    Add Buddha PATA controller driver. It enables libata support for
    the Buddha, Catweasel and X-Surf expansion boards on the Zorro
    expansion bus.

    Module removal is currently unsupported (the old IDE's buddha
    driver also doesn't support it).

    After commit 5d32a66541c4 (PCI/ACPI: Allow ACPI to be built without
    CONFIG_PCI set) dependencies on CONFIG_PCI that previously were
    satisfied implicitly through dependencies on CONFIG_ACPI have to be
    specified directly. PATA_ACPI is a PCI device driver but the PCI
    dependency has not been explicitly called out.

  • b3cd92db6   ata: remove redundant 'default n' from Kconfig ... Browse Code »

    'default n' is the default value for any bool or tristate Kconfig
    setting so there is no need to write it explicitly.

    Also since commit f467c5640c29 ("kconfig: only write '# CONFIG_FOO
    is not set' for visible symbols") the Kconfig behavior is the same
    regardless of 'default n' being present or not:

    ...
    One side effect of (and the main motivation for) this change is making
    the following two definitions behave exactly the same:

    config FOO
    bool

    config FOO
    bool
    default n

    With this change, neither of these will generate a
    '# CONFIG_FOO is not set' line (assuming FOO isn't selected/implied).
    That might make it clearer to people that a bare 'default n' is
    redundant.

  • d55bac275   ata: Remove depends on HAS_DMA in case of platform dependency ... Browse Code »

    Remove dependencies on HAS_DMA where a Kconfig symbol depends on another
    symbol that implies HAS_DMA, and, optionally, on "|| COMPILE_TEST".
    In most cases this other symbol is an architecture or platform specific
    symbol, or PCI.

    Generic symbols and drivers without platform dependencies keep their
    dependencies on HAS_DMA, to prevent compiling subsystems or drivers that
    cannot work anyway.

    This simplifies the dependencies, and allows to improve compile-testing.

  • ebb82e3c7   ahci: Allow setting a default LPM policy for mobile chipsets ... Browse Code »

    On many laptops setting a different LPM policy then unknown /
    max_performance can lead to power-savings of 1.0 - 1.5 Watts (when idle).

    Modern ultrabooks idle around 6W (at 50% screen brightness), 1.0 - 1.5W
    is a significant chunk of this.

    There are some performance / latency costs to enabling LPM by default,
    so it is desirable to make it possible to set a different LPM policy
    for mobile / laptop variants of chipsets / "South Bridges" vs their
    desktop / server counterparts. Also enabling LPM by default is not
    entirely without risk of regressions. At least min_power is known to
    cause issues with some disks, including some reports of data corruption.

    This commits adds a new ahci.mobile_lpm_policy kernel cmdline option,
    which defaults to a new SATA_MOBILE_LPM_POLICY Kconfig option so that
    Linux distributions can choose to set a LPM policy for mobile chipsets
    by default.

    The reason to have both a kernel cmdline option and a Kconfig default
    value for it, is to allow easy overriding of the default to allow
    trouble-shooting without needing to rebuild the kernel.

  • b24413180   License cleanup: add SPDX GPL-2.0 license identifier to files with no license ... Browse Code »

    Many source files in the tree are missing licensing information, which
    makes it harder for compliance tools to determine the correct license.

    By default all files without license information are under the default
    license of the kernel, which is GPL version 2.

    Update the files which contain no license information with the 'GPL-2.0'
    SPDX license identifier. The SPDX identifier is a legally binding
    shorthand, which can be used instead of the full boiler plate text.

    This patch is based on work done by Thomas Gleixner and Kate Stewart and
    Philippe Ombredanne.

    How this work was done:

    Patches were generated and checked against linux-4.14-rc6 for a subset of
    the use cases:
    - file had no licensing information it it.
    - file was a */uapi/* one with no licensing information in it,
    - file was a */uapi/* one with existing licensing information,

    Further patches will be generated in subsequent months to fix up cases
    where non-standard license headers were used, and references to license
    had to be inferred by heuristics based on keywords.

    The analysis to determine which SPDX License Identifier to be applied to
    a file was done in a spreadsheet of side by side results from of the
    output of two independent scanners (ScanCode & Windriver) producing SPDX
    tag:value files created by Philippe Ombredanne. Philippe prepared the
    base worksheet, and did an initial spot review of a few 1000 files.

    The 4.13 kernel was the starting point of the analysis with 60,537 files
    assessed. Kate Stewart did a file by file comparison of the scanner
    results in the spreadsheet to determine which SPDX license identifier(s)
    to be applied to the file. She confirmed any determination that was not
    immediately clear with lawyers working with the Linux Foundation.

    Criteria used to select files for SPDX license identifier tagging was:
    - Files considered eligible had to be source code files.
    - Make and config files were included as candidates if they contained >5
    lines of source
    - File already had some variant of a license header in it (even if

  • be4e456ed   ata: Add driver for Faraday Technology FTIDE010 ... Browse Code »

    This adds a driver for the Faraday Technology FTIDE010
    PATA IP block.

    When used with the Storlink/Storm/Cortina Systems Gemini
    SoC, the PATA interface is accompanied by a PATASATA
    bridge, so while the device appear as a PATA controller,
    it attaches physically to SATA disks, and also has a
    designated memory area with registers to set up the bridge.

    The Gemini SATA bridge is separated into its own driver
    file to make things modular and make it possible to reuse
    the PATA driver as stand-alone on other systems than the
    Gemini.

    The IP suffers from the same PMP issue the DA850 does - if we enable

    This makes the code calling into the hwmon subsystem compile-time
    conditional, and adds a Kconfig dependency to avoid the corner
    case of having HWMON=m and AHCI_IMX=y, by forcing AHCI_IMX=m in this
    case. The thermal subsystem already has a check in its header, but
    that also doesn't cover the THERMAL=m case, so we need a somewhat
    complex Kconfig expression to handle all cases.

    The dwc_460ex SATA driver has become available on non-powerpc architectures
    and may cause randconfig build errors when CONFIG_DMADEVICES is not set
    and SATA_DWC_OLD_DMA is enabled:

    ERROR: "dw_dma_remove" [drivers/ata/sata_dwc_460ex.ko] undefined!

    This adds an explcit Kconfig dependency to CONFIG_SATA_DWC so we
    cannot run into broken configurations. While it would also be
    possible to build the driver with both CONFIG_DMADEVICES
    and SATA_DWC_OLD_DMA disabled, that case is not useful because
    there is no fallback to PIO mode when the DMA engine is not
    usable.

  • 1980eb9bd   ata: ahci_brcmstb: add support for MIPS-based platforms ... Browse Code »

    The BCM7xxx ARM-based and MIPS-based platforms share a similar hardware
    block for AHCI SATA3.

    This new compatible string, "brcm,bcm7425-ahci", may be used for most
    MIPS-based platforms of 40nm process technology.

  • ecfb45985   ahci: added a new driver for supporting Freescale AHCI sata ... Browse Code »

    Currently Freescale QorIQ series SATA is supported by ahci_platform
    driver. Some SoC specific settings have been put in uboot. So whether
    SATA works or not heavily depends on uboot.
    This patch will add a new driver to support QorIQ sata which removes
    the dependency on any other boot loader.
    Freescale QorIQ series sata, like ls1021a ls2085a ls1043a, is
    compatible with serial ATA 3.0 and AHCI 1.3 specification.
