Merge tag 'ata-6.20-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/libata/linux

Pull ATA updates from Damien Le Moal:

 - Cleanup IRQ masking in the handling of completed report zones
   commands (Niklas)

 - Improve the handling of Thunderbolt attached devices to speed up
   device removal (Henry)

 - Several patches to generalize the existing max_sec quirks to
   facilitates quirking the maximum command size of buggy drives, many
   of which have recently showed up with the recent increase of the
   default max_sectors block limit (Niklas)

 - Cleanup the ahci-platform and sata dt-bindings schema (Rob,
   Manivannan)

 - Improve device node scan in the ahci-dwc driver (Krzysztof)

 - Remove clang W=1 warnings with the ahci-imx and ahci-xgene drivers
   (Krzysztof)

 - Fix a long standing potential command starvation situation with
   non-NCQ commands issued when NCQ commands are on-going (me)

 - Limit max_sectors to 8191 on the INTEL SSDSC2KG480G8 SSD (Niklas)

 - Remove Vesa Local Bus (VLB) support in the pata_legacy driver (Ethan)

 - Simple fixes in the pata_cypress (typo) and pata_ftide010 (timing)
   drivers (Ethan, Linus W)
