What document describes the QCA4002 GPIO alternate function assignments for the SPI, I2C, I2S, UART, and JTAG interfaces ?
The device specification just shows the GPIO generic pin names. Is there crossbar matrix somewhere ?
Is there a more detailed QCA4002 datasheet i am missing ?

Hi,
I am not sure if this will help (I too am scratching around looking for information !!)
The GT202 module uses the QCA4002 and has an alternate pin function table in 6.3

Good luck,
