Nit: The value above signifies, 16 data transfers per burst.
So ideally it would be good to rename it to reflect that. say,

TMC_AXICTL_WR_BURST_16

nit: It would be nice to group the STS_ and FFCR_ bits together.
Also I see that the defintion for

TMC_STS_FULL is added in a completely unrelated patch (TMC-ETF AUX SPACE
patch ?). It would be good to add it either here or in a different patch.

Otherwise looks good.
