Hi,

My comment:

Recommend to add 0 Ohm resistor for MCLK, BCLK, WCLK, DIN and DOUT to suppress unwanted ringing, same thing for SPI signals if they intend to use that.
I don't see I2C pullup resistors, just make sure it's not needed or needed in their platform.
Use 47uF cap on C55 and C57.
Use 22uF on C52.

Regards.
