Hi, I am using PCM5102a dac module to i2s@0 for JETSON-tx2 board. This module driver is not located in Linux-tegra kernel source. So I have downloaded the pcm5102a driver from latest kernel 4.17 revision. I have kept it in linux-tegra kernel-source/sound/soc/codexs/ and I modified Makefile and Kconfig file. Driver entry is created in Menuconfig. I have selected it and compiled successfully. Then i have checked in Rootfs inside /sys/snd/ all modules located over there. but my pcm5102a module is not there.
Is there any problem with module driver or Device tree problem.
Now My doubt is
- Is it necessary to add a module entry node inside the DTS file…?
- How to test it.
I am new for this module.
Can you please provide me some information
