Intel ssp blob can have auxiliary controls catenated as tlv array at the
end of its "normal" data blob. These are needed in some platforms for
example to enable hardware clocks earlier than streaming starts.
In topology the auxiliary data classes are embedded into hw_config and
can be instantiated like:
Object.Base.hw_config."SSP0_0" {
id 0
mclk_freq 38400000
bclk_freq 256000
tdm_slot_width 16
format "DSP_A"
bclk "codec_provider"
fsync "codec_provider"
fsync_freq 16000
Object.Base.mn_config."MN_0" {
m_div 100
n_div 200
}
Object.Base.clk_config."CLK_0" {
clock_warm_up 1
mclk 2
warm_up_ovr 3
clock_stop_delay 4
keep_running 5
clock_stop_ovr 6
}
}
