not sure if this is the right list to point out oddities in the documentation, but i'm reading this:

https://www.96boards.org/db410c-getting-started/HardwareDocs/HWUserManual.md...

and in the ToC, under "Low Speed Expansion Connector", there is no mention of I2S, but in the very next section, "Introduction", under

Actually, it says PCM/I2S, just like the specification.

"I/O Interfaces", one reads:

One 40-pin Low Speed (LS) expansion connector
  UART, SPI, I2S, I2C x2, GPIO x12, DC power
             ^^^

should I2S be added to the ToC for consistency? or am i misreading something?

As per the spec, the LS connector must expose I2S/PCM. In other words, PCM data over I2S interface. In the pinout for the LS connector, the signals are named as PCM_FS, PCM_CLK, PCM_DO and PCM_DI on pins 16, 18, 20 and 22 respectively.

The text under the introduction could be fixed to say I2S/PCM to be consistent with other parts of the documentation including the specification.

Want to submit a patch to the documentation[1]? :-)

Regards, Amit
