SPI Slave Select error on Jetson TX2 J21 header

Autonomous Machines Jetson & Embedded Systems Jetson TX2

Hello,
I installed SPI using

https://elinux.org/Jetson/TX2_SPI

in which spidev.3.0 was enabled and was working fine on pin 24 on the J21 header

and then I enabled spidev.3.1 using

https://devtalk.nvidia.com/default/topic/1029191/jetson-tx2/spi-3-1-enable/

and rebuild the DTS.

Now when i am using SPI on CS 1 (Pin 26 - J21 Header) TX2 sends the data correctly to one slave.
But when I try to use SPI on CS 0 (Pin 24) TX2 sends data to both the slaves while It should be sending to only one slave.

Any supportive links/code snippets/device tree examples would be really helpful

Thanks
