ASoC: codecs: rtq9128: Add TDM input source select
Merge series from [email protected]: This patch series create a TDM source select property and use it to decide which TDM data source is connected. Following by the below patch disccuion https://lore.kernel.org/lkml/[email protected]/#t It may not be a good choice to add the user controlable mixer control item. Since it follows the board design, make it as a device property.
