So after some more looking around in the code, I think the workflow is quite a bit different than what I thought in the previous mail. I think I am supposed to allocate hdlc device using `alloc_hdlcdev` in the `serdev->probe` and then implementing `hdlc->xmit` to send data over UART. But well, I am not sure how to create an HDLC frame? Is there a helper that creates HDLC frame skbuff for me? Or maybe the hdlc implementation is simply not designed to be used for Asynchronous framing [1]. It would be great if someone could explain how to use this HDLC module or point to some resource I might have missed.
