Subject: [PATCH 0/2] spi: stm32-qspi: add dma support
Date: Fri, 22 Mar 2019 15:35:52 +0100 [thread overview]
Message-ID: <1553265354-16433-1-git-send-email-ludovic.Barre@st.com> (raw)
From: Ludovic Barre <ludovic.barre@st.com>
This patch series adds dma support for the stm32-qspi.
In read mode, the memory map is preferred vs dma
(due to better throughput). If the dma transfer fails the buffer is
sent by polling.
