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 and tested with: http://git.linaro.org/leg/acpi/acpi.git acpi-5.1-v7 This topic was discussed earlier here (as part of introducing support for AMD Seattle SATA controller): http://marc.info/?l=linux-arm-kernel&m=141083492521584&w=2 NOTE: * PATCH 2/2 has already been Acked-by Tejun Heo in V1. I only made a minor renaming of the acpi_cls to acpi_match_cls for clarity in V2. It probably should be routed together with the PATCH 1/2 (once acked) since it defines the new member in the struct. Changes V1 (https://lkml.org/lkml/2014/12/19/345) * Rebased to 3.19.0-rc2 * Change from acpi_cls in device_driver to acpi_match_cls (Hanjun comment) * Change the matching logic in acpi_driver_match_device() due to the new special PRP0001 _HID. * Simplify the return type of acpi_match_device_cls() to boolean. 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.
