Merge tag 'upstream-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jgarzik/libata-dev

Browse Source 
Pull libata updates from Jeff Garzik:

1) apply, and then revert, the sysfs export of ATA host controller
   number.  Discussion was continuing after patch application, trying to
   figure out how to best mesh exported data with the installers,
   boot-time agents and other parties that want this info.

2) Merge Zero-Power Optical Device Driver (ZPODD) support, bringing the
   wonderfulness of sane power management to your CD/DVD device.

   Includes one SCSI-subsystem patch (with appropriate ACKs), adding
   runtime PM support to 'sr' driver.  That is the ZPODD interaction
   bits.

   Patchset went through some 13 revisions before it got here; kudos to
   Intel for persistence.

3) pata_samsung_cf: use devm_clk_get()

4) more ata_piix, ahci PCI IDs

5) Add SATA driver for R-Car SoC

6) Convert libata to use devm_ioremap_resource (Note: I think Greg sent
   this to you, also)

7) Set proper Sense Key (SK) in the SCSI simulator when ATA passthrough
   indicates check condition.  Google and specification hawks everywhere
   shall rejoice.

This option adds support for SATA ZPODD. It requires both
ODD and the platform support, and if enabled, will automatically
power on/off the ODD when certain condition is satisfied. This
does not impact user's experience of the ODD, only power is saved
when ODD is not in use(i.e. no disc inside).
