Merge branch 'for-4.4' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/libata
Pull libata updates from Tejun Heo: "Most are ahci and other device specific additions. Dan cleaned up ahci IRQ handling to prepare for future MSIX changes. On the libata core side, Vinayak updated SG handling so that NCQ commands can be issued through SG_IO and Christoph cleaned up code a bit. There's one merge from for-4.3-fixes to include a pata_macio commit that didn't get pushed out" * 'for-4.4' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/libata: ahci: add new Intel device IDs ahci: Add Marvell 88se91a2 device id ahci: cleanup ahci_host_activate_multi_irqs ahci: ahci_host_activate: kill IRQF_SHARED devicetree: bindings: Fixed a few typos ahci: qoriq: Disable NCQ on ls2080a SoC ahci: qoriq: Rename LS2085A SoC support code to LS2080A libata: enable LBA flag in taskfile for ata_scsi_pass_thru() libata: add support for NCQ commands for SG interface ahci: qoriq: Fix a compiling warning pata_it821x: use "const char *" for string literals libata: only call ->done once all per-tag ressources are released libata: cleanup ata_scsi_qc_complete ata: ahci: find eSATA ports and flag them as removable libata: samsung_cf: fix handling platform_get_irq result ata: pata_macio: Fix module autoload for OF platform driver ata: pata_pxa: dmaengine conversion ahci: added a new driver for supporting Freescale AHCI sata devicetree:bindings: add devicetree bindings for Freescale AHCI Revert "ahci: added support for Freescale AHCI sata"

+Binding for Freescale QorIQ AHCI SATA Controller
+
+Required properties:
+ - reg: Physical base address and size of the controller's register area.
+ - compatible: Compatibility string. Must be 'fsl,<chip>-ahci', where
+ chip could be ls1021a, ls2080a, ls1043a etc.
+ - clocks: Input clock specifier. Refer to common clock bindings.
+ - interrupts: Interrupt specifier. Refer to interrupt binding.
+
+Optional properties:
+ - dma-coherent: Enable AHCI coherent DMA operation.
+ - reg-names: register area names when there are more than 1 register area.
+
+Examples:
+ sata@3200000 {
+ compatible = "fsl,ls1021a-ahci";
+ reg = <0x0 0x3200000 0x0 0x10000>;
+ interrupts = <GIC_SPI 101 IRQ_TYPE_LEVEL_HIGH>;
+ clocks = <&platform_clk 1>;
+ dma-coherent;
+ };
