Both set EXYNOS_UFS_OPT_SKIP_CONFIG_PHY_ATTR, the conclusion is correct for gs101 as well. With this addressed: Reviewed-by: Tudor Ambarus <tudor.ambarus@linaro.org> nitpick/personal preference: I wouldn't use the commit body as a continuation of the subject. I would specify what the commit does in the body as well. No need to address. Also, as a side note, I thought of removing tx_dif_p_nsec from exynos7_uic_attr, but it seems that this struct is used by exynos_ufs_drvs as well, which don't set EXYNOS_UFS_OPT_SKIP_CONFIG_PHY_ATTR. That's a little confusing, I guess it's more clear if each driver has its own required settings specified.

Firstly exynosauto sets EXYNOS_UFS_OPT_SKIP_CONFIG_PHY_ATTR so setting tx_dif_p_nsec has no effect. Secondly this assignment can't get executed as samsung,sysreg dt property is provided in for this platform. Meaning the execution flow will return on regmap_update_bits call above.
