Merge tag 'ata-6.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/libata/linux

Pull ata updates from Niklas Cassel:

 - 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 (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) (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.

   New platforms can be added using board type board_ahci, which will
   not have the quirk applied (me)

 - Rename board_ahci_nosntf to board_ahci_pcs_quirk_no_sntf to more
   clearly highlight that it applies two different quirks (me)

 - Modify the ahci_broken_devslp() quirk to be implemented like all the
   other quirks (i.e. define a board type for the quirk) (me)

 - Drop unused board_ahci_noncq board type (me)

 - Rename board_ahci_nomsi to board_ahci_no_msi to match the other board
   types (me)

 - Make pata_parport_bus_type const (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 (Rafał Miłecki)

 - At boot, print the number of implemented ports, instead of printing
   the maximum number of ports supported by the HBA silicon (me)

-MediaTek Serial ATA controller
-
-Required properties:
- - compatible	   : Must be "mediatek,<chip>-ahci", "mediatek,mtk-ahci".
-		     When using "mediatek,mtk-ahci" compatible strings, you
-		     need SoC specific ones in addition, one of:
-		     - "mediatek,mt7622-ahci"
- - reg		   : Physical base addresses and length of register sets.
- - interrupts	   : Interrupt associated with the SATA device.
- - interrupt-names : Associated name must be: "hostc".
- - clocks	   : A list of phandle and clock specifier pairs, one for each
-		     entry in clock-names.
- - clock-names	   : Associated names must be: "ahb", "axi", "asic", "rbc", "pm".
- - phys		   : A phandle and PHY specifier pair for the PHY port.
- - phy-names	   : Associated name must be: "sata-phy".
- - ports-implemented : See ./ahci-platform.txt for details.
-
-Optional properties:
- - power-domains   : A phandle and power domain specifier pair to the power
-		     domain which is responsible for collapsing and restoring
-		     power to the peripheral.
- - resets	   : Must contain an entry for each entry in reset-names.
-		     See ../reset/reset.txt for details.
- - reset-names	   : Associated names must be: "axi", "sw", "reg".
- - mediatek,phy-mode : A phandle to the system controller, used to enable
-		       SATA function.

-Example:
-
-	sata: sata@1a200000 {
-		compatible = "mediatek,mt7622-ahci",
