This patch add TCF support for DSPI module in other platform. I can't really understand what the purpose of this is, sorry. What are these modes and why would one choose one over the other? Your changelog suggests this is being done per board which implies that it's tuning for performance but that's usually something that should be done in device drivers, not the device tree - perhaps the tuning will change over time as the driver is optimized or perhaps it varies depending on the transfer. The code mentions a DMA option as well, generally where it's available DMA is something that's chosen at runtime based on the length of the transfer.
