Subject: [PATCH 06/15] mmc: sdhci: Add sdhci_adma_mark_end()
Date: Tue, 21 Oct 2014 12:26:16 +0300	[thread overview]
Message-ID: <1413883585-16299-7-git-send-email-adrian.hunter@intel.com> (raw)
In-Reply-To: <1413883585-16299-1-git-send-email-adrian.hunter@intel.com>

In preparation for 64-bit ADMA, separate out code
that touches the ADMA descriptor by adding
sdhci_adma_mark_end().
