      ata: libahci_platform: Convert to using devm bulk clocks API · e28b3abf
      Serge Semin authored
      In order to simplify the clock-related code there is a way to convert the
      current fixed clocks array into using the common bulk clocks kernel API
      with dynamic set of the clock handlers and device-managed clock-resource
      tracking. It's a bit tricky due to the complication coming from the
      requirement to support the platforms (da850, spear13xx) with the
      non-OF-based clock source, but still doable.
      
      Before this modification there are two methods have been used to get the
      clocks connected to an AHCI device: clk_get() - to get the very first
      clock in the list and of_clk_get() - to get the rest of them. Basically
      the platforms with non-OF-based clocks definition could specify only a
      single reference clock source. The platforms with OF-hw clocks have been
      luckier and could setup up to AHCI_MAX_CLKS clocks. Such semantic can be
      retained with using devm_clk_bulk_get_all() to retrieve the clocks defined
      via the DT firmware and devm_clk_get_optional() otherwise. In both cases
      using the device-managed version of the methods will cause the automatic
      resources deallocation on the AHCI device removal event. The only
      complicated part in the suggested approach is the explicit allocation and
      initialization of the clk_bulk_data structure instance for the non-OF
      reference clocks. It's required in order to use the Bulk Clocks API for
      the both denoted cases of the clocks definition.
      
      Note aside with the clock-related code reduction and natural
      simplification, there are several bonuses the suggested modification
      provides. First of all the limitation of having no greater than
      AHCI_MAX_CLKS clocks is now removed, since the devm_clk_bulk_get_all()
      method will allocate as many reference clocks data descriptors as there
      are clocks specified for the device. Secondly the clock names are
      auto-detected. So the LLDD (glue) drivers can make sure that the required
      clocks are specified just by checking the clock IDs in the clk_bulk_data
      array.  Thirdly using the handy Bulk Clocks kernel API improves the
      clocks-handling code readability. And the last but not least this
      modification implements a true optional clocks support to the
      ahci_platform_get_resources() method. Indeed the previous clocks getting
      procedure just stopped getting the clocks on any errors (aside from
      non-critical -EPROBE_DEFER) in a way so the callee wasn't even informed
      about abnormal loop termination. The new implementation lacks of such
      problem. The ahci_platform_get_resources() will return an error code if
      the corresponding clocks getting method ends execution abnormally.

      ata: libahci_platform: Convert to using platform devm-ioremap methods · 82d437e6
      Serge Semin authored
      Currently the IOMEM AHCI registers space is mapped by means of the
      two functions invocation: platform_get_resource() is used to get the very
      first memory resource and devm_ioremap_resource() is called to remap that
      resource. Device-managed kernel API provides a handy wrapper to perform
      the same in single function call: devm_platform_ioremap_resource().
      
      While at it seeing many AHCI platform drivers rely on having the AHCI CSR
      space marked with "ahci" name let's first try to find and remap the CSR
      IO-mem with that name and only if it fails fallback to getting the very
      first registers space platform resource.

      dt-bindings: ata: sata-brcm: Apply common AHCI schema · 2ea4d52a
      Serge Semin authored
      The Broadcom SATA controller is obviously based on the AHCI standard. The
      device driver uses the kernel AHCI library to work with it. Therefore we
      can be have a more thorough DT-bindings evaluation by referring to the
      AHCI-common schema instead of using the more relaxed SATA-common one.

      dt-bindings: ata: sata: Extend number of SATA ports · 388f08ec
      Serge Semin authored
      The denoted in the description upper limit only concerns the Port
      Multipliers, but not the actual SATA ports. It's an external device
      attached to a SATA port in order to access more than one SATA-drive. So
      when it's attached to a SATA port it just extends the port capability
      while the number of actual SATA ports stays the same. For instance on AHCI
      controllers the number of actual ports is determined by the CAP.NP field
      and the PI (Ports Implemented) register. AFAICS in general the maximum
      number of SATA ports depends on the particular controller implementation.
      Generic AHCI controller can't have more than 32 ports (since CAP.NP is of
      5 bits wide and PI register is 32-bits size), while DWC AHCI SATA
      controller can't be configured with more than 8 ports activated. So let's
      discard the SATA ports reg-property restrictions and just make sure that
      it consists of a single reg-item.

      Indeed in accordance with what is implemented in the AHCI platform driver
      and the way the AHCI DT nodes are defined in the DT files we can add the
      next AHCI DT properties constraints: AHCI CSR ID is fixed to 'ahci', PHY
      name is fixed to 'sata-phy', AHCI controller can't have more than 32 ports
      by design, AHCI controller can have up to 32 IRQ lines.

      dt-bindings: ata: ahci-platform: Detach common AHCI bindings · 0f3680ed
      Serge Semin authored
      In order to create a more sophisticated AHCI controller DT bindings let's
      divide the already available generic AHCI platform YAML schema into the
      platform part and a set of the common AHCI properties. The former part
      will be used to evaluate the AHCI DT nodes mainly compatible with the
      generic AHCI controller while the later schema will be used for more
      thorough AHCI DT nodes description. For instance such YAML schemas design
      will be useful for our DW AHCI SATA controller derivative with four clock
      sources, two reset lines, one system controller reference and specific
      max Rx/Tx DMA xfers size constraints.
      
