Merge branch 'for-3.15' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/libata
Pull libata updates from Tejun Heo: "A lot of activities on libata side this time. - A lot of changes around ahci. Various embedded platforms are implementing ahci controllers. Some were built atop ahci_platform, others were doing their own things. Hans made some structural changes to libahci and librarized ahci_platform so that ahci platform drivers can share more common code. A couple platform drivers are added on top of that and several are added to replace older drivers which were doing their own things (older ones are scheduled to be removed). - Dan finishes the patchset to make libata PM operations asynchronous. Combined with one patch being routed through scsi, this should speed resume measurably. - Various fixes and cleanups from Bartlomiej and others" * 'for-3.15' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/libata: (61 commits) ata: fix Marvell SATA driver dependencies ata: fix ARASAN CompactFlash PATA driver dependencies ata: remove superfluous casts ata: sata_highbank: remove superfluous cast ata: fix Calxeda Highbank SATA driver dependencies ata: fix R-Car SATA driver dependencies ARM: davinci: da850: update SATA AHCI support ata: add new-style AHCI platform driver for DaVinci DA850 AHCI controller ata: move library code from ahci_platform.c to libahci_platform.c ata: ahci_platform: fix ahci_platform_data->suspend method handling libata: remove unused ata_sas_port_async_resume() stub libata.h: add stub for ata_sas_port_resume libata: async resume libata, libsas: kill pm_result and related cleanup ata: Fix compiler warning with APM X-Gene host controller driver arm64: Add APM X-Gene SoC AHCI SATA host controller DTS entries ata: Add APM X-Gene SoC AHCI SATA host controller driver Documentation: Add documentation for the APM X-Gene SoC SATA host controller DTS binding arm64: Add APM X-Gene SoC 15Gbps Multi-purpose PHY DTS entries ata: ahci_sunxi: fix code formatting ...
