To use ASRC, the sysclk should be faster than 384 times sample rate of I2S1.

Can you start using snd_soc_dapm_to_codec(source->dapm) instead of source->codec? The codec field will eventually be removed.
Bonus points for fixing up the existing w->codec users in rt drivers.
Sure, I will resend the patch. Another question is that the patch is one of 4 patches series. Should I resend all of them?
Thanks.
Thanks,
