I use the devkit board for AGX Xavier.
The current state is that the SPI transfer jitter of r3531 (K5.10) is greater. However, r3274 (K4.9) is lower (better performance).
Do you want me to follow the method you mentioned? That is to copy the spi-tegra114.c file from 4.9 into 5.10. If we use this method, do we still need to recompile the Linux kernel?
