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 - the deperecated pci_ dma API usages have been replaced by dma_ ones.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