Thanks alot for replying
I am learning how to write my own device driver from scratch. I have reference manual for omap4 watchdog timer but I dont know how to start writing my own device driver. The reference manual has a lot of register that need to be configured to make watchdog driver operational but I have no idea how to do that. The file watchdog-apt.txt & watchdog-simple.c discuss the userspace application, not how to write your own device driver. The "The Linux WatchDog Timer Driver Core kernel API" was quite helpfull but I am still lost. If you could point me in the right direction that will be very helpful.
