Subject: [PATCH v3 12/38] fbdev/ep93xx-fb: Alloc DMA memory from hardware device
Date:   Tue, 13 Jun 2023 13:06:47 +0200
Message-ID: <20230613110953.24176-13-tzimmermann@suse.de>
In-Reply-To: <20230613110953.24176-1-tzimmermann@suse.de>
References: <20230613110953.24176-1-tzimmermann@suse.de>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

Pass the hardware device to the DMA helpers dma_alloc_wc(), dma_mmap_wc()
and dma_free_coherent(). The fbdev device that is currently being used is
a software device and does not provide DMA memory.
