Subject: [PATCH 0/2] Introduce ACPI support for ahci_platform driver

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):

    http://marc.info/?l=linux-arm-kernel&m=141083492521584&w=2

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)

Suravee Suthikulpanit (2):
  ACPI / scan: Add support for ACPI _CLS device matching
  ata: ahci_platform: Add ACPI _CLS matching
