Thus for the host which doesn't have vqmmc, or its vqmmc does not support 1.2v, directly use MMC_CAP2_HS200 may cause HS200 failure. So needs to check if vqmmc is able to support 1.2v. If it does not support, disable 1.2v IO for HS200. Signed-off-by: Chuanxiao Dong Signed-off-by: Ulf Hansson --- Reading git-diff-tree failed
