After creating devices using mknod, it is working on expected lines. After
reboot these devices are getting removed and I need to create them manually
Can you please suggest me the procedure to enable it programmatically ? I
tried adding CONFIG_DEVTMPFS=y and CONFIG_DEVTMPFS_MOUNT=y in the def
config, but no luck.
