I was looking for PCM short frame sync and PCM long frame sync, but they are not present in soc-dai.h (FORMAT_MASK). Is there a way to derive them from other formats or should I just add them?
What do you mean when you say "PCM short frame sync" and "PCM long frame sync"?
Sorry for the late reply, I was away.
What I mean by short/long frame sync is: the frame sync lasts for 1 bit/1 word wide.
Eg.: For short frame sync, we get a frame sync signal for 1 clock before the first bit on the RX/TX.
It is different from I2S mode where the frame sync is inverted and the transition starts 1 clock before the bits and lasts till bit 1.
