Subject: [PATCH 0/2] mmc: mmci: stm32: manage unaligned DMA req for SDIO
Date: Thu, 17 Mar 2022 12:19:42 +0100 [thread overview]
Message-ID: <20220317111944.116148-1-yann.gautier@foss.st.com> (raw)
The first patch corrects an issue when parsing the sg list to check DMA
constraints.
The second patch manages those DMA alignment by copying from or to a
bounce buffer, the way it is done in meson-gx-mmc.
Yann Gautier (2):
mmc: mmci: stm32: correctly check all elements of sg list
mmc: mmci: stm32: use a buffer for unaligned DMA requests
