  • 09c434b8a   treewide: Add SPDX license identifier for more missed files ... Browse Code »

    Add SPDX license identifiers to all files which:

    - Have no license information of any form

    - Have MODULE_LICENCE("GPL*") inside which was used in the initial
    scan/conversion to ignore the file

    These files fall under the project license, GPL v2 only. The resulting SPDX
    license identifier is:

    GPL-2.0-only

  • d872ced29   ata: sata_gemini: Introduce explicit IDE pin control ... Browse Code »

    The IDE pins are managed by the pin controller, if we want to
    use these, we need to ask the pin controller to explicitly enable
    them as by default, these pins are used for other business and
    most users just rely on the SATA bridge.

  • d99058a23   ata: sata_gemini: Retire custom pin control ... Browse Code »

    I added a proper pin control driver for the Gemini SoC, so retire
    this custom code and rely on the pin controller to set up the pads.

    The "IOMUX" which is routing signals between the ATA and SATA
    bridge inside of the chip is not about pin control and remains in
    place.

  • afbd39a42   ata: sata_gemini: explicitly request exclusive reset control ... Browse Code »

    Commit a53e35db70d1 ("reset: Ensure drivers are explicit when requesting
    reset lines") started to transition the reset control request API calls
    to explicitly state whether the driver needs exclusive or shared reset
    control behavior. Convert all drivers requesting exclusive resets to the
    explicit API call so the temporary transition helpers can be removed.

    No functional changes.

  • cea9c8d34   ata: Drop unnecessary static ... Browse Code »

    Drop static on a local variable, when the variable is initialized before
    any possible use. Thus, the static has no benefit.

    The semantic patch that fixes this problem is as follows:
    (http://coccinelle.lip6.fr/)

    //
    @bad exists@
    position p;
    identifier x;
    type T;
    @@
    static T x@p;
    ...
    x =

    @@
    identifier x;
    expression e;
    type T;
    position p != bad.p;
    @@
    -static
    T x@p;
    ... when != x
    when strict
    ?x = e;

  • 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.

    dmesg excerpt from the D-Link DIR-685 storage router:
