[PATCH V6 0/2] Add ACPI support for HiSilicon SoCs Host Controllers

Show all headers | View raw

This patchset adds ACPI support for the HiSilicon Hip05/Hip06/Hip07 SoC
PCIe controllers.
The two patches respectively:
        - provides the common function acpi_get_rc_resources() for ARM64
          platform.
        - adds the HiSilicon ACPI specific quirks.

This patchset is based on branch pci/ecam-v6
It can be found here:
https://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci.git(pci/ecam-v6)

This patchset has been tested on HiSilicon D03 board.
The dmesg log, /proc/iomem, and ACPI table information can be found:
https://bugzilla.kernel.org/show_bug.cgi?id=187961

v5 -> v6:
- change the config option to CONFIG_PCI_ECAM_QUIRKS.
- fix some commets about acpi_get_rc_resources().

v4 -> v5:
- obtain rc base addresses from PNP0C02 at the root of the ACPI
  namespace (under \_SB) instead of from sub-device under the RC.
- merge the rewrited get rc resources code by Tomasz.
- delete unused code. 
- drop the PATCH V4 1/2, will rework late as a separate patch.

v3 -> v4:
- rebase on pci/ecam-v6.
- delete the unnecessary link_up check code. 

v2 -> v3:
- rebase against 4.9-rc1 and add Tomasz quirks V6 pathcset. 
- obtain rc base addresses from PNP0C02 as subdevice of PNP0A03 instead of
  hardcode the addresses.
- modify hisi_pcie_acpi_rd_conf/hisi_pcie_acpi_wr_conf() according to
  Arnd comments.

v1 -> v2:
- rebase against Tomasz RFC V5 quirk mechanism
- add ACPI support for the HiSilicon Hip07 SoC PCIe controllers.
