Merge branch 'for-4.2' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/libata
Pull libata updates from Tejun Heo: - a number of libata core changes to better support NCQ TRIM. - ahci now supports MSI-X in single IRQ mode to support a new controller which doesn't implement MSI or INTX. - ahci now supports edge-triggered IRQ mode to support a new controller which for some odd reason did edge-triggered IRQ. - the usual controller support additions and changes. * 'for-4.2' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/libata: (27 commits) libata: Do not blacklist Micron M500DC ata: ahci_mvebu: add suspend/resume support ahci, msix: Fix build error for !PCI_MSI ahci: Add support for Cavium's ThunderX host controller ahci: Add generic MSI-X support for single interrupts to SATA PCI driver libata: finally use __initconst in ata_parse_force_one() drivers: ata: add support for Ceva sata host controller devicetree:bindings: add devicetree bindings for ceva ahci ahci: added support for Freescale AHCI sata ahci: Store irq number in struct ahci_host_priv ahci: Move interrupt enablement code to a separate function Doc: libata: Fix spelling typo found in libata.xml ata:sata_nv - Change 1 to true for bool type variable. ata: add Broadcom AHCI SATA3 driver for STB chips Documentation: devicetree: add Broadcom SATA binding libata: Fix regression when the NCQ Send and Receive log page is absent ata: hpt366: fix constant cast warning ata: ahci_xgene: potential NULL dereference in probe ata: ahci_xgene: Add AHCI Support for 2nd HW version of APM X-Gene SoC AHCI SATA Host controller. libahci: Add support to handle HOST_IRQ_STAT as edge trigger latch. ...
