hmm why not add max_buffer_len in patch 1 again, and then use default
len as XILINX_DMA_MAX_TRANS_LEN and add multiple lengths here :)

Sorry, I'm not getting your point. Could you please elaborate the "add
multiple lengths here" thing ?

IIRC (sorry been travelling and vacation), add
chan->xdev->max_buffer_len in patch 1 and initialize it to
XILINX_DMA_MAX_TRANS_LEN. Then in subsequent patches update the length.
