Is there a documentation for drivers/stacks?

[bosnian_beast]

For example if I add UART pins and driver to my project, I used functions from the example project "lpupart_polling":

LPUART_ReadBlocking(LPUART2, &ch, 1);
LPUART_WriteBlocking(LPUART1, &ch, 1);

Is there some documentation like on TexasInstruments BLE stack where you can find explanation, use cases and all the functions in the stack?

Or on Android: 

https://developer.android.com/reference/android/bluetooth/BluetoothGattServer

It's just a regular documentation for available functions?

Hello
Hope you are well.
You can find SDK drivers documentation at this link: MCUXpresso SDK API Reference Manual: Introduction (nxp.com)
More documentation can be found under the SDK "docs" folder.

If you have more questions do not hesitate to ask me.
Best regards,
