possible inconsistency in dragonboard HW user manual

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 "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?
