Subject: [PATCH v2 18/40] mmc: tegra: Perform pad calibration after voltage switch
Date: Fri, 10 Aug 2018 21:08:20 +0300 [thread overview]
Message-ID: <1533924522-1037-19-git-send-email-avienamo@nvidia.com> (raw)
In-Reply-To: <1533924522-1037-1-git-send-email-avienamo@nvidia.com>
Run the automatic pad calibration after voltage switching if
tegra_host->pad_calib_required is set.
