Subject: [PATCH 09/10] mmc: tegra: Perform pad calibration after voltage switch
Date: Tue, 24 Jul 2018 17:34:25 +0300	[thread overview]
Message-ID: <1532442865-6391-8-git-send-email-avienamo@nvidia.com> (raw)
In-Reply-To: <1532442865-6391-1-git-send-email-avienamo@nvidia.com>

Run the automatic pad calibration after voltage switching if
tegra_host->pad_calib_required is set.
