Subject: [PATCH 3/3] arm64: dts: mt8183: use restricted swiotlb for scp mem
Date: Tue, 23 Nov 2021 19:21:04 +0800 [thread overview]
Message-ID: <20211123112104.3530135-4-hsinyi@chromium.org> (raw)
In-Reply-To: <20211123112104.3530135-1-hsinyi@chromium.org>
Use restricted-dma-pool for mtk_scp's reserved memory. And set the
io-tlb-segsize to 4096 since the driver needs at least 2560 slabs to
allocate memory.
