Merge branch 'for-4.1' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/libata

Pull libata updates from Tejun Heo:

 - Hannes's patchset implements support for better error reporting
   introduced by the new ATA command spec.

 - the deperecated pci_ dma API usages have been replaced by dma_ ones.

 - a bunch of hardware specific updates and some cleanups.

* 'for-4.1' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/libata:
  ata: remove deprecated use of pci api
  ahci: st: st_configure_oob must be called after IP is clocked.
  ahci: st: Update the ahci_st DT documentation
  ahci: st: Update the DT example for how to obtain the PHY.
  sata_dwc_460ex: indent an if statement
  libata: Add tracepoints

  ide,ata: Rename ATA_IDX to ATA_SENSE
  libata: whitespace fixes in ata_to_sense_error()
  libata: whitespace cleanup in ata_get_cmd_descript()
  libata: use READ_LOG_DMA_EXT
  libata: remove ATA_FLAG_LOWTAG
  sata_dwc_460ex: re-use hsdev->dev instead of dwc_dev
  sata_dwc_460ex: move to generic DMA driver
  sata_dwc_460ex: join messages back
  sata: xgene: add ACPI support for APM X-Gene SATA ports
