Subject: [PATCH v2 2/5] mmc: sdhci-esdhc: Add SDHCI_QUIRK_32BIT_DMA_ADDR
Date: Mon, 29 May 2017 15:54:47 +0200	[thread overview]
Message-ID: <1496066090-85375-2-git-send-email-benoit@wsystem.com> (raw)
In-Reply-To: <1496066090-85375-1-git-send-email-benoit@wsystem.com>

The eSDHC can only DMA from 32-bit-aligned addresses.

This fixes the following test cases of mmc_test:
  11:	Badly aligned write
  12:	Badly aligned read
  13:	Badly aligned multi-block write
  14:	Badly aligned multi-block read
