Linus Torvalds 57aaf9134c ata changes for 6.9-rc1
- Do not enable LPM for external ports (hotplug-capable ports or eSATA
    ports), as the HBA will not be able to detect hot plug removal events
    when LPM is enabled. (from me)
 
  - Drop the board type board_ahci_low_power. Now when we make sure that we
    won't enable LPM for external ports, we can always set the LPM policy to
    CONFIG_SATA_MOBILE_LPM_POLICY for internal ports. There is thus no
    longer any need for the board type board_ahci_low_power, so it can be
    removed. (As before, LPM features not supported by the HBA and/or the
    device will not be enabled, regardless of the LPM policy Kconfig.)
    (from Mario Limonciello)
 
    Note that the default CONFIG_SATA_MOBILE_LPM_POLICY value is still 0
    (which will not try to enable any LPM features), however, most Linux
    distributions override this and set it to 3 (Medium power with DIPM).
    We intend to change the default to 3 in the coming cycles, but we will
    wait a cycle or two.
 
  - Add board type board_ahci_pcs_quirk and make all legacy Intel platforms
    use it. The Intel PCS quirk was being applied to basically all Intel
    platforms, which caused some issues (the device failing to come back
    after a reset), when being applied to newer Intel platforms where it
    shouldn't have been applied. Add board type board_ahci_pcs_quirk and
    make legacy Intel platforms use it. New platforms can be added using
    board type board_ahci (which will not have the quirk applied).
    (from me)
 
  - Rename board_ahci_nosntf to board_ahci_pcs_quirk_no_sntf to more clearly
    highlight that it applies two different quirks. (from me)
 
  - Modify the ahci_broken_devslp() quirk to be implemented like all the
    other quirks (i.e. define a board type for the quirk). (from me)
 
  - Drop unused board_ahci_noncq board type. (from me)
 
  - Rename board_ahci_nomsi to board_ahci_no_msi to match the other board
    types. (from me)
 
  - Make pata_parport_bus_type const. (from Ricardo B. Marliere)
 
  - Remove at91 compact flash device tree binding. (The binding is not used
    by any driver.) (from Hari Prasath Gujulan Elango)
 
  - Convert MediaTek device tree binding to json-schema.
    (from Rafał Miłecki)
 
  - At boot, print the number of implemented ports, instead of printing the
    maximum number of ports supported by the HBA silicon. (from me)
