Add new kernel driver in yocto

[vinod kumar]

Hi,

I am using yocto for wandboard. I have written one I2C driver for my I2C
device.

 *The procedure which I followed to add and build the driver in yocto is as*
:

1) Make the entry of my driver in Makefile and Kconfig in build directory.
2) Replace the defconfig (present in source directory) with .config
(present in build directory).
3) Add the driver information in device tree file.

Then I run the *bitbake linux-imx -c compile -f* to compile the kernel and
face some errors. So is there any way (like to add as a patch *(patch of
conf file and driver source code*) in some .bbappend file or something
equivalent to it) through which I can add and compile my driver successfully

*But during compilation I faced the below errors:*
