Subject: [RFC PATCH v2 0/6] Add support UHS-II for GL9755

Hi Uffe and Adrian,

These patches support UHS-II and fix GL9755 UHS-II compatibility.

The parts of UHS-II are based on [1][2] and porting to Linux 5.5-rc5.
I have seen that Uffe comment that splitting the UHS-II parts into smaller
patches. Other than splitting into small patches, could you give me some 
suggestions for refactoring/splitting files?

Best regards,
Ben
