| |
CPU/Codec in DPCM DAI links are connected as CPU<->Dummy and Dummy<->Codec. Though mostly CPU won't use/require 'mclk-fs' property, looping over 'np' (current child node in a DAI link) can help in cases where multiple Codecs are defined. This further helps to get rid of 'codec' argument from simple_dai_link_of_dpcm() function, which gets called for DPCM links.
