Subject: [PATCH 4/7] spi: rockchip: remove unneeded dma_caps
Date: Wed, 10 Oct 2018 11:00:35 +0200 [thread overview]
Message-ID: <20181010090038.20834-5-kernel@esmil.dk> (raw)
In-Reply-To: <20181010090038.20834-1-kernel@esmil.dk>
We no longer need the dma_caps since the dma driver
already clamps the burst length to the hardware limit,
so don't request and store dma_caps in device data.
