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.

AHCI: Support multiple MSIs

2013-01-24T16:25:13+00:00

Take advantage of multiple MSIs implementation on x86 - on
systems with IRQ remapping AHCI ports not only get assigned
separate MSI vectors - but also separate IRQs. As result,
interrupts generated by different ports could be serviced on
different CPUs rather than on a single one.

In cases when number of allocated MSIs is less than requested
the Sharing Last MSI mode does not get used, no matter
implemented in hardware or not. Instead, the driver assumes the
advantage of multiple MSIs is negated and falls back to the
single MSI mode as if MRSM bit was set (some Intel chips
implement this strategy anyway - MRSM bit gets set even if the
number of allocated MSIs exceeds the number of implemented ports).

ahci: Add identifiers for ASM106x devices

2012-09-13T04:24:29+00:00

They don't always appear as AHCI class devices but instead as IDE class.

This can also appear as 0x9192. Reported in bugzilla and confirmed with the
board documentation for these boards.

ahci: Add JMicron 362 device IDs

2012-09-13T04:23:12+00:00

The JMicron JMB362 controller supports AHCI only, but some revisions
use the IDE class code.  These need to be matched by device ID.

These additions have apparently been included by QNAP in their NAS
devices using these controllers.
