Subject: [PATCH 30/34] powerpc/dma: remove dma_nommu_mmap_coherent
Date: Wed, 14 Nov 2018 09:23:10 +0100	[thread overview]
Message-ID: <20181114082314.8965-31-hch@lst.de> (raw)
In-Reply-To: <20181114082314.8965-1-hch@lst.de>

The coherent cache version of this function already is functionally
identicall to the default version, and by defining the
arch_dma_coherent_to_pfn hook the same is ture for the noncoherent
version as well.
