Subject: [PATCH 07/11] of: address: Follow DMA parent for "dma-coherent"
Date: Thu, 26 Sep 2019 19:24:51 -0500 [thread overview]
Message-ID: <20190927002455.13169-8-robh@kernel.org> (raw)
In-Reply-To: <20190927002455.13169-1-robh@kernel.org>
From: Robin Murphy <robin.murphy@arm.com>
Much like for address translation, when checking for DMA coherence we
should be sure to walk up the DMA hierarchy, rather than the MMIO one,
now that we can accommodate them being different.
