2011-05-27Revert "regulator: Move VCOINCELL to be the last element of ↵Axel Lin
mc13892_regulators array" I check this patch again and found this actually is not a bug because MC13xxx_DEFINE explictly defines the order of each entry in the array. Thus revert the patch.

2011-05-27regulator: Support voltage offsets to compensate for drops in systemMark Brown
Some systems, particularly physically large systems used for early prototyping, may experience substantial voltage drops between the regulator and the consumers as a result of long traces in the system. With these systems voltages may need to be set higher than requested in order to ensure reliable system operation. Allow systems to work around such hardware issues by allowing constraints to supply an offset to be applied to any requested and reported voltages. This is not ideal, especially since the voltage drop may be load dependant, but is sufficient for most affected systems, it is not expected to be used in production hardware. The offset is applied after all constraint processing so constraints should be specified in terms of consumer values not physically configured values.

2011-05-27regulator: Move VCOINCELL to be the last element of mc13892_regulators arrayAxel Lin
In include/linux/mfd/mc13892.h, we define MC13892_VCOINCELL as 23. Thus VCOINCELL should be defined as 23th element in mc13892_regulators array, not the first one. This actually fixes an off-by-one bug while accessing mc13892_regulators array. For example, In mc13892_regulator_probe, we use MC13892_VCAM as array index of mc13892_regulators array. mc13892_regulators[MC13892_VCAM].desc.ops->set_mode = mc13892_vcam_set_mode; Currently, it access mc13892_regulators[12] ,which is VAUDIO not VCAM.

2011-05-27regulator: twl: remap has no meaning for 6030Saquib Herman
TWL6030 does not have remap register. The current implementation causes value of remap to be written to state register, accidentally causing the regulators which are probed to be switched on as well. This is wrong as regulators should be controllable based on calls to enable/disable for TWL regulator framework. Further, the values initialized make no sense as well. We hence remove this from the initalizers and also write to remap register only if the TWL is 4030.

The Blackfin SPORT peripheral is a pretty flexible device. With enough coaching, we can make it generate SPI compatible waveforms. This is desirable as the SPORT can run at much higher clock frequencies than the dedicated on-chip SPI peripheral, and it can do full duplex DMA.

If 'max_loop' is 0, there is no restriction on the number of loop devices. User can create/use the devices as many as minor numbers available. If 'max_part' is 0, it means simply the device doesn't support partitioning. Also note that 'max_part' can be adjusted to power of 2 minus 1 form if needed.

2011-05-26[SCSI] libsas: check dev->gone before submitting sata i/oDan Williams
Head off doomed-to-fail i/o in sas_queuecommand before sending it down the ata path. Before: sd 7:0:0:0: [sdd] Synchronizing SCSI cache ata8: no sense translation for status: 0x00 ata8: translated ATA stat/err 0x00/00 to SCSI SK/ASC/ASCQ 0xb/00/00 ata8.00: device reported invalid CHS sector 0 ata8: status=0x00 { } ata8: no sense translation for status: 0x00 ata8: translated ATA stat/err 0x00/00 to SCSI SK/ASC/ASCQ 0xb/00/00 ata8.00: device reported invalid CHS sector 0 ata8: status=0x00 { } ata8: no sense translation for status: 0x00 ata8: translated ATA stat/err 0x00/00 to SCSI SK/ASC/ASCQ 0xb/00/00 ata8.00: device reported invalid CHS sector 0 ata8: status=0x00 { } sd 7:0:0:0: [sdd] Result: hostbyte=DID_OK driverbyte=DRIVER_SENSE sd 7:0:0:0: [sdd] Sense Key : Aborted Command [current] [descriptor] sd 7:0:0:0: [sdd] Add.

2011-05-26[SCSI] libsas: fix/amend device gone notification in sas_deform_port()Dan Williams
Commit 56dd2c06 "libsas: Don't issue commands to devices that have been hot-removed" edited Darrick's original patch to remove setting 'gone' in the sas_deform_port() path because that prevented scsi sync cache commands from being issued when the driver was unloaded. However, this allows true device gone notifications (as signaled port phy events) to trigger sync cache commands to devices that are known to be unreachable. Teach libsas which sas_deform_port() invocations are likely device gone events. Signed-off-by: Dan Williams <dan.j.williams@intel.com> Signed-off-by: James Bottomley <jbottomley@parallels.com>

2011-05-26spi/tle620x: add missing device_remove_file()Axel Lin
This patch includes below fixes: 1. Add missing device_remove_file for dev_attr_status_show in tle62x0_remove. 2. Fix tle62x0_probe error handling: Currently, if the error happens when ptr > 0, gpio_attrs[0] is not properly remove.
