Hi Ulf,
You added one bit definition 'MMC_CAP2_SD_UHS2' in struct mmc_host.caps2.
But there already had a bit definition 'MMC_CAP_UHS2' in struct mmc_host.caps.
#define MMC_CAP_UHS2 (1 << 26) /* Host supports UHS2 mode */
This bit was first appearred in [RFC PATCH V3 01/21] mmc: add UHS-II related definitions in public headers.
These 2 bits seems to be defined for the same purpose, which one should I use?
kindly regards,
Jason Lai
