Selecting one of them clearly is needed more information like cpu_dai_name, of_node. The reason why the dai_links have to use 'samsung-i2s' for cpu_dai is that 'samsung-i2s-sec' doesn't have a capture functionality. Without this code, cpu_dai will be selected the first one of the component_list. For example, if I describe nothing to cpu_dai_name, 'samsung-i2s-sec' might be selected to HiFi Primay.
