Pull SCSI updates from James Bottomley: "Updates to the usual drivers (ufs, qla2xx, target, lpfc, smartpqi, mpi3mr). The main driver change that might cause issues on down the road is the conversion of some of our oldest surviving drivers to the DMA API (should only affect m68k). The only major core change is the rework of async resume; the rest are either completely trivial or for updating deprecated APIs" * tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi: (195 commits) scsi: target: Remove XDWRITEREAD emulated support scsi: megaraid: Remove the static variable initialisation scsi: ch: Do not initialise statics to 0 scsi: ufs: core: Fix spelling mistake "Cannnot" -> "Cannot" scsi: target: iscsi: Do not require target authentication scsi: target: iscsi: Allow AuthMethod=None scsi: target: iscsi: Support base64 in CHAP scsi: target: iscsi: Add support for extended CDB AHS scsi: ufs: dt-bindings: Add SC8280XP binding scsi: target: iscsi: Fix clang -Wformat warnings scsi: ufs: core: Read device property for ref clock scsi: libsas: Resume SAS host for phy reset or enable via sysfs scsi: hisi_sas: Modify v3 HW SATA completion error processing scsi: hisi_sas: Relocate DMA unmap of SMP task scsi: hisi_sas: Remove unnecessary variable to hold DMA map elements scsi: hisi_sas: Call hisi_sas_slave_configure() from slave_configure_v3_hw() scsi: mpi3mr: Delete a stray tab scsi: mpi3mr: Unlock on error path scsi: mpi3mr: Reduce VD queue depth on detecting throttling scsi: mpi3mr: Resource Based Metering ...

scsi: ufs: core: Read device property for ref clock

2022-07-19T03:04:12Z

UFS storage devices require bRefClkFreq attribute to be set to operate correctly at high speed mode. The necessary value is determined by what the SoC / board supports. The standard doesn't specify a method to query the value, so the information needs to be fed in separately. DT information feeds into setting up the clock framework, so platforms using DT can get the UFS reference clock frequency from the clock framework. A special node "ref_clk" from the clock array for the UFS controller node is used as the source for the information. On the platforms that do not use DT (e.g. Intel), the alternative mechanism to feed the intended reference clock frequency is necessary. Specifying the necessary information in DSD of the UFS controller ACPI node is an alternative mechanism proposed in this patch. Those can be accessed via firmware property facility in the kernel and in many ways simillar to querying properties defined in DT. This patch introduces a small helper function to query a predetermined ACPI supplied property of the UFS controller, and uses it to attempt retrieving reference clock value, unless that was already done by the clock infrastructure.

scsi: core: Remove reserved request time-out handling

2022-07-06T12:33:53Z

The SCSI core code does not currently support reserved commands. As such, requests which time-out would never be reserved, and scsi_timeout() 'reserved' arg should never be set. Remove handling for reserved requests, drop the wrapper scsi_timeout() as it now just calls scsi_times_out() always, and finally rename scsi_times_out() -> scsi_timeout() to match the blk_mq_ops method name.
