Hi Team ,
I have followed the https://www.nxp.com/docs/en/application-note/AN11697.pdf document and did the changes in yocto project kernel 4.14 . Driver is compiled successfully , .o file is generated . But I am not getting any debug message in my OS booting logs .
Driver is not getting registered .
Kindly suggest me for the same as soon as possible .
