--- Work with patch set: SOF-Kernel(7): ASoC: SOF: Add debug_mode flag in sof dev ASoC: SOF: debug: add debugmode debugfs for sof_dev debug_mode ASoC: SOF: uapi: topology: Add SOF_TKN_DAI_LBM_KCONTROL for ssp loopback mode kcontrol ASoC: SOF: add headers for switch control callback functions ASoC: SOF: add switch kcontrol callback functions ASoC: SOF: topology: Add DAI TOKEN string bool parser ASoC: SOF: topology: Add topology handler for dai lbm kcontrol
SOF(5): dai: add lbm status for dai ssp dai: add get_loopback_mode function DMIC: add empty get_loopback_mode function SSP: support for get/set_loopback_mode functions dai: add dai_cmd support for loopback mode switch
SOF-Tools(3): topology: Add SOF_TKN_DAI_LBM_KCONTROL for ssp loopback mode kcontrol topology: m4: add dai lbm kcotnrol support topology: test: Add loopback topology
