scsi: ufs: dt-bindings: Document gear and rate limit properties
...
Add optional "limit-hs-gear" and "limit-rate" properties to the UFS
controller common binding. These properties allow limiting the maximum
HS gear and rate.
This is useful in cases where the customer board may have signal
integrity, clock configuration or layout issues that prevent reliable
operation at higher gears. Such limitations are especially critical in
those platforms, where stability is prioritized over peak performance.

scsi: ufs: dt-bindings: Add msi-parent for UFS MCQ
...
The Message Signaled Interrupts (MSI) support has been introduced in UFSHCI
version 4.0 (JESD223E). The MSI is the recommended interrupt approach for
MCQ. If choose to use MSI, in UFS DT, we need to provide msi-parent
property that point to the hardware entity which serves as the MSI
controller for this UFS controller.

scsi: ufs: dt-bindings: common: Add OPP table
...
Except scaling UFS and bus clocks, it's necessary to scale also the
voltages of regulators or power domain performance state levels. Adding
Operating Performance Points table allows to adjust power domain
performance state, depending on the UFS clock speed.
OPPv2 deprecates previous property limited to clock scaling:
freq-table-hz.
