# process m4 simple tests -
# simple_test(name, pipe_name, be_name, format, dai_id, dai_format, dai_phy_bits, dai_data_bits dai_bclk)
# 1) name - test filename suffix
# 2) pipe_name - test component pipeline filename in sof/
# 3) be_name - BE DAI link name in machine driver, used for matching
# 4) format - PCM sample format
# 5) dai_id - SSP port number
# 6) dai_format - SSP sample format
# 7) dai_phy_bits - SSP physical number of BLKCs per slot/channel
# 8) dai_data_bits - SSP number of valid daat bits per slot/channel
# 9) dai_bclk - SSP BCLK in HZ