      Note the phys and target-supply property requirement is preserved in the
      generic AHCI platform bindings because some platforms can lack of the
      explicitly specified PHYs or target device power regulators.
      
      Also note the SATA/AHCI ports properties have been moved to the
      $defs-paragraph of the schemas. It's done in order to create the
      extendable properties hierarchy such that particular AHCI-controller
      could add vendor-specific port properties.

      let's permit the device nodes being equipped with the dma-coherent
      property in case if the platform is capable of cache-coherent DMAs.
      
      As a side-effect we can drop the explicit dma-coherent property definition
      from the particular device schemas. Currently it concerns the Broadcom
      SATA AHCI controller only.

      ata: make PATA_PLATFORM selectable only for suitable architectures · d3243965
      Lukas Bulwahn authored
      It is currently possible to select "Generic platform device PATA support"
      in two situations:
      
        - architecture allows the generic platform device PATA support and
          indicates that with "select HAVE_PATA_PLATFORM".
        - if the user claims to be an EXPERT by setting CONFIG_EXPERT to yes
      
      However, there is no use case to have Generic platform device PATA support
      in a kernel build if the architecture definition, i.e., the selection of
      configs by an architecture, does not support it.
      
      If the architecture definition is wrong, i.e., it just misses a 'select
      HAVE_PATA_PLATFORM', then even an expert that configures the kernel build
      should not just fix that by overruling the claimed support by an
      architecture. If the architecture definition is wrong, the expert should
      just provide a patch to correct the architecture definition instead---in
      the end, if the user is an expert, sending a quick one-line patch should
      not be an issue.
      
      In other words, I do not see the deeper why an expert can overrule the
      architecture definition in this case, as the expert may not overrule the
      config selections defined by the architecture in the large majority
      ---or probably all other (modulo some mistakes)---of similar cases.

      ata: clean up how architectures enable PATA_PLATFORM and PATA_OF_PLATFORM · 3ebe59a5
      Lukas Bulwahn authored
      There are two options for platform device PATA support:
      
        PATA_PLATFORM: Generic platform device PATA support
        PATA_OF_PLATFORM: OpenFirmware platform device PATA support
      
      If an architecture allows the generic platform device PATA support, it
      shall select HAVE_PATA_PLATFORM. Then, Generic platform device PATA support
      is available and can be selected.
      
      If an architecture has OpenFirmware support, which it indicates by
      selecting OF, OpenFirmware platform device PATA support is available
      and can be selected.
      If OpenFirmware platform device PATA support is selected, then the
      functionality (code files) from Generic platform device PATA support needs
      to be integrated in the kernel build for the OpenFirmware platform device
      PATA support to work. Select PATA_PLATFORM in PATA_OF_PLATFORM to make sure
      the needed files are added in the build.
      
      So, architectures with OpenFirmware support, do not need to additionally
      select HAVE_PATA_PLATFORM. It is only needed by architecture that want the
      non-OF pata-platform module.
      
      Reflect this way of intended use of config symbols in the ata Kconfig and
      adjust all architecture definitions.
      
      This follows the suggestion from Arnd Bergmann (see Link).

       - Ensure we never emit lwarx with EH=1 on 32-bit, because some 32-bit

      afs: Enable multipage folio support · 8549a263
      David Howells authored
      Enable multipage folio support for the afs filesystem.
      
      Support has already been implemented in netfslib, fscache and cachefiles
      and in most of afs, but I've waited for Matthew Wilcox's latest folio
      changes.
      
      Note that it does require a change to afs_write_begin() to return the
      correct subpage.  This is a "temporary" change as we're working on
      getting rid of the need for ->write_begin() and ->write_end()
      completely, at least as far as network filesystems are concerned - but
      it doesn't prevent afs from making use of the capability.

      perf test: Refactor shell tests allowing subdirs · 7391db64
      Carsten Haitzler authored
      This is a prelude to adding more tests to shell tests and in order to
      support putting those tests into subdirectories, I need to change the
      test code that scans/finds and runs them.
      
      To support subdirs I have to recurse so it's time to refactor the code
      to allow this and centralize the shell script finding into one location
      and only one single scan that builds a list of all the found tests in
      memory instead of it being duplicated in 3 places.
      
      This code also optimizes things like knowing the max width of desciption
      strings (as we can do that while we scan instead of a whole new pass of
      opening files).
      
      It also more cleanly filters scripts to see only *.sh files thus
      skipping random other files in directories like *~ backup files, other
      random junk/data files that may appear and the scripts must be
      executable to make the cut (this ensures the script lib dir is not seen
      as scripts to run).
      
      This avoids perf test running previous older versions of test scripts
      that are editor backup files as well as skipping perf.data files that
      may appear and so on.
