I've checked some internal wiki page and sof git log. It seems the first amp enabled
on JSL is max98373 running in TDM 4 slot 100fs so 24MHz MCLK seems to be a
reasonable choice. The commis is 5340225a7 ("topology: Add JSL da7219+max98373 support")
+# SSP 1 (ID: 0)
+DAI_CONFIG(SSP, SPK_INDEX, 0, SPK_NAME,
+ SSP_CONFIG(DSP_B, SSP_CLOCK(mclk, 24000000, codec_mclk_in),
+ SSP_CLOCK(bclk, 4800000, codec_slave),
+ SSP_CLOCK(fsync, 48000, codec_slave),
+ SSP_TDM(4, 25, 3, 240),
+ SSP_CONFIG_DATA(SSP, SPK_INDEX, 16)))
I've also tested 19.2MHz on JSL boards and it also works. 1K sinetone playback sounds ok.
Since JSL boards are using 2.304 MHz bclk for max98360a and 3.072 MHz bclk for alc1015 now,
changing to 19.2 MHz mclk seems no benefit.
