- * How to use SRC bypass mode for debugging
- *
- * SRC has bypass mode, and it is useful for debugging.
- * In Gen2 case,
- * SRCm_MODE controls whether SRC is used or not
- * SSI_MODE0 controls whether SSIU which receives SRC data
- * is used or not.
- * Both SRCm_MODE/SSI_MODE0 settings are needed if you use SRC,
- * but SRC bypass mode needs SSI_MODE0 only.
- *
- * This driver request
- * struct rsnd_src_platform_info {
- * u32 convert_rate;
- * int dma_id;
- * }
- *
- * rsnd_src_convert_rate() indicates
- * above convert_rate, and it controls
- * whether SRC is used or not.
- *
- * ex) doesn't use SRC
- * static struct rsnd_dai_platform_info rsnd_dai = {
- * .playback = { .ssi = &rsnd_ssi[0], },
- * };
- *
- * ex) uses SRC
- * static struct rsnd_src_platform_info rsnd_src[] = {
- * RSND_SCU(48000, 0),
- * ...
- * };
