The host controller already report the HS200 mode, and as shown in cover letter HS200 mode is being enabled/used with this series. However, the driver must use different tap/delay num for HS400(ES) modes. At top of [1] there is a commit that changes to use same tap/delay num as vendor kernel and what I have tested worked in U-Boot. That commit needs to be re-worked before it is ready. Also see [2] for pending work before I plan to complete before moving on to the dwcmshc driver.
