+<concept id="GUID-10C986FD-BD56-4F8E-87EC-7B890EFCDAC7" xml:lang="en"><title>DMA Chipset Configuration</title><shortdesc>Chipset configuration is performed entirely within the
+platform service implementation.</shortdesc><prolog><metadata><keywords/></metadata></prolog><conbody>
+<p>The DMA controller chipset has multiple DMA channels that can be
+configured for different DMA transfers. Drivers generally initialize
+and open the required DMA channel and use this channel to do the DMA
+transfers. </p>
+<p>For some peripherals, such as the Camera and the Display controller,
+there can be dedicated DMA channels that cannot be configured for
+DMA transfers by other peripherals. </p>
+<p>To configure the channels and other features of the chipset, you
+may need to write code. This code should be executed prior to the
+DMA channels being used for the first time, or to configure dynamically-allocated
+channels.</p>
+<p>This requires chipset specific code which is beyond the scope of
+this documentation. Please refer to your chipset's datasheet and any
+accompanying documentation for details on how to perform any required
+chipset configuration.</p>
+<p><note>If you need to perform chipset configuration after the device
+driver has loaded, there is an <xref href="GUID-93A3F01A-3489-37E5-921C-5EA5228545AA.dita"><apiname>Extension()</apiname></xref> function.
+This function passes chipset specific code or instructions from the
+client to the platform service implementation. Implementation of the <xref href="GUID-93A3F01A-3489-37E5-921C-5EA5228545AA.dita"><apiname>Extension()</apiname></xref> API is platform specific and is not covered
+further in this documentation.</note></p>
