The fact that blk_mq_destroy_queue also drops a queue reference leads
to various places having to grab an extra reference. Move the call to
blk_put_queue into the callers to allow removing the extra references.

Pull SCSI updates from James Bottomley:
"Updates to the usual drivers (qla2xxx, lpfc, ufs, hisi_sas, mpi3mr,
mpt3sas, target). The biggest change (from my biased viewpoint) being
that the mpi3mr now attached to the SAS transport class, making it the

Beyond the usual bug fixing and security class reworks, there aren't a
huge number of core changes"

Userspace may want to manually control when the data should go into
WriteBooster buffer. The control happens via "wb_on" node, but presently,
there is no simple way to check if WriteBooster is supported and
enabled.
Expose the Write Booster and Clock Scaling capabilities to be able to
determine if the Write Booster is available and if its manual control is
blocked by Clock Scaling mechanism.

There is the following quirk to bypass "WB Flush" in Write Booster.
- UFSHCI_QUIRK_SKIP_MANUAL_WB_FLUSH_CTRL
If this quirk is not set, there is no knob that can control "WB Flush".
There are three flags that control Write Booster Feature:
1. WB ON/OFF
2. WB Hibern Flush ON/OFF (implicitly)
3. WB Flush ON/OFF (explicit)
The sysfs attribute that controls the WB was implemented. (1)
In the case of "Hibern Flush", it is always good to turn on. Control may
not be required. (2)
Finally, "Flush" may be necessary because the Auto-Hibern8 is not supported
in a specific environment. So the sysfs attribute that controls this is
necessary. (3)

Mediatek UFS does not want to toggle write booster during clock scaling.
Permit host driver to disable wb toggling during clock scaling.
Introduce a flag UFSHCD_CAP_WB_WITH_CLK_SCALING to decouple WB and clock
scaling. UFSHCD_CAP_WB_WITH_CLK_SCALING is only valid when
UFSHCD_CAP_CLK_SCALING is set. Just like UFSHCD_CAP_HIBERN8_WITH_CLK_GATING
is valid only when UFSHCD_CAP_CLK_GATING set.
Set UFSHCD_CAP_WB_WITH_CLK_SCALING for qcom to compatible legacy design at
the same time.

CLOCK_MONOTONIC is not advanced when the system is in suspend. This becomes
problematic when debugging issues related to suspend-resume: the timestamps
printed by ufshcd_print_trs can not be correlated with dmesg entries, which
are timestamped with local_clock().
Change the used clock to local_clock() for the informational timestamp
variables and adds mirroring *_local_clock instances for variables used in
subsequent derevations (to not change the semantics of those derevations).

Provide clk-scaling feature in MediaTek UFS platforms.
MediaTek platform supports clk-scaling by switching parent clock mux of
UFSHCI main clocks: ufs_sel.
The driver needs to prevent changing the rate of ufs_sel because its parent
PLL clock may be shared between multiple IPs. In order to achieve this
goal, the maximum and minimum clock rates of ufs_sel defined in dts should
match the rate of "ufs_sel_max_src" and "ufs_sel_min_src" respectively.

dsm_fns is a bitmap, and it is 0-indexed according to the check in
__intel_dsm function. But common initialization was checking it as if it
was 1-indexed. This patch corrects the discrepancy. This change won't break
any existing calls to the function, since before the change both bits 0 and
1 were checked and needed to be set.

After ufshcd_wl_shutdown() set device power off and link off,
ufshcd_shutdown() could turn off clock/power. Also remove
pm_runtime_get_sync.
The reason why it is safe to remove pm_runtime_get_sync() is because:
- ufshcd_wl_shutdown() -> pm_runtime_get_sync() will resume hba->dev too.
- device resume(turn on clk/power) is not required, even if device is in
RPM_SUSPENDED.

Measurements for one particular UFS controller + UFS device show a 25%
higher read bandwidth if the maximum data buffer size is increased from 512
KiB to 1 MiB. Hence increase the maximum size of the data buffer associated
with a single request from SCSI_DEFAULT_MAX_SECTORS (1024) * 512 bytes =
512 KiB to 1 MiB.
Notes:
- The maximum data buffer size supported by the UFSHCI specification
is 65535 * 256 KiB or about 16 GiB.
- The maximum data buffer size for READ(10) commands is 65535 logical
blocks. To transfer more than 65535 * 4096 bytes = 255 MiB with a single
SCSI command, the READ(16) command is required. Support for READ(16) is
optional in the UFS 3.1 and UFS 4.0 standards.

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.

The type name enum req_opf is misleading since it suggests that values of
this type include both an operation type and flags. Since values of this
type represent an operation only, change the type name into enum req_op.
Convert the enum req_op documentation into kernel-doc format. Move a few
definitions such that the enum req_op documentation occurs just above
the enum req_op definition.
The name "req_opf" was introduced by commit ef295ecf090d ("block: better op
and flags encoding").

Call ufshcd_scale_clks() instead so that clock change can be properly

Once the host link startup fails 3 times, all host registers are reset to
default values except in ufshcd_hba_enable().
The ufs host controller is disabled and enabled in ufshcd_hba_enable().

values.
