18 DPCM re-uses all the existing component codec, platform and DAI drivers without
49 of the BE DAIs. The FE PCM devices can also route audio to more than 1 BE DAI.
108 and then DPCM will take care of managing the DAI PCM operations to either bring
119 1. Define the FE and BE DAI links.
126 FE and BE DAI links
146 For the example above we have to define 4 FE DAI links and 6 BE DAI links. The
147 FE DAI links are defined as follows :-
162 .....< other FE and BE DAI links here >
165 This FE DAI link is pretty similar to a regular DAI link except that we also
166 set the DAI link to a DPCM FE with the ``dynamic = 1``. The supported FE stream
170 components (as some DSPs have strong requirements for the ordering DAI/DSP
173 The FE DAI above sets the codec and code DAIs to dummy devices since the BE is
180 .....< FE DAI links here >
195 .....< other BE DAI links here >
198 This BE DAI link connects DAI0 to the codec (in this case RT5460 AIF1). It sets
221 This allows the host CPU to sleep while the DSP, MODEM DAI and the BT DAI are
224 A BE DAI link can also set the codec to a dummy device if the codec is a device
227 Likewise a BE DAI can also set a dummy cpu DAI if the CPU DAI is managed by the
235 callback is used by the machine driver to (re)configure the DAI based upon the
240 DAI0 so that the DAI is running at desired configuration regardless of the FE
261 The other PCM operation are the same as for regular DAI links. Use as necessary.
267 The BE DAI links will normally be connected to the graph at initialisation time
268 by the ASoC DAPM core. However, if the BE codec or BE DAI is a dummy then this
339 2. Hostless FE. This FE has a virtual connection to the BE DAI links on the DAPM
341 This method gives more control over the DAI links, but requires much more
349 This DAI link is enabled when DAPM detects a valid path within the DAPM graph.
350 The machine driver sets some additional parameters to the DAI link i.e.
362 < ... more DAI links above ... >
373 < ... more DAI links here ... >
375 These parameters are used to configure the DAI hw_params() when DAPM detects a
377 call the appropriate PCM operations to disable the DAI when the path is no
384 The DAI link(s) are enabled by a FE that does not read or write any PCM data.
