Subject: [PATCH 1/4] mmc: sdhci-esdhc: Add SDHCI_QUIRK_32BIT_DMA_ADDR
Date: Wed, 3 May 2017 12:05:22 +0200 [thread overview]
Message-ID: <1493805925-3644-1-git-send-email-benoit@wsystem.com> (raw)
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
Signed-off-by: Benoît Thébaudeau <benoit@wsystem.com>
