From mboxrd@z Thu Jan 1 00:00:00 1970 From: lee.jones@linaro.org (Lee Jones) Date: Thu, 20 Sep 2012 14:12:37 +0200 Subject: [PATCH 19/32] ARM: ux500: Pass MSP DMA platform data though AUXDATA In-Reply-To: <1348143170-2130-1-git-send-email-lee.jones@linaro.org> References: <1348143170-2130-1-git-send-email-lee.jones@linaro.org> Message-ID: <1348143170-2130-20-git-send-email-lee.jones@linaro.org> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org It isn't currently possible to pass all platform specific configuration though Device Tree. Thinks like device names used in the clock infrastructure, call-backs and DMA information have to be passed in via AUXDATA structures and the MSP is no exception. Here we're passing DMA settings.
