Hi,
I am trying to insert my touchscreen driver module in linux 3.7 kernel for am335x sitara starter kit . In this architecture its look like i have to do modification for board specific changes in dts file which is new for me.
i have done some changes in dts file to include my i2c driver as a module . I am not familiar with dts code structure so i am suspecting the mux setting is not happening properly.Can anyone help me to do modification to insert my module in "am335x-evmsk.dts" file . Or there is any other way to do boars specific changes.
bellow is the kernel crash ...
