Merge branch 'stericsson/cleanup' into next/timer
The timer and cleanup branches from stericsson conflict,
so I'm merging them here.

+What: /sys/class/scsi_host/hostX/isci_id
+Date: June 2011
+Contact: Dave Jiang <dave.jiang@intel.com>
+Description:
+ This file contains the enumerated host ID for the Intel
+ SCU controller. The Intel(R) C600 Series Chipset SATA/SAS
+ Storage Control Unit embeds up to two 4-port controllers in
+ a single PCI device. The controllers are enumerated in order
+ which usually means the lowest number scsi_host corresponds
+ with the first controller, but this association is not
+ guaranteed. The 'isci_id' attribute unambiguously identifies
+ the controller index: '0' for the first controller,
+ '1' for the second.

+ * This file contains clockdomains and clockdomain wakeup/sleep
+ * dependencies for the OMAP3xxx chips. Some notes:
+ *
+ * A useful validation rule for struct clockdomain: Any clockdomain
+ * referenced by a wkdep_srcs or sleepdep_srcs array must have a
+ * dep_bit assigned. So wkdep_srcs/sleepdep_srcs are really just
+ * software-controllable dependencies. Non-software-controllable
+ * dependencies do exist, but they are not encoded below (yet).
+ *
+ * The overly-specific dep_bit names are due to a bit name collision
+ * with CM_FCLKEN_{DSP,IVA2}. The DSP/IVA2 PM_WKDEP and CM_SLEEPDEP shift
+ * value are the same for all powerdomains: 2
+ *
+ * XXX should dep_bit be a mask, so we can test to see if it is 0 as a
+ * sanity check?
+ * XXX encode hardware fixed wakeup dependencies -- esp. for 3430 CORE
