Merge tag 'ata-7.3' of git://git.kernel.org/pub/scm/linux/kernel/git/libata/linux

Pull ata updates from Damien Le Moal:

 - Some code cleanups to rename the function used to identify ZAC
   devices and declare some local functions static (me)

 - Refactoring and improvement of the translation of the SCSI REPORT
   SUPPORTED OPCODES command to allow users access to the entire list of
   supported commands (me)

 - Fix the translation of the WRITE SAME command with UNMAP bit set (DSM
   TRIM) for devices with a sector size larger than 2K and devices that
   support multiple TRIM segments (Niklas)

 - Add support detecting support for and translating the SCSI commands
   related to the storage elements depopulation feature (GET PHYSICAL
   ELEMENT STATUS, REMOVE ELEMENT AND TRUCATE, REMOVE ELEMENT AND MODIFY
   ZONES and RESTORE ELEMENTS AND REBUILD) (me)

 - Improvements to the sata_mv driver probe code (clocks and IRQ
   initialization) (Rosen)

 - Improve resource initialization in the pata_rb532_cf, pata_pxa,
   sata_highbank and ahci_da850 drivers (Rosen)

 - Improve PIO data-in command completions to better hndle slow devices,
   e.g. CF cards (Richard)

 - Improve the DMA channel management using device resources in the
   pata_pxa driver (Rosen)

 - Fix the pata_ep93xx driver to correctly fallback to PIO mode if DMA
   initialization fails (Rosen)

 - Use named initializers to define the match tables of the ahci_xgene,
   ahci_qoriq and ahci_platform drivers (Pawel)
