Subject: [PATCH 0/2] Add support for MEMCPY_SG transfers
Date: Wed, 7 Jul 2021 00:43:36 +0100 [thread overview]
Message-ID: <20210706234338.7696-1-adrian.martinezlarumbe@imgtec.com> (raw)
Bring back dmaengine API support for scatter-gather memcpy's, which is a
follow-up from a previous patch series in which I wrongly tried to
implement the semantics of a MEMCPY_SG through the Slave SG interface.
The second patch fixes a race condition that I observed when calling
dmaengine_terminate_sync in the Xilinx DMA driver.
