Merge branch 'for-3.19' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/libata

Pull libata changes from Tejun Heo:
 "The only interesting piece is the support for shingled drives.  The
  changes in libata layer are minimal.  All it does is identifying the
  new class of device and report upwards accordingly"

* 'for-3.19' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/libata:
  libata: Remove FIXME comment in atapi_request_sense()
  sata_rcar: Document deprecated "renesas,rcar-sata"
  sata_rcar: Add clocks to sata_rcar bindings
  ahci_sunxi: Make AHCI_HFLAG_NO_PMP flag configurable with a module option
  libata-scsi: Update SATL for ZAC drives
