Toshiba was the only device manufacturer with the most accomplished phy team to come up with a small UFS1.0 device. Alas, there were no commercial platforms it can be paired with. Even UFS2.0 that was published in 2013, didn't really make it to the market: too moot to take effect. It's not until UFS2.1 that was published in 2016, were a myriad of devices and platforms flooded the market. Designated to mobile devices, dictates a rapid short lives for those platforms. Hence, we can safely remove those pre-UFS2.0 pieces of code. Changes from v2: - Make it clear that UFSHCI2.0 is not included in this change (Bart). Changes from v2: - leave UFSHCI2.0 out of this change (Bart). Changes from v1: - remove ufshcd_get_local_unipro_ver which practically mean squashing patch 1 & 2 into a single patch (Christoph) - restore an if clause to avoid functional change in ufshcd_compl_one_cqe (Bart) Avri Altman (1): scsi: ufs: Remove support for old UFSHCI versions drivers/ufs/core/ufshcd.c | 158 +++--------------------------------- drivers/ufs/host/ufs-qcom.c | 3 +- include/ufs/ufshcd.h | 2 - include/ufs/ufshci.h | 13 +-- 4 files changed, 15 insertions(+), 161 deletions(-)
