Thanks for pointing this. In my local machine it was properly done but
while rebasing on linux-next I did some mistake. There is one more
place in set_sysclk which need to be corrected here
mod &= 0 << i2s_regs->rclksrc_off
can you include this change also in your patch or should I post a new
patch for all?
Thanks
