Subject: [PATCH 14/22] ARM: ux500: Pass MSP DMA platform data though AUXDATA
Date: Thu, 9 Aug 2012 16:47:40 +0100 [thread overview]
Message-ID: <1344527268-5964-15-git-send-email-lee.jones@linaro.org> (raw)
In-Reply-To: <1344527268-5964-1-git-send-email-lee.jones@linaro.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.
