Hi Jason,
I've tested with and without the CONFIG_OF define.
The first time I’ve used the kirkwood_defconfig without modifications,
the second time I’ve enabled only the CONFIG_MACH_SHEEVAPLUG and
disabled USE_OF.
In both cases the orion_wdt driver compile without any warning.
Thanks for the review.
Best regards
