    Subject[PATCH 0/2] Introduce ACPI support for ahci_platform driver
    Date
    This patch series introduce ACPI support for non-PCI AHCI platform driver.
    Existing ACPI support for AHCI assumes the device controller is a PCI device.

    Also, since there is no ACPI _HID/_CID for generic AHCI controller, the driver
    could not use them for matching devices. Therefore, this patch introduces a mechanism
    for drivers to match devices using ACPI _CLS method.

    This patch series is rebased from:

    http://git.linaro.org/leg/acpi/acpi.git acpi-5.1-v6

    This topic was discussed earlier here (as part of introducing support for
    AMD Seattle SATA controller):

    Changes from RFC (https://lkml.org/lkml/2014/12/17/446)
    * Remove #ifdef and make non-ACPI version of the acpi_match_device_cls
    as inline. (per Arnd)
    * Simplify logic to retrieve and evaluate _CLS handle. (per Hanjun)

    ACPI / scan: Add support for ACPI _CLS device matching
    ata: ahci_platform: Add ACPI _CLS matching
