Subject: [PATCH 4/9] mmc: sdhci: add a callback for using tuning block
Date: Thu, 2 Mar 2017 17:47:25 +0800 [thread overview]
Message-ID: <1488448050-7574-5-git-send-email-yangbo.lu@nxp.com> (raw)
In-Reply-To: <1488448050-7574-1-git-send-email-yangbo.lu@nxp.com>
Some non-standard SD host controllers may use tuning block
for executing tuning procedure.
