How can fast read spi data at TX1 r28.1?

Now I need fast read spi data .I first read spi 100 bytes,then second read spi 100 bytes.but the first read and the second read have a 10ms delay.

How can remove the 10ms delay?

Could you try add the polling-mode and disable-runtime-pm in your DT to try

spi@xxxxxx {
  •   nvidia,polling-mode;
    
  •   nvidia,disable-runtime-pm;
      status = "okay";
    
    };
