, for
      compatibility with old/broken software.  Due to the way it is
      implemented, it would have to be updated after 5.0, to keep the
      resulting versions unique.  Linus Torvalds argued:
      
       "Do we actually need this?
      
        I'd rather let it bitrot, and just let it return random versions. It
        will just start again at 2.4.60, won't it?
      
        Anybody who uses UNAME26 for a 5.x kernel might as well think it's
        still 4.x. The user space is so old that it can't possibly care about
        differences between 4.x and 5.x, can it?
      
        The only thing that matters is that it shows "2.4.<largeenough>",
        which it will do regardless"

      Pull ARM SoC fixes from Olof Johansson:
       "A bigger batch than I anticipated this week, for two reasons:
      
         - Some fallout on Davinci from board file -> DTB conversion, that
           also includes a few longer-standing fixes (i.e. not recent
           regressions).
      
         - drivers/reset material that has been in linux-next for a while, but
           didn't get sent to us until now for a variety of reasons
           (maintainer out sick, holidays, etc). There's a functional
           dependency in there such that one platform (Altera's SoCFPGA) won't
           boot without one of the patches; instead of reverting the patch
           that got merged, I looked at this set and decided it was small
           enough that I'll pick it up anyway. If you disagree I can revisit
           with a smaller set.
      
        That being said, there's also a handful of the usual stuff:
      
         - Fix for a crash on Armada 7K/8K when the kernel touches
           PSCI-reserved memory
      
         - Fix for PCIe reset on Macchiatobin (Armada 8K development board,
           what this email is sent from in fact :)
      
         - Enable a few new-merged modules for Amlogic in arm64 defconfig
      
         - Error path fixes on Integrator
      
         - Build fix for Renesas and Qualcomm
      
         - Initialization fix for Renesas RZ/G2E
      
        .. plus a few more fixlets"

      Pull driver core fixes from Greg KH:
       "Here is one small sysfs change, and a documentation update for 5.0-rc2
      
        The sysfs change moves from using BUG_ON to WARN_ON, as discussed in
        an email thread on lkml while trying to track down another driver bug.
        sysfs should not be crashing and preventing people from seeing where
        they went wrong. Now it properly recovers and warns the developer.
      
        The documentation update removes the use of BUS_ATTR() as the kernel
        is moving away from this to use the specific BUS_ATTR_RW() and friends
        instead. There are pending patches in all of the different subsystems
        to remove the last users of this macro, but for now, don't advertise
        it should be used anymore to keep new ones from being introduced.

      phy: fix build breakage: add PHY_MODE_SATA · e1706720
      John Hubbard authored
      Commit 49e54187 ("ata: libahci_platform: comply to PHY framework") uses
      the PHY_MODE_SATA, but that enum had not yet been added. This caused a
      build failure for me, with today's linux.git.
      
      Also, there is a potentially conflicting (mis-named) PHY_MODE_SATA, hiding
      in the Marvell Berlin SATA PHY driver.
      
      Fix the build by:
      
          1) Renaming Marvell's defined value to a more scoped name,
             in order to avoid any potential conflicts: PHY_BERLIN_MODE_SATA.
      
          2) Adding the missing enum, which was going to be added anyway as part
             of [1].

      Pull dma_zalloc_coherent() removal from Christoph Hellwig:
       "We've always had a weird situation around dma_zalloc_coherent. To
        safely support mapping the allocations to userspace major
        architectures like x86 and arm have always zeroed allocations from
        dma_alloc_coherent, but a couple other architectures were missing that
        zeroing either always or in corner cases.
      
        Then later we grew anothe dma_zalloc_coherent interface to explicitly
        request zeroing, but that just added __GFP_ZERO to the allocation
        flags, which for some allocators that didn't end up using the page
        allocator ended up being a no-op and still not zeroing the
        allocations.
      
        So for this merge window I fixed up all remaining architectures to
        zero the memory in dma_alloc_coherent, and made dma_zalloc_coherent a
        no-op wrapper around dma_alloc_coherent, which fixes all of the above
        issues.
      
        dma_zalloc_coherent is now pointless and can go away, and Luis helped
        me writing a cocchinelle script and patch series to kill it, which I
        think we should apply now just after -rc1 to finally settle these
        issue"

      ata: ahci: mvebu: request PHY suspend/resume for Armada 3700 · bde0b5c1
      Miquel Raynal authored
      A feature has been added in the libahci driver: the possibility to set
      a new flag in hpriv->flags to let the core handle PHY suspend/resume
      automatically. Make use of this feature to make suspend to RAM work
      with SATA drives on A3700.

      ata: ahci: mvebu: add Armada 3700 initialization needed for S2RAM · 2f558bc3
      Miquel Raynal authored
      A3700 comphy initialization is done in the firmware (TF-A). Looking at
      the SATA PHY initialization routine, there is a comment about "vendor
      specific" registers. Two registers are mentioned. They are not
      initialized there in the firmware because they are AHCI related, while
      the firmware at this location does only PHY configuration. The
      solution to avoid doing such initialization is relying on U-Boot.
      
      While this work at boot time, U-Boot is definitely not going to run
      during a resume after suspending to RAM.
      
      Two possible solutions were considered:
      * Fixing the firmware.
      * Fixing the kernel driver.
      
      The first solution would take ages to propagate, while the second
      solution is easy to implement as the driver as been a little bit
      reworked to prepare for such platform configuration. Hence, this patch
      adds an Armada 3700 configuration function to set these two registers
      both at boot time (in the probe) and after a suspend (in the resume
      path).

      ata: ahci: mvebu: do Armada 38x configuration only on relevant SoCs · 96dbcb40
      Miquel Raynal authored
      At the beginning, only Armada 38x SoCs where supported by the
      ahci_mvebu.c driver. Commit 15d3ce7b ("ata: ahci_mvebu: add
      support for Armada 3700 variant") introduced Armada 3700 support. As
      opposed to Armada 38x SoCs, the 3700 variants do not have to configure
      mbus and the regret option. This patch took care of avoiding such
      configuration when not needed in the probe function, but failed to do
      the same in the resume path. While doing so looks harmless by
      experience, let's clean the driver logic and avoid doing this useless
      configuration with Armada 3700 SoCs.
      
      Because the logic is very similar between these two places, it has
      been decided to factorize this code and put it in a "Armada 38x
      configuration function". This function is part of a new
      (per-compatible) platform data structure, so that the addition of such
      configuration function for Armada 3700 will be eased.

      For Armada 64-bit SoCs, like the A3700 also using this AHCI driver, PM
      platform support has always existed.
      
      There are even suspend/resume hooks in this driver since:
      commit d6ecf158 ("ata: ahci_mvebu: add suspend/resume support")
      
      Remove the stale comment at the end of this driver stating that all

      ata: libahci_platform: comply to PHY framework · 49e54187
      Miquel Raynal authored
      Current implementation of the libahci does not take into account the
      new PHY framework. Correct the situation by adding a call to
      phy_set_mode() before phy_power_on().
      
      PHYs should also be handled at suspend/resume time. For this, call
      ahci_platform_enable/disable_phys() at suspend/resume_host() time. These
      calls are guarded by a HFLAG (AHCI_HFLAG_SUSPEND_PHYS) that the user of
      the libahci driver must set manually in hpriv->flags at probe time. This
      is to avoid breaking users that have not been tested with this change.
