2012-01-09sh: pfc: Add config_reg_helper() functionMagnus Damm
Add a helper function for shared config reg access calculations. This allows us to reduce the amount of duplicated code, and at the same time prepare for a common place for future variable bitwidth config reg support.

2012-01-09sh: pfc: Convert index to field and value pairMagnus Damm

2012-01-08pata_bf54x: fix BMIDE status register emulationSergei Shtylyov
The author of this driver clearly wasn't familiar with the BMIDE specification (also known as SFF-8038i) when he implemented the bmdma_status() method: first, the interrupt bit of the BMIDE status register corresponds to nothing else but INTRQ signal (ATAPI_DEV_INT here); second, the error bit is only set if the controller encounters issue doing the bus master transfers, not on the IDE DMA burst termination interrupts like here (moreover, setting the error bit doesn't cause an interrupt). We now need to disable all those unused interrupts... (The only thing I couldn't figure out is how to flush the FIFO to memory once the interrupt happens as required by the mentioned spec.)

2012-01-08[SCSI] runtime resume parent for child's system-resumeLin Ming
[Patch description from Alan Stern] If a child device was runtime-suspended when a system suspend began, then there will be nothing to prevent its parent from runtime-suspending as soon as it is woken up during the system resume. Then when the time comes to resume the child, the resume will fail because the parent is already back at low power. On the other hand, there are some devices which should remain at low power across an entire suspend-resume cycle. The details depend on the device and the platform. This suggests that the PM core is not the right place to solve the problem. One possible solution is for the subsystem or device driver to call pm_runtime_get_sync(dev->parent) at the start of the system-resume procedure and pm_runtime_put_sync(dev->parent) at the end.

2012-01-08[SCSI] check runtime PM status in system PMLin Ming
The only high-level SCSI driver that currently implements runtime PM is sd, and sd treats runtime suspend exactly the same as the SUSPEND and HIBERNATE stages of system sleep, but not the same as the FREEZE stage. Therefore, when entering the SUSPEND or HIBERNATE stages of system sleep, we can skip the callback to the driver if the device is already in runtime suspend. When entering the FREEZE stage, however, we should first issue a runtime resume. The overhead of doing this is negligible, because a suspended drive would be spun up during the THAW stage of hibernation anyway.

2012-01-08[SCSI] add flag to skip the runtime PM calls on the hostLin Ming
With previous change, now the ata port runtime suspend will happen as: disk suspend --> scsi target suspend --> scsi host suspend --> ata port suspend ata port(parent device) suspend need to schedule scsi EH which will resume scsi host(child device). Then the child device resume will in turn make parent device resume first. This is kind of recursive. This patch adds a new flag Scsi_Host::eh_noresume. ata port will set this flag to skip the runtime PM calls on scsi host.

For example, the ata port runtime suspend will happen as, disk suspend --> scsi target suspend --> scsi host suspend --> ata port suspend.

2012-01-08ahci: start engine only during soft/hard resetsTejun Heo
This is another attempt at fixing the same problem that 270dac35c2 (libata: ahci_start_engine compliant to AHCI spec) tried to solve. Unfortunately, 270dac35c2 created regressions for a lot more common controllers and got reverted. This specific AHCI IP block becomes a brick if the DMA engine is started while DRQ is set. It is not possible to avoid the condition completely but the most common occurrence is caused by spurious use of ahci_start_engine() from ahci_start_port() during init sequence. DMA engine is started after both soft and hard resets and ahci_start_port() is always followed by resets, so there is no reason to start DMA engine from ahci_start_port(). This patch removes ahci_start_engine() invocation from ahci_start_port(). This change makes failure path of ahci_port_suspend() leave engine stopped without following resets. This is resolved by replacing ahci_start_port() call with ata_port_freeze() which forces resets afterwards, which is the better behavior anyway.
