What I don't understand is why do we need "wdt-reboot" for i.MX in U-Boot?
The i.MX watchdog driver is capable of resetting via internal watchdog or via a WDOG_B pin when the fsl,ext-reset-output property is passed.
Ok, right. Well my patches fixes the 'reset' command in u-boot and for that we need a sysreset driver in u-boot currently.
The watchdog itself works fine IIRC.
My patch adds the 'wdt-reboot' device node which is needed by u-boot to reset the device but doesn't exist in the linux kernel (since there is
Right. This is the point I don't understand: why do we need a U-Boot wdt-reboot implementation in the first place?
The imx watchdog works in the kernel with DT. Why can't you just use the same binding in U-Boot?
Thanks
