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- the deperecated pci_ dma API usages have been replaced by dma_ ones.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
libata-eh: Set 'information' field for autosense
libata: Implement support for sense data reporting
libata: Implement NCQ autosense
libata: use status bit definitions in ata_dump_status()
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
ata: sata_mv: add proper definitions for LP_PHY_CTL register values
