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 References: 1. [RFC,1/2] mmc: core: support UHS-II in core stack. (https://patchwork.kernel.org/patch/5544441/) 2. [RFC,2/2] mmc: sdhci: support UHS-II in SDHCI host.
