Subject: [RFC PATCH 2/2] mmc: sdhi: internal_dmac: set dma_parms
Date: Tue, 11 Sep 2018 18:30:50 +0200 [thread overview]
Message-ID: <20180911163050.28072-3-wsa+renesas@sang-engineering.com> (raw)
In-Reply-To: <20180911163050.28072-1-wsa+renesas@sang-engineering.com>
We have our own DMA provider, so we should set the dma_parms properly.
