d01cfeac89 scsi: dt-bindings: mediatek,ufs: add MT8195 compatible and update clock nodes 
Add MT8195 UFSHCI compatible string.  Relax the schema to allow between
one to eight clocks/clock-names entries for all MediaTek UFS
nodes. Legacy platforms may only need a few clocks, whereas newer devices
such as the MT8195 require additional clock-gating domains. For MT8195
specifically, enforce exactly eight clocks and clock-names entries to
satisfy its hardware requirements.

794ff7a0a6 scsi: dt-bindings: mediatek,ufs: Add ufs-disable-mcq flag for UFS host 
Add the 'mediatek,ufs-disable-mcq' property to the UFS device-tree
bindings. This flag corresponds to the UFS_MTK_CAP_DISABLE_MCQ host
capability recently introduced in the UFS host driver, allowing it to
disable the Multiple Circular Queue (MCQ) feature when present.  The
binding schema has also been updated to resolve DTBS check errors.
