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"
