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 .

## dts file changes in imx8mm-evk.dts

pinctrl_i2c3: i2c3grp {
           fsl,pins = <
