Subject: add support for the global coherent pool to the dma core
Date: Mon, 12 Jul 2021 08:16:57 +0200 [thread overview]
Message-ID: <20210712061704.4162464-1-hch@lst.de> (raw)
Hi all,
this series adds support for using the global coherent (aka uncached)
pool to the generic dma-direct code and then switches arm-nommu and
hexagon over to it, together with a bunch of cleanups.
