Hi all,

I've continued reviewing the DesignWare I2S driver and referred to
the DesignWare APB I2S databook when looking into its clock
configuration, channel limits, and FIFO handling.

I couldn't access the document through the manufacturer's website
due to regional restrictions, so I've found an externally hosted
copy for convenience. The Synopsys product page is also included
for reference.

Databook:

Manufacturer's website:
https://www.synopsys.com/dw/ipdir.php?c=DW_apb_i2s

Compile-tested only.

Best regards,
Phuc
