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.

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.

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.

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.

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.

Seeing doubtfully any SATA device working without embedded DMA engine 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.

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.

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).

The ACPI_FADT_LOW_POWER_S0 flag merely means that it is better to use low-power S0 idle on the given platform than S3 (provided that the latter is supported) and it doesn't preclude using either of them (which of them will be used depends on the choices made by user space). For this reason, there is no benefit from checking that flag in ahci_update_initial_lpm_policy(). First off, it cannot be a bug to do S3 with policy set to either ATA_LPM_MIN_POWER_WITH_PARTIAL or ATA_LPM_MIN_POWER, because S3 can be used on systems with ACPI_FADT_LOW_POWER_S0 set and it must work if really supported, so the ACPI_FADT_LOW_POWER_S0 check is not needed to protect the S3-capable systems from failing. Second, suspend-to-idle can be carried out on a system with ACPI_FADT_LOW_POWER_S0 unset and it is expected to work, so if setting policy to either ATA_LPM_MIN_POWER_WITH_PARTIAL or ATA_LPM_MIN_POWER is needed to handle that case correctly, it should be done regardless of the ACPI_FADT_LOW_POWER_S0 value. Accordingly, replace the ACPI_FADT_LOW_POWER_S0 check in ahci_update_initial_lpm_policy() with pm_suspend_default_s2idle() which is more general and also takes the user's preference into account and drop the CONFIG_ACPI #ifdef around it that is not necessary any more.

ata_dev_set_feature() is currently used for enabling/disabling any ATA feature, e.g. SETFEATURES_SPINUP and SETFEATURE_SENSE_DATA, i.e. it is not only used to enable/disable SATA specific features. For most features, the enable/disable bit is specified in the subcommand specific field "count". It is only for the specific subcommands "Enable SATA feature" (0x10) and "Disable SATA feature" (0x90) where the field "count" is used to specify a feature instead of enable/disable. The parameter names for this function are thus quite misleading. Rename the parameter names to be more generic and in line with ACS-5, and remove the references to "SATA FEATURES" in the kernel-doc.

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.

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.
