Hi Abel,

Validated MCQ on SM8750 and SM8650 now with ESI both enabled and 
disabled, and it is working as expected with no errors observed. 
Mounting, read/write operations, and runtime suspend/resume were 
validated successfully. will post the MCQ enablement device tree changes 
for these targets tomorrow.

It appears that some changes may be missing on Eliza, which will need to 
be debugged separately.

Regards,
Nitin
