Subject: [PATCH v2 2/4] MIPS: Always select ARCH_HAS_SETUP_DMA_OPS
Date: Wed, 22 Feb 2023 13:24:23 +0000 [thread overview]
Message-ID: <20230222132425.7442-3-jiaxun.yang@flygoat.com> (raw)
In-Reply-To: <20230222132425.7442-1-jiaxun.yang@flygoat.com>
arch_setup_dma_ops on MIPS sets coherency information in struct device.
It's essential for per-device coherency to work.
Select it for all non-coherent platforms.
