Slow SD Card

I have rebuilt the DT from the link MicroSD card not detected on Jetson Nano production module - #14 by jetson_user. The target Nano did not detect SD card. Only after dtc to the dts file and remove max-clk linmit. Then I can then see SD card. But speed is very slow. I attached the dmesg and ios file to this, please help.
clock (9 Bytes)
dmesg no sd card.txt (127.9 KB)
ios (240 Bytes)
speed (2 Bytes)
