Tool/software:
Hi Ti!
We used the sdk ti-processor-sdk-linux-adas-j784s4-evm-10_01_00_05 to test spi5 of J784S4-evm board ，
We had changed the dts file \board-support\ti-linux-kernel-6.6.44+git-ti\arch\arm64\boot\dts\ti\k3-j784s4-evm.dts , the diff is:

\ No newline at end of file
we used make linux-dts to compile it and update the dtb file to /boot/dts/ti ,
when check the /dev after reboot the board , we can not find a "spidev*" int /dev dir ， any other changes we need to check ?
