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. ...

+Binding for CEVA AHCI SATA Controller
+
+Required properties:
+ - reg: Physical base address and size of the controller's register area.
+ - compatible: Compatibility string. Must be 'ceva,ahci-1v84'.
+ - clocks: Input clock specifier. Refer to common clock bindings.
+ - interrupts: Interrupt specifier. Refer to interrupt binding.
+
+Optional properties:
+ - ceva,broken-gen2: limit to gen1 speed instead of gen2.
+
+Examples:
+ ahci@fd0c0000 {
+ compatible = "ceva,ahci-1v84";
+ reg = <0xfd0c0000 0x200>;
+ interrupt-parent = <&gic>;
+ interrupts = <0 133 4>;
+ clocks = <&clkc SATA_CLK_ID>;
+ ceva,broken-gen2;
+ };
