SCSI: remove unnecessary pci_set_drvdata()

2013-10-14T13:26:04+00:00

Since commit 0998d0631001288a5974afc0b2a5f568bcdecb4d
(device-core: Ensure drvdata = NULL when no driver is bound),
the driver core clears the driver data to NULL after device_release
or on probe failure. Thus, it is not needed to manually clear the
device driver data to NULL.

[SCSI] ufs: configure the attribute for power mode

2013-09-06T23:08:37+00:00

UIC attributes can be set with using DME_SET command for
power mode change. For configuration the link capability
attributes are used, which is updated after successful
link startup.

[SCSI] ufs: add operation for the uic power mode change

2013-09-06T23:06:40+00:00

Setting PA_PWRMode using DME_SET triggers the power mode
change. And then the result will be given by the HCS.UPMCRS.
This operation should be done atomically.

[SCSI] ufs: add dme configuration primitives

2013-09-06T23:01:41+00:00

Implements to support GET and SET operations of the DME.
These operations are used to configure the behavior of
the UNIPRO. Along with basic operation, {Peer/AttrSetType}
can be mixed.

[SCSI] ufs: fix the setting interrupt aggregation counter

2013-09-06T23:00:53+00:00

IACTH(Interrupt aggregation counter threshold) value is allowed
up to 0x1F and current setting value is the maximum.
This value is related with NUTRS(max:0x20) of HCI's capability.
Considering HCI controller doesn't support the maximum, IACTH
setting should be adjusted with possible value.
For that, existing 'ufshcd_config_int_aggr' is split into two part
[reset, configure].

[SCSI] ufs: find out sense data over scsi status values

2013-09-06T22:57:55+00:00

Unlike 'GOOD' and 'CHECK CONDITION', other status values in
Response UPIU may or may not contain sense data. That is returning
sense data isn't obvious. So, in this case the Data Segment Length
field should be checked. If a non-zero value, it means that UPIU
has Sense Data in the Data Segment area.

[SCSI] ufs: don't check resource with devm_ioremap_resource

devm_ioremap_resource does sanity checks on the given resource. No need to

[SCSI] ufs: don't stop controller before scsi_remove_host()

2013-08-26T08:51:28+00:00

scsi_remove_host() sends SYNCHRONIZE CACHE commands for write cache
enabled scsi disk devices.  So stopping controller working shouldn't
be done before scsi_remove_host().
