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