Merge branch 'for-4.5' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/libata
Pull libata updates from Tejun Heo: "Mostly low level driver specific changes. Two changes are somewhat noteworthy. First, Dan's patchset to support per-port msix interrupt handling for ahci, which was tried last cycle but had to be backed out due to a couple issues, is back and seems to be working fine. Second, libata exception handling now uses usleep_range() instead of msleep() for sleeps < 20ms which can make things snappier in some corner cases" * 'for-4.5' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/libata: libata: skip debounce delay on link resume ata: ahci_brcmstb: disable DIPM support ata: ahci_brcmstb: enable support for ALPM drivers: libata-core: Use usleep_range() instead of msleep() for short sleeps (<20 ms) sata_sx4: correctly handling failed allocation ata: ahci_brcmstb: add support for MIPS-based platforms ahci: qoriq: Adjust the default register values on ls1021a ahci: qoriq: Update the default Rx watermark value ahci: qoriq: Adjust the default register values on ls1043a ahci: compile out msi/msix infrastructure ata: core: fix irq description on AHCI single irq systems ata: ahci_brcmstb: remove unused definitions ata: ahci_brcmstb: add a quirk for MIPS-based platforms ata: ahci_brcmstb: disable NCQ for MIPS-based platforms ata: sata_rcar: Remove obsolete platform_device_id entries sata_rcar: Add compatible string for r8a7795 ahci: kill 'intr_status' ahci: switch from 'threaded' to 'hardirq' interrupt handling ahci: per-port msix support
