I'm working for some time now with running Linux on the mx28evk and I wanted to add watchdog functionality. But how do I do this? In the Linux kernel (3.7.8) I did find a "imx2_wdt.c" in drivers/watchdog, but this does not match the MX28 registers if I look at the reference manual. Also in the "platform-imx2-wdt.c" there are a number of CONFIG_SOC_IMX types listed, but not for the IMX28. It seems to be, that the watchdog implementation for the i.mx28 is quite different from the other i.mx types and therefore this peripheral is not supported (yet).
Can anyone tell me if there is watchdog support for the i.mx28, either in the mainline or in the maintained 2.6.35 kernel? In both versions I have not been able to find this....
