SCSI misc on 20220804

Browse Source 
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.

5. UFS Reference Clock Frequency configuration
==============================================
Devicetree can define a clock named "ref_clk" under the UFS controller node
to specify the intended reference clock frequency for the UFS storage
parts. ACPI-based system can specify the frequency using ACPI
Device-Specific Data property named "ref-clk-freq". In both ways the value
is interpreted as frequency in Hz and must match one of the values given in
the UFS specification. UFS subsystem will attempt to read the value when
executing common controller initialization. If the value is available, UFS
subsytem will ensure the bRefClkFreq attribute of the UFS storage device is
set accordingly and will modify it if there is a mismatch.
