From mboxrd@z Thu Jan 1 00:00:00 1970 From: tushar.behera@linaro.org (Tushar Behera) Date: Wed, 29 Aug 2012 10:16:24 +0530 Subject: [PATCH 1/2] ARM: EXYNOS: Set the capability of pdm0 and pdm1 as DMA_PRIVATE In-Reply-To: <1346215585-31023-1-git-send-email-tushar.behera@linaro.org> References: <1346215585-31023-1-git-send-email-tushar.behera@linaro.org> Message-ID: <1346215585-31023-2-git-send-email-tushar.behera@linaro.org> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org DMA clients pdma0 and pdma1 are internal to the SoC and are used only by dedicated peripherals. Since they cannot be used for generic purpose, their capability should be set as DMA_PRIVATE.
